The document can help you quickly understand module interface specifications, as well as the electrical and mechanical details. Associated with application note and user guide, you can use MC60 module to design and set up mobile applications easily. 1.1. Safety Information The following safety precautions must be observed during all phases of the operation, such as usage, service or repair of any cellular terminal or mobile incorporating MC60 module. Manufacturers of the cellular terminal should send the following safety information to users and operating personnel, and incorporate these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for the customers failure to comply with these precautions. Full attention must be given to driving at all times in order to reduce the risk of an accident. Using a mobile while driving (even with a handsfree kit) causes distraction and can lead to an accident. You must comply with laws and regulations restricting the use of wireless devices while driving. Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is switched off. The operation of wireless appliances in an aircraft is forbidden, so as to prevent interference with communication systems. Consult the airline staff about the use of wireless devices on boarding the aircraft, if your device offers a Airplane Mode which must be enabled prior to boarding an aircraft. Switch off your wireless device when in hospitals, clinics or other health care facilities. These requests are desinged to prevent possible interference with sentitive medical equipment. MC60_Hardware_Design Confidential / Released 10 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design Cellular terminals or mobiles operating over radio frequency signal and cellular network cannot be guaranteed to connect in all conditions, for example no mobile fee or with an invalid SIM card. While you are in this condition and need emergent help, please remember using emergency call. In order to make or receive a call, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength. Your cellular terminal or mobile contains a transmitter and receiver. When it is ON , it receives and transmits radio frequency energy. RF interference can occur if it is used close to TV set, radio, computer or other electric equipment. In locations with potencially explosive atmospheres, obey all posted signs to turn off wireless devices such as your phone or other cellular terminals. Areas with potencially explosive atmospheres include fuelling areas, below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles such as grain, dust or metal powders, etc. MC60_Hardware_Design Confidential / Released 11 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design 2 Product Concept 2.1. General Description MC60 is a multi-purpose module which integrates a high performance GNSS engine and a dual-band GSM/GPRS engine.

Application Modes Introduction MC60 module integrates both GSM and GNSS engines which can work as a whole (all-in-one solution) unit or work independently (stand-alone solution) according to customer demands. MC60_Hardware_Design Confidential / Released 25 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design In all-in-one solution, the MC60 works as a whole unit. The GNSS Part can be regarded as a peripheral of the GSM Part. This allows for convenient communication between GSM and GNSS Parts, such as AT command sending for GNSS control, GNSS part firmware upgrading, and EPO data download. In stand-alone solution, GSM and GNSS Parts work independently, and thus have to be controlled separately. All-in-one solution and stand-alone solution schematic diagrams are shown below. Figure 3: All-in-one Solution Schematic Diagram Figure 4: Stand-alone Solution Schematic Diagram MC60_Hardware_Design Confidential / Released 26 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design Table 8: Comparison between All-in-one and Stand-alone Solution All-in-one.

Power Supply 3.3.1. Power Features The power supply of the GSM part is one of the key issues in MC60 module design. Due to the 577us radio burst in GSM part every 4.615ms, the power supply must be able to deliver high current peaks in a burst period. During these peaks, drops on the supply voltage must not exceed the minimum working voltage of the module. For MC60 module, the maximum current consumption could reach 1.6A during a burst transmission. It will cause a large voltage drop on the VBAT. In order to ensure stable operation of the module, it is recommended that the maximum voltage drop during the burst transmission does not exceed 400mV. MC60_Hardware_Design Confidential / Released 27 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design Figure 5: Voltage Ripple during Transmitting 3.3.2. Decrease Supply Voltage Drop 3.3.2.1. Decrease Supply Voltage Drop for GSM Part Power supply range of the GSM part is from 3.3V to 4.6V. Make sure that the input voltage will never drop below 3.3V even in a burst transmission. If the power voltage drops below 3.3V, the module will be turned off automatically. For better power performance, it is recommended to place a 100uF tantalum capacitor with low ESR (ESR=0.7) and ceramic capacitors 100nF, 33pF and 10pF near the VBAT pin. A reference circuit is illustrated in the following figure. The VBAT trace should be wide enough to ensure that there is not too much voltage drop during burst transmission. The width of trace should be no less than 2mm; and in principle, the longer the VBAT trace, the wider it will be. Figure 6: Reference Circuit for the VBAT Input MC60_Hardware_Design Confidential / Released 28 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design 3.3.2.2. Decrease Supply Voltage Drop for GNSS Part The same as VBAT, power supply range of GNSS part is from 2.8 to 4.3V. Typical GNSS_VCC peak current is 40mA during GNSS acquisition after power up. So it is important to supply sufficient current and make the power clean and stable. The decouple combination of 10uF and 100nF capacitor is recommended nearby GNSS_VCC pin. A reference circuit is illustrated in the following figure. Figure 7: Reference Circuit for the GNSS_VCC Input 3.3.3. Reference Design for Power Supply 3.3.3.1. Reference Design for Power Supply of GSM Part In all-in-one solution, the GSM part controls the power supply of the GNSS part. Therefore, the GSM part share the same power circuit design in both all-in-one and stand-alone solutions. The power supply of GSM part is capable of providing sufficient current up to 2A at least. If the voltage drop between the input and output is not too high, it is suggested to use a LDO as the modules power supply. If there is a big voltage difference between the input source and the desired output (VBAT), a switcher power converter is recommended to be used as the power supply. The following figure shows a reference design for +5V input power source for GSM part. The designed output for the power supply is 4.0V and the maximum load current is 3A. In addition, in order to get a stable output voltage, a zener diode is placed close to the pins of VBAT. As to the zener diode, it is suggested to use a zener diode whose reverse zener voltage is 5.1V and dissipation power is more than 1 Watt. MC60_Hardware_Design Confidential / Released 29 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design Figure 8: Reference Circuit for Power Supply of the GSM Part NOTE It is suggested to control the modules main power supply (VBAT) via LDO enable pin to restart the module when the module becomes abnormal. Power switch circuit like P-channel MOSFET switch circuit can also be used to control VBAT. 3.3.3.2. Reference Design for Power Supply of GNSS Part in All-in-one Solution In all-in-one solution, the power supply of GNSS part is controlled by the GSM part through the GNSS_VCC_EN pin. A reference circuit for the GNSS part power supply is given below. Please pay attention to the electrical characteristics of GNSS_VCC_EN to match LDOs EN pin. Please refer to document [1] for details about the AT commands for GNSS control.

Reference Design for Power Supply of GNSS Part in Stand-alone Solution In stand-alone solution, GNSS is independent to the GSM part, and the power supply of the GNSS part is controlled by customers master control. A reference circuit for the power supply of GNSS part is given below. Figure 10: Reference Circuit Design for GNSS Part in Stand-alone Solution MC60_Hardware_Design Confidential / Released 31 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design 3.3.4. Monitor Power Supply The command AT+CBC can be used to monitor the supply voltage of the GSM part. The unit of the displayed voltage is mV. For details, please refer to document [1]. 3.3.5. Backup Domain of GNSS The RTC (Real Time Clock) function of GSM part and backup mode of GNSS part are supported. In GNSSs backup mode, the backup domain which contains all the necessary GNSS information for quick start-up and a small amount of user configuration variables is alive. Due to the backed-up memory, EASY technology is available. 3.3.5.1. Use VBAT as the Backup Power Source of GNSS In either all-in-one or stand-alone solution, GNSSs backup mode will be active as long as the main power supply (VBAT) is remained, even when the module is turned off and GNSS_VCC is powered off; as the GNSSs backup domain is powered by VBAT. In this case, the VRTC pin can be kept floating. When powered by VBAT, the reference internal circuit design in all-in-one and stand-alone solutions is shown below. Figure 11: Internal GNSSs Backup Domain Power Construction 3.3.5.2. Use VRTC as Backup Power of GNSS In either all-in-one or stand-alone solution, when the main power supply (VBAT) is removed after the module is turned off, and GNSS_VCC is also powered off, a backup supply such as a coin-cell battery

(rechargeable or non-chargeable) or a super capacitor can be used to power the VRTC pin to keep GNSS MC60_Hardware_Design Confidential / Released 32 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design in backup mode. When powered by VRTC, the reference internal circuit design in all-in-one and stand-alone solutions is shown below. Figure 12: VRTC is Powered by a Rechargeable Battery Figure 13: VRTC is Powered by a Capacitor A rechargeable or non-chargeable coin-cell battery can also be used here.

MC60_Hardware_Design Confidential / Released 33 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design 3.4. Operating Modes 3.4.1. Operating Modes of GSM Part The table below briefly summarizes the various operating modes of GSM part mentioned in the following chapters. Table 9: Operating Modes Overview of GSM Part Modes Function GSM Normal Operation GSM/GPRS Sleep GSM IDLE GSM TALK GPRS IDLE GPRS STANDBY GPRS READY GPRS DATA In this mode, is ongoing. After enabling sleep mode by AT+QSCLK=1, the GSM part will automatically enter into Sleep Mode if DTR is set to high level and there is no interrupt (such as GPIO interrupt or data on UART port). In this case, the current consumption of the GSM part will reduce to the minimal level. During Sleep Mode, the GSM part can still receive paging message and SMS from the system normally. Software is active. The GSM part has registered on GSM network, and it is ready to send and receive GSM data. GSM connection the power consumption is decided by the configuration of Power Control Level (PCL), dynamic DTX control and the working RF band. The GSM part is not registered on GPRS network. It is not reachable through GPRS channel. The GSM part is registered on GPRS network, but no GPRS PDP context is active. The SGSN knows the Routing Area where the module is located at. The PDP context is active, but no data transfer is ongoing. The GSM part is ready to receive or send GPRS data. The SGSN knows the cell where the module is located at. There this mode, power consumption is decided by the PCL, working RF band and GPRS multi-slot configuration. is GPRS data transfer. In in POWER DOWN Minimum Functionality Mode

(without removing power supply) Normal shutdown by sending the AT+QPOWD=1 command or using the PWRKEY pin. The power management ASIC disconnects the power supply from the base band part of the GSM part. Software is not active. The UART interfaces are not accessible. Operating voltage (connected to VBAT) remains applied. AT+CFUN command can set the GSM part to a minimum functionality mode without removing the power supply. In this case, the RF part of the GSM part will not work or the SIM card will not be accessible, or both RF part and SIM card will be disabled; but the UART port is still accessible. The power consumption in this MC60_Hardware_Design Confidential / Released 34 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design case is very low. Based on system requirements, there are several actions to drive the GSM part to enter into low current consumption status. For example, AT+CFUN can be used to set the part into minimum functionality mode, and DTR hardware interface signal can be used to lead the system to Sleep Mode. 3.4.1.1. Minimum Functionality Mode Minimum functionality mode reduces the functionality of the GSM part to a minimum level. The consumption of the current can be minimized when the slow clocking mode is activated at the same time. The mode is set via the AT+CFUN command which provides the choice of the functionality levels

<fun>=0, 1, 4. 0: minimum functionality 1: full functionality (default) 4: disable from both transmitting and receiving RF signals If the GSM part is set to minimum functionality by AT+CFUN=0, the RF function and SIM card function would be disabled. In this case, the UART port is still accessible, but all AT commands related with RF function or SIM card function will be unavailable. If the GSM part is set by the command AT+CFUN=4, the RF function will be disabled, but the UART port is still active. In this case, all AT commands related with RF function will be unavailable. After the GSM part is set by AT+CFUN=0 or AT+CFUN=4, it can return to full functionality mode by AT+CFUN=1. For detailed information about AT+CFUN, please refer to document [1]. 3.4.1.2. SLEEP Mode SLEEP mode is disabled by default. It can be enabled by AT+QSCLK=1 and the premise is that the GNSS is powered off. The default setting is AT+QSCLK=0, and in this mode, the GSM part cannot enter SLEEP mode. When the GSM part is set by the command AT+QSCLK=1, you can control the part to enter into or exit from the SLEEP mode through pin DTR. When DTR is set to high level, and there is no on-air or hardware interrupt such as GPIO interrupt or data on UART port, the GSM part will enter into SLEEP mode automatically. In this mode, the GSM part can still receive voice, SMS or GPRS paging from network, but the UART port does not work. MC60_Hardware_Design Confidential / Released 35 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design 3.4.1.3. Wake up GSM Part from SLEEP Mode When the GSM part is in the SLEEP mode, it can be woken up through the following methods:

If the DTR Pin is set low, it would wake up the GSM part from the SLEEP mode. The UART port will be active within 20ms after DTR is changed to low level. Receiving a voice or data call from network wakes up the GSM part. Receiving an SMS from network wakes up the GSM part. NOTE DTR pin should be held at low level during communication between the GSM part and the DTE. 3.4.2. Operating Modes of GNSS Part 3.4.2.1. Full on Mode Full on mode includes tracking mode and acquisition mode. Acquisition mode is defined as that the GNSS part starts to search satellites, and to determine the visible satellites, coarse carrier frequency & code phase of satellite signals. When the acquisition is completed, it switches to tracking mode automatically. Tracking mode is defined as that the GNSS part tracks satellites and demodulates the navigation data from specific satellites. When the GNSS_VCC is valid, the GNSS part will enter into full on mode automatically. The following table describes the default configuration of full on mode. Table 10: Default Configuration of Full on Mode (GNSS Part) Item Baud Rate Protocol Update Rate SBAS AIC LOCUS Configuration Comment 115200bps NMEA 1Hz Enable Enable Disable RMC, VTG, GGA, GSA, GSV and GLL MC60_Hardware_Design Confidential / Released 36 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design Easy Technology Enable EASY will be disabled automatically when update rate exceeds 1Hz. GNSS GPS+GLONASS In full on mode, the consumption complies with the following regulations:

When the GNSS part is powered on, the average current will rush to 40mA and last for a few seconds;

then the consumption will be decreased to the acquisition current marked in table 3 and we defined this state as acquisition state, and also it will last for several minutes until it switches to tracking state automatically. The consumption in tracking state is less than that in acquisition state. The value is also listed in table 3. Sending PMTK commands allows for switching among multiple positioning systems:

$PMTK353,0,1*36: search GLONASS satellites only

$PMTK353,1,0*36: search GPS satellites only

$PMTK353,1,1*37: search GLONASS and GPS satellites NOTE In all-in-one solution, make sure the GNSS part is powered on before sending these PMTK commands. 3.4.2.2. Standby Mode Standby mode is a low-power consumption mode. In standby mode, the internal core and I/O power domain are still active; but RF and TCXO are powered off, and the GNSS part stops satellites search and navigation. The way to enter into or exit from standby mode is using PMTK commands. When the GNSS part exits from standby mode, it will use all internal aiding information like GNSS time, ephemeris, last position, etc., to ensure the fastest possible TTFF in either Hot or Warm start. The typical current consumption is about 500uA @GNSS_VCC=3.3V in standby mode. Sending the following PMTK command can make GNSS part enter into standby mode:

$PMTK161,0*28: make sure the GNSS part is powered on before sending the command in all-in-one solution. The following methods will make GNSS part exit from standby mode:

Sending any data via UART will make GNSS part exit from standby mode in all-in-one solution. Sending any data via GNSS_UART will make GNSS part exit from standby mode in stand-alone solution. MC60_Hardware_Design Confidential / Released 37 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design 3.4.2.3. Backup Mode Backup mode requires lower power consumption than standby mode. In this mode, the GNSS part stops acquiring and tracking satellites, but the backed-up memory in backup domain which contains all the necessary GNSS information for quick start-up and a small amount of user configuration variables is alive. Due to the backed-up memory, EASY technology is available. The current consumption in this mode is about 14uA. The following methods will make GNSS part enter into backup mode:

Sending PMTK command $PMTK225,4*2F will make GNSS part enter into backup mode. Cutting off GNSS_VCC and keeping VRTC powered will make GNSS part enter into back mode from full on mode. The following method will make GNSS part exit from backup mode:

As long as the GNSS_VCC is powered, the GNSS part will exit from backup mode and enter full on mode immediately. NOTES In all-in-one solution, all PMTK commands used for the GNSS part should be sent through GSM UART when the GSM part is in Normal Mode or Minimum Functionality Mode and when the GNSS part is powered on. Make sure the GSM UART Port is accessible. In all-in-one solution, if the GSM part is in sleep mode, it is recommended to set the GNSS part to backup mode to save power. This is because the GSM UART Port does not work in sleep mode, and due to this, customers cannot obtain the location information through GSM UART Port even if the GNSS part works in normal mode. In stand-alone solution, all PMTK commands used for the GNSS part can be sent through GNSS UART in any mode of GSM part. 1. 2. 3. 3.4.3.

Power on and down Scenarios in All-in-one Solution In all-in-one solution, GNSS function is turned on or off by the AT command sent from GSM part. 3.5.1. Power on The module can be turned on by driving the pin PWRKEY to a low level voltage. An open collector driver circuit is suggested to control the PWRKEY. A simple reference circuit is illustrated as below. Figure 14: Turn on the Module with an Open-collector Driver MC60_Hardware_Design Confidential / Released 39 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design NOTES 1. MC60 module is set to autobauding mode (AT+IPR=0) by default. In autobauding mode, URC RDY is not reported to the host controller after the module is powered on. When the module is powered on after a delay of 4 or 5 seconds, it can receive AT commands. Host controller should first send an AT string in order that the module can detect baud rate of host controller, and it should continue to send the next AT string until receiving OK string from the module. Then enter AT+IPR=x;&W to set a fixed baud rate for the module and save the configuration to flash memory of the module. After these configurations, the URC RDY would be received from the UART Port of the module every time when the module is powered on. For more details, refer to the section AT+IPR in document [1]. 2. When AT command is responded, it indicates the module is turned on successfully; or else the module fails to be turned on. The other way to control the PWRKEY is through a button directly. While pressing the key, electrostatic strike may generate from the finger, and thus, a TVS component is indispensable to be placed nearby the button for ESD protection. For the best performance, the TVS component must be placed nearby the button. A reference circuit is shown in the following figure. Figure 15: Turn on the Module with a Button Command AT+QGNSSC=1 should be sent to enable the GNSS power supply after the GSM part is running. When the GNSS_VCC is valid, the GNSS will enter into full on mode automatically. The turn-on timing is illustrated in the following figure. MC60_Hardware_Design Confidential / Released 40 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design NOTE Figure 16: Turn-on Timing Make sure that VBAT is stable before pulling down PWRKEY pin. The time of T1 is recommended to be 100ms. 3.5.2. Power down The following procedures can be used to turn off the module:

Normal power down procedure: Turn off module using the PWRKEY pin Normal power down procedure: Turn off module using command AT+QPOWD Under-voltage automatic shutdown: Take effect when under-voltage is detected. 3.5.2.1. Power down Module Using the PWRKEY Pin It is a safe way to turn off the module by driving the PWRKEY to a low level voltage for a certain time. The power down scenario is illustrated in the following figure. The power down procedure causes the module to log off from the network and allows the firmware to MC60_Hardware_Design Confidential / Released 41 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design save important data before completely disconnecting the power supply. Before the completion of the power down procedure, the module sends out the result code shown below:

NOTES NORMAL POWER DOWN 1. When unsolicited result codes do not appear when autobauding is active and DTE & DCE are not correctly synchronized after start-up, the module is recommended to be set to a fixed baud rate. 2. As network logout time is related to the local mobile network, it is recommended to delay about 12 seconds before disconnecting the power supply or restarting the module. After that moment, no further AT commands can be executed. Then the module enters the power down mode. Figure 17: Turn-off Timing by Using the PWRKEY Pin MC60_Hardware_Design Confidential / Released 42 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design 3.5.2.2. Power down Module Using AT Command It is also a safe way to turn off the module via AT command AT+QPOWD=1. This command will let the module log off from the network and allow the firmware to save important data before completely disconnecting the power supply. Before the completion of the power down procedure, the module sends out the result code shown below:

After that moment, no further AT commands can be executed. And then the module enters into the power down mode. Please refer to document [1] for details about the AT command AT+QPOWD. NORMAL POWER DOWN 3.5.2.3. Power down GNSS Part Alone Using AT Command It is a safe way to turn off the GNSS part alone via AT command AT+QGNSSC=0. The power down scenario for GNSS part is illustrated in the following figure. Figure 18: Turn-off Timing of GNSS Part by Using AT Command MC60_Hardware_Design Confidential / Released 43 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design 3.5.2.4. Under-voltage Automatic Shutdown The module will constantly monitor the voltage applied on the VBAT. If the voltage is 3.5V, the following URC will be presented:

UNDER_VOLTAGE WARNING The normal input voltage range is from 3.3V to 4.6V. If the voltage is <3.3V, the module will automatically shut down. If the voltage is <3.3V, the following URC will be presented:

UNDER_VOLTAGE POWER DOWN After that moment, no further AT commands can be executed. The module logs off from network and enters into power down mode. NOTE When unsolicited result codes do not appear when autobauding is active and DTE & DCE are not correctly synchronized after start-up, the module is recommended to be set to a fixed baud rate. 3.5.3. Restart Restart is a process of module power down first and then power on. The module can be restarted by driving the PWRKEY to a low level for a certain time, which is similar to the way of turning on the module but differs in the time for PWRKEY driving. In order to make the internal LDOs discharge completely after turning off the module, it is recommended to delay about 500ms before restarting the module. 3.6. Power on and down Scenarios in Stand-alone Solution In stand-alone solution, GSM and GNSS parts are controlled separately, and thus the power on and down control of them are independent from each other as well. The GSM part can be turned on/off or restarted via PWRKEY pin control, which is the same as that in all-in-one solution. The GNSS part is turned on/off via an external switch of MCU. 3.6.1. Power on GSM Part The GSM part can be turned on by driving the pin PWRKEY to a low level voltage. An open collector MC60_Hardware_Design Confidential / Released 44 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design driver circuit is suggested to control the PWRKEY. A simple reference circuit is illustrated in Figure 14. NOTES 1. The GSM module is set to autobauding mode (AT+IPR=0) by default. In the autobauding mode, URC RDY is not reported to the host controller after the module is powered on. When the GSM module is powered on after a delay of 4 or 5 seconds, it can receive AT command. Host controller should first send an AT string in order that the GSM module can detect baud rate of host controller, and it should continue to send the next AT string until receiving OK string from the module. Then enter AT+IPR=x;&W to set a fixed baud rate for the module and save the configuration to flash memory of the module. After these configurations, the URC RDY would be received from the UART Port of the GSM module every time when the module is powered on. For more details, refer to the section AT+IPR in document [1]. 2. When AT command is responded, it indicates the GSM module is turned on successfully; or else the module fails to be turned on. The other way to control the PWRKEY is through a button directly. While pressing the key, electrostatic strike may generate from the finger, and thus, a TVS component is indispensable to be placed nearby the button for ESD protection. For the best performance, the TVS component must be placed nearby the button. A reference circuit is shown in Figure15. The turn-on timing is illustrated in the following figure.

NORMAL POWER DOWN 3.7. Serial Interfaces The module provides four serial ports: UART Port, Debug Port, Auxiliary UART Port and GNSS UART Port. The module is designed as DCE (Data Communication Equipment), following the traditional DCE-DTE (Data Terminal Equipment) connection. Autobauding function supports baud rate from 4800bps to 115200bps. MC60_Hardware_Design Confidential / Released 47 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design The UART Port:

TXD: Send data to RXD of DTE. RXD: Receive data from TXD of DTE. RTS: Request to send. CTS: Clear to send. DTR: DTE is ready and inform DCE (this pin can wake the module up). RI: Ring indicator (when there is a call, SMS or URC output, the module will inform DTE with the RI pin). DCD: Data carrier detection (the validity of this pin demonstrates successful set-up of the communication link). The Debug Port:

DBG_TXD: Send data to the COM port of peripheral. DBG_RXD: Receive data from the COM port of peripheral. The Auxiliary UART Port:

In all-in-one solution:

TXD_AUX: Send data to the GNSS part. RXD_AUX: Receive data from the GNSS part. In stand-alone solution:

TXD_AUX: Keep open RXD_AUX: Keep open The GNSS UART Port In all-in-one solution:

GNSS_TXD: Send data to the GSM part. GNSS_RXD: Receive data from the GSM part. In stand-alone solution:

GNSS_TXD: Send GNSS data to the COM port of peripheral. GNSS_RXD: Receive GNSS data from the COM port of peripheral. The logic levels are described in the following table.

MC60_Hardware_Design Confidential / Released 49 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design 3.7.1. UART Port 3.7.1.1. Features of UART Port Seven lines on UART interface Contain data lines TXD and RXD, hardware flow control lines RTS and CTS, as well as other control lines DTR, DCD and RI. Used for AT command, GPRS data, etc. Multiplexing function is supported on the UART Port. NMEA output and PMTK command can be supported in all-in-one solution. Support the following communication baud rates:

300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, 115200bps. The default setting is autobauding mode. Support the following baud rates for autobauding function:

4800, 9600, 19200, 38400, 57600, 115200bps. Hardware flow control is disabled by default. When hardware flow control is required, RTS and CTS should be connected to the host. AT command AT+IFC=2,2 is used to enable hardware flow control. AT command AT+IFC=0,0 is used to disable the hardware flow control. For more details, please refer to document [1]. After setting a fixed baud rate or autobauding, please send AT string at that rate. The UART port is ready when it responds OK. Autobauding allows the module to detect the baud rate by receiving the string AT or at from the host or PC automatically, which gives module flexibility without considering which baud rate is used by the host controller. Autobauding is enabled by default. To take advantage of the autobauding mode, special attention should be paid according to the following requirements:

Synchronization between DTE and DCE:

When DCE (the module) is powered on with autobauding enabled, it is recommended to wait 2 to 3 seconds before sending the first AT character. After receiving the OK response, DTE and DCE are correctly synchronized. If the host controller needs URC in the mode of autobauding, it must be synchronized firstly. Otherwise the URC will be discarded. Restrictions on autobauding operation:

The UART port has to be operated at 8 data bits, no parity and 1 stop bit (factory setting). The At and aT commands cannot be used. Only the strings AT or at can be detected (neither At nor aT). The Unsolicited Result Codes like RDY, +CFUN: 1 and +CPIN: READY will not be indicated when the module is turned on with autobauding enabled and not be synchronized. Any other Unsolicited Result Codes will be sent at the previous baud rate before the module detects MC60_Hardware_Design Confidential / Released 50 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design the new baud rate by receiving the first AT or at string. The DTE may receive unknown characters after switching to a new baud rate. It is not recommended to switch to autobauding from a fixed baud rate. If autobauding is active it is not recommended to switch to multiplex mode. NOTE To assure reliable communication and avoid any problems caused by undetermined baud rate between DCE and DTE, it is strongly recommended to configure a fixed baud rate and save it instead of using autobauding after start-up. For more details, please refer to the Section AT+IPR in document [1]. 3.7.1.2. The Connection of UART The connection between module and host using UART Port is very flexible. Three connection styles are illustrated as below. A reference design for Full-Function UART connection is shown as below when it is applied in modulation-demodulation. Figure 21: Reference Design for Full-Function UART Three-line connection is shown as below. MC60_Hardware_Design Confidential / Released 51 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design Figure 22: Reference Design for UART Port (Three Line Connection) A reference design for UART Port with hardware flow control is shown as below. The connection will enhance the reliability of the mass data communication. Figure 23: Reference Design for UART Port with Hardware Flow Control 3.7.1.3. Firmware Upgrade TXD and RXD can be used for firmware upgrade in both all-in-one solution and stand-alone solution. The PWRKEY pin must be pulled down before firmware upgrade. A reference circuit is shown as below:

MC60_Hardware_Design Confidential / Released 52 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design Figure 24: Reference Design for Firmware Upgrade NOTE 1. In stand-alone solution, make sure the Auxiliary UART Port is connected to the GNSS UART Port before firmware upgrade. So it is recommended to retain this firmware upgrade circuit in design. 2. The firmware of module might need to be upgraded due to a certain reasons. It is thus recommended to reserve these pins in the host board for firmware upgrade. 3.7.2. Debug Port Two lines: DBG_TXD and DBG_RXD. The port outputs log information automatically. Debug Port is only used for firmware debugging and its baud rate must be configured as 460800bps. Figure 25: Reference Design for Debug Port MC60_Hardware_Design Confidential / Released 53 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design 3.7.3. Auxiliary UART Port and GNSS UART Port 3.7.3.1. Connection in All-in-one Solution In all-in-one solution, the Auxiliary UART Port and GNSS UART Port should be connected together, thus allowing for communication between GSM and GNSS parts. A reference design is shown below. Figure 26: Auxiliary and GNSS UART Port Connection in All-in-one Solution NOTE As the GNSS part of MC60 module outputs more data than a single GNSS system, the default output NMEA types running in 4800bps baud rate and 1Hz update rate will lose some data. The solution to avoid losing data in 4800bps baud rate and 1Hz update rate is to decrease the output NMEA types. 115200bps baud rate is enough to transmit GNSS NMEA in default settings and it is thus recommended. 3.7.3.2. Connection in Stand-alone Solution In stand-alone solution, the GNSS UART Port is connected to the COM port of peripheral, and the Auxiliary UART Port is recommended to keep open. MC60_Hardware_Design Confidential / Released 54 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design Figure 27: Auxiliary and GNSS UART Port Connection in Stand-alone Solution 3.7.4. UART Application A reference design of 3.3V level match is shown as below. If the host is a 3V system, please change the 5.6K resistors to 10K ones. Figure 28: Level Match Design for 3.3V System NOTE It is highly recommended to add the resistor divider circuit on the UART signal lines when the hosts level is 3V or 3.3V. For a higher voltage level system, a level shifter IC could be used between the host and the module. For more details about UART circuit design, please refer to document [13]. The following figure shows a sketch map between the module and the standard RS-232 interface. As the electrical level of module is 2.8V, a RS-232 level shifter must be used. Note that you should assure the I/O voltage of level shifter which connects to module is 2.8V.

An electret microphone is usually used. AIN are differential input channels. AOUT1 is used for output of receiver. The channel is typically used for building a receiver into a handset. AOUT1 channel is a differential channel. AOUT2 is used for loudspeaker output as it is embedded with an amplifier of class AB whose maximum drive power is 870mW. AOUT2 is a differential channel. AOUT2 also can be used for output of earphone, and can be used as a single-ended channel. LOUDSPKP and AGND can establish a pseudo differential mode. All these audio channels support voice and ringtone output, and so on, and can be switched by AT+QAUDCH command. For more details, please refer to document [1]. Use AT command AT+QAUDCH to select audio channel:

0--AIN/AOUT1, the default value is 0. 1--AIN/AOUT2, this channel is always used for earphone. 2--AIN/AOUT2, this channel is always used for loudspeaker. For each channel, you can use AT+QMIC to adjust the input gain level of microphone. You can also use AT+CLVL to adjust the output gain level of receiver and speaker. AT+QSIDET is used to set the side-tone gain level. For more details, please refer to document [1]. Table 16: AOUT2 Output Characteristics Item Condition Min. 8ohm load VBAT=4.2v THD+N=1%

Decrease TDD Noise and Other Noise The 33pF capacitor is applied for filtering out 900MHz RF interference when the module is transmitting at EGSM900MHz. Without placing this capacitor, TDD noise could be heard. Moreover, the 10pF capacitor here is used for filtering out 1800MHz RF interference. However, the resonant frequency point of a capacitor largely depends on the material and production technique. Therefore, customers would have to discuss with their capacitor vendors to choose the most suitable capacitor for filtering out EGSM900MHz, DCS1800MHz. The severity degree of the RF interference in the voice channel during GSM transmitting period largely depends on the application design. In some cases, EGSM900 TDD noise is more severe; while in other cases, DCS1800 TDD noise is more obvious. Therefore, you can have a choice based on test results. Sometimes, even no RF filtering capacitor is required. The capacitor which is used for filtering out RF noise should be close to the audio interface. Audio alignment should be as short as possible. In order to decrease radio or other signal interference, the position of RF antenna should be kept away from audio interface and audio alignment. Power alignment and audio alignment should not be parallel, and power alignment should be far away from audio alignment. The differential audio traces must be routed according to the differential signal layout rule. 3.8.2.

In order to enhance the reliability and availability of the SIM card in application, please conform to the following criteria in the SIM circuit design:

Keep layout of SIM card as close to the module as possible. Assure the trace length is less than 200mm. Keep SIM card signal away from RF and VBAT alignment. Assure the ground between module and SIM cassette short and wide. Keep the width of ground no less than 0.5mm to maintain the same electric potential. The decouple capacitor of SIM_VDD is less than 1uF and must be near to SIM cassette. To avoid cross talk between SIM_DATA and SIM_CLK, keep them away from each other and shield them with surrounded ground. In order to offer good ESD protection, it is recommended to add a TVS diode array. For more information of TVS diode, please visit http://www.onsemi.com/. The most important rule is to place the ESD protection device close to the SIM card socket and make sure the nets being protected will go through the ESD device first and then lead to module. The 22 resistors should be connected in series between the module and the SIM card so as to suppress the EMI spurious transmission and enhance the ESD protection. Please note that the SIM peripheral circuit should be close to the SIM card socket. Place the RF bypass capacitors (33pF) close to the SIM card on all signals lines to improve EMI suppression performance.

EASY Autonomous AGPS Technology Supplying aiding information like ephemeris, almanac, rough last position, time and satellite status, can help improve the acquisition sensitivity and the TTFF for a module. This is called as EASY technology and MC60s GNSS part supports it. EASY technology works as embedded software which can accelerate TTFF by predicting satellite navigation messages from received ephemeris. The GNSS part will calculate and predict orbit information automatically up to 3 days after first receiving the broadcast ephemeris, and save the predicted information into the internal memory. GNSS part of MC60 will use the information for positioning if no enough information from satellites, so the function is helpful for positioning and TTFF improvement. The EASY function can reduce TTFF to 5s in warm start. In this case, GNSSs backup domain should be valid. In order to gain enough broadcast ephemeris information from GNSS satellites, the GNSS part should receive the information for at least 5 minutes in good signal conditions after it fixes the position. EASY function is enabled by default. Command $PMTK869,1,0*34 can be used to disable EASY function. For more details, please refer to document [2]. NOTE In all-in-one solution, make sure the GNSS part is powered on before sending the PMTK command. 3.14. EPO Offline AGPS Technology MC60 module features a function called EPO (Extended Prediction Orbit) which is a world leading technology. When MC60 module is powered on, EPO function can be enabled via AT command AT+QGNSSEPO=1. When the GSM part detected that the EPO data has expired, the EPO data will be automatically downloaded to the GSM parts FS from MTK server via GSM/GPRS network; and the GNSS part will get the EPO data via build-in GNSS command from GSM's FS when it detected that the local EPO data has expired. When there is no local EPO data or when the data has expired, MC60 module will download the data (4KB) for 6 hours orbit predictions in order to achieve cold start in the shortest time, and then continue to download the EPO data (48KB) for 3 days. The technology allows the module to realize fast positioning. Command AT+QGNSSEPO=0 can turn off the EPO function. NOTE Make sure the EPO function is enabled if you need to download the EPO data. MC60_Hardware_Design Confidential / Released 68 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design 3.15. Multi-tone AIC MC60 module has a function called multi-tone AIC (Active Interference Cancellation) to decease harmonic of RF noise from Wi-Fi, GSM, 3G and 4G. Up to 12 multi-tone AIC embedded in the module can provide effective narrow-band interference and jamming elimination. The GNSS signal could be demodulated from the jammed signal, which can ensure better navigation quality. AIC function is enabled by default. Enabling AIC function will increase current consumption by about 1mA @VCC=3.3V. The following commands can be used to set AIC function. Enable AIC function: $PMTK 286,1*23 Disable AIC function: $PMTK 286,0*22 NOTE In all-in-one solution, make sure the GNSS part is powered on before sending these PMTK commands. MC60_Hardware_Design Confidential / Released 69 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design 4 Antenna Interface MC60 has two antenna interfaces: GSM antenna and GNSS antenna. The Pin 41 is the GSM antenna pad. The Pin 15 is the GNSS antenna pad. The RF interface of the two antenna pads has an impedance of 50. 4.1. GSM Antenna Interface There is a GSM antenna pad named RF_ANT for MC60. Table 24: Pin Definition of the RF_ANT Pin Name GND RF_ANT GND 4.1.1. Reference Design Pin No. 40 41 42 Description Ground GSM antenna pad Ground The external antenna must be matched properly to achieve the best performance; so the matching circuit is necessary. A reference design for GSM antenna is shown below. Figure 42: Reference Design for GSM Antenna MC60_Hardware_Design Confidential / Released 70 / 99 GSM/GPRS/GNSS Module Series MC60 Hardware Design MC60 provides an RF antenna pad for antenna connection. The RF trace in host PCB connected to the modules RF antenna pad should be coplanar waveguide line or microstrip line, whose characteristic impedance should be close to 50. MC60 comes with grounding pads which are next to the antenna pad in order to give a better grounding. Besides, a type matching circuit is suggested to be used to adjust the RF performance. To minimize the loss on RF trace and RF cable, please pay attention to the design. The following table shows the requirement on GSM antenna.

Figure 44: Reference Design with Active Antenna C1, R1 and C2 are reserved matching circuit for antenna impedance modification. By default, C1 and C2 are not mounted; R1 is 0 ohm. The external active antenna is powered by GNSS_VCC. The voltage ranges from 2.8V to 4.3V, and the typical value is 3.3V. If the voltage does not meet the requirements for powering the active antenna, an external LDO should be used. The inductor L1 is used to prevent the RF signal from leaking into the GNSS_VCC pin and route the bias supply to the active antenna, and the recommended value of L1 is no less than 47nH. R2 can protect the whole circuit in case the active antenna is shorted to ground. NOTE In all-in-one solution, please note that the power supply of GNSS_VCC is controlled by the GSM part through AT command.
