If the voltage drop is below the minimum drop voltage, the module may shut down due to low voltage. Table 7:Minimum drop voltage Module minimum drop voltage(V) SIM7070G&SIM7070G-PCIE SIM7070E 3.0 3.2 The figure 6 shows the recommended circuit. Figure 6: Power supply application circuit In addition, for ESD protection, it is suggested to add a TVS diode near the VBAT PINs. These capacitors should be put as close as possible to VBAT pads. Also, users should keep VBAT trace on circuit board wider than 2 mm to minimize PCB tra ce impedance. Table 8: Recommended TVS diode list No. Manufacturer Part Number Package Prisemi Prisemi 1 2 3 PESDHC2FD4V5B DFN1006 PESDHC3D3V3U SOD323 DFN1006 WILLsemi ESD5651N-2/TR SIM7070 Series _User Manual _V1.01 25 2019-7-31 3.1.2 Recommended Power Supply Circuit Smart Machine Smart Decision If the supply voltage exceeds the supply range of VBAT, the buck circuit should be used to meet the demand of power supply. When choosing buck chip, besides considering the maximum current output capability of IC to meet the demand of SIM7070 Series, it is also necessary to consider the low static power consumption of IC in PSM mode. Figure 7:Power supply reference circuit 3.1.3 Voltage Monitor To monitor the VBAT voltage, the AT command AT+CBC can be used. AT command "AT+CBATCHK=1" can be used to enable the VBAT voltage monitoring function. When the VBAT voltage exceeds the preset alarm voltage range, a warning message will be reported through the AT port. When the VBAT voltage exceeds the preset shutdown voltage range, the module will automatically shut down. The default alarm voltage and shutdown voltage of the SIM7070 series are shown in Table 9.

SIM7070 Series _User Manual _V1.01 26 2019-7-31 3.2 Power on/Power off/Reset Function 3.2.1 Power on Smart Machine Smart Decision The PWTRKEY pin has a default voltage of 1.5V. SIM7070 Series can be powered on by briefly pulling the PWRKEY pin to ground. It is strongly recommended to put an ESD protection diode close to the PWRKEY pin, as it would strongly enhance the ESD performance of PWRKEY pin. The PWRKEY pin has its own reset function. The reset time is determined by the internal timer
(default is 12 seconds). After the PWRKEY is pulled low, the module will be reset after 12 seconds. Therefore, it is not recommended to connect PWRKEY to GND all the time in external circuit design. Please refer to the figure8 for the recommended reference circuit. Figure 8: Reference power on/off circuit The power-on scenarios are illustrated in the figure 9.

*Note: The STATUS pin can be used to detect whether module is powered on or not. When module has been powered on and firmware goes ready, STATUS will be high level, or else STATUS will still low level. 3.3 UART Interface SIM7070 Series can provide 3 channels serial ports:
One channel full-function serial port UART1, it can be used for AT command communication between the module and the peripheral MCU. One channel 2-wire serial port UART3, the default function after booting is GPIO. It can be configured as a UART function, but it cannot be used for AT command communication. It is only used as UART in DAM (Downloadable Application Module) application when secondary development. It can also be configured as a GNSS NMEA data output port. One channel serial port DEBUG_UART, the boot log will be output from hear during the system boot-up. The default function after booting is GPIO. It can be configured as a UART function, but it cannot be used for AT command communication. It is only used as UART in DAM (Downloadable Application Module) application when secondary development. When the UART port is used as the AT communication port, it supports high speed mode, the baud rate is up to 4Mbps. The communication baud rates include: 0, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 921600, 2000000, 3000000, 3200000 and 3686400 bps. The rate 0bps marks auto baud rate. And it supports auto baud rate, but the rate only supported on 9600, 19200, 38400, 57600, 115200. If users need to change to other baud rate, it needs to switch via manual operation.

The RI pin can be used to interrupt output signal to inform the host controller such as application CPU. Before that, users must use AT command AT+CFGRI=1 to enable this function. Normally RI will keep high level until certain conditions such as receiving SMS, or a URC report coming, then it will output a low level pulse 120ms, in the end, it will become high level. Figure 14: RI behaviourSMS and URC report The DTR pin description:
After setting the AT command AT+CSCLK=1, and then pulling up the DTR pin, Module will enter sleep mode when module is in idle mode. In sleep mode, the UART is unavailable. When SIM7070 Series enters sleep mode, pulling down DTR can wake up module. After setting the AT command AT+CSCLK=0, SIM7070 Series will do nothing when the DTR pin is pulling up. Note: For more details of AT commands about UART, please refer to document [1] and [20]. SIM7070 Series _User Manual _V1.01 31 2019-7-31 3.4 USB Interface Smart Machine Smart Decision SIM7070 Series has a USB2.0 interface, it can be used for software upgrade and software debugging. The USB of the SIM7070 series only supports slave mode and does not support USB charging. USB does not support Suspend mode, the module will not be able to enter the minimum power mode when USB is connected. USB_VBUS is the detecting signal for USB inserting. The input voltage range on the USB_VBUS pin is from 3.5V to 5.25V. If there is out of this range, it may be due to USB function unidentifiable, even damaging the module. The reference circuit refers to the following figure. Figure 15: USB reference circuit Because of the high speed on USB bus, more attention should be paid to the influence of the junction capacitance of the ESD component on USB data lines. Typically, the capacitance of the D1 and D2 should be less than 3pF. D3 is suggested to select the diode with anti-ESD and voltage surge function, or customer could add a ZENER diode for surge clamping.

Figure 16: SIM interface reference circuit SIM_DATA has been pulled up with a 20K resistor to SIM_VDD in module, so it no need pulled up resistor anymore.SIM_VDD needs a 100nF capacitor close to SIM socket. SIM_CLK is very important signal, the rise time and fall time of SIM_CLK should be less than 40ns. So the junction capacity of the TVS need to less 50pF. In order to enhance the reliability and availability of the (U)SIM card in applications,Please follow the guidelines below when designing. It is recommended to place a 100nF capacitor on the SIM_VDD signal line close to the SIM card holder. SIM7070 Series _User Manual _V1.01 33 2019-7-31 Smart Machine Smart Decision Place TVS near the SIM card holder. The junction capacity of the TVS should not exceed 50pF. The 22 resistor in series between the SIM card holder and the module can enhance the ESD protection performance. Keep SIM card signals away from RF and VBAT traces. SIM card signal line traces to avoid branch. To avoid cross-talk between SIM_DATA and SIM_CLK, keep them away from each other and shield them with surrounded ground. USIM_RST should also be ground shielded. 3.6 PCM Interface Table 15: PCM format SIM7070 Series provides a PCM interface for external codec, which can be used in master mode with short sync and 16 bits linear format.

<0.5dB
<0.9dB
<1.2dB To facilitate the antenna tuning and certification test, a RF connector and an antenna matching circuit should be added. The following figure is the recommended circuit. Figure 26: Antenna matching circuit (MAIN_ANT) In above figure, the components R1, C1, C2 and R2 are used for antenna matching, the values of components can only be achieved after the antenna tuning and usually provided by antenna vendor. By default, the R1, R2 are 0 resistors, and the C1, C2 are reserved for tuning. The component D1 is a TVS for ESD protection, and it is optional for users according to application environment. The RF test connector is used for the conducted RF performance test, and should be placed as close as to the modules MAIN_ANT pin. The traces impedance between SIM7070 Series and antenna must be controlled in 50. Two TVS are recommended in the table below.

This solution performs well, even in very challenging environmental conditions where conventional GNSS receivers fail, and provides a platform to enable wireless operators to address both location-based services and emergency mandates. 4.3.1 GNSS Technical specification Tracking sensitivity: TBD dBm(GPS)/ TBD dBm(GLONASS)/TBD (BD)/TBD(Galileo) Cold-start sensitivity: TBD dBm Accuracy (Open Sky): TBD m (CEP50) TTFF (Open Sky) : Hot start < TBD s, Cold start< TBD s Receiver Type: 16-channel, C/A Code GPS L1 Frequency: 1575.421.023MHz GLONASS L1: 1598.0625 ~1605.375MHz BDS B1: 1559.052~1591.788MHz Galileo L1: 1575.421.023MHz Update rate: Default 1 Hz GNSS data format: NMEA-0183 GNSS Current consumption : TBD mA (GSM/LTE Sleep, in total on VBAT pins) GNSS antenna: Passive/Active antenna Note: If the antenna is active type, the power should be given by main board because there is no power supply on the GNSS antenna pad. If the antenna is passive, it is suggested that the external LNA should be used. 4.3.2 GNSS Application Guide Users can adopt an active antenna or a passive antenna to SIM7070 Series. If using a passive antenna, an external LNA is a must to get better performance. The following figures are the reference circuits. Figure 27: Active antenna circuit SIM7070 Series _User Manual _V1.01 47 2019-7-31 Smart Machine Smart Decision Figure 28: Passive antenna circuit (Default) In above figures, the components C1, L1 and L2 are used for antenna matching. Usually, the values of the components can only be achieved after antenna tuning and usually provided by antenna vendor. C2 is used for DC blocking. L3 is the matching component of the external LNA, and the value of L3 is determined by the LNA characteristic and PCB layout. Both VDD of active antenna and V_LNA need external power supplies which should be considered according to active antenna and LNA characteristic. LDO/DCDC is recommended to get lower current consuming by shutting down active antennas and LNA when GNSS is not working. GNSS can be tested by NMEA port. NMEA sentences can be obtained through UART or USB automatically. NMEA sentences include GSV, GGA, RMC, GSA, and VTG. Before using GNSS, user should configure SIM7070 Series in proper operating mode by AT command. Please refer to related documents for details. SIM7070 Series can also get position location information through AT directly. Note:
1. GNSS is closed by default and can be started by AT+CGNSPWR=1. The AT command has two parameters, the first is on/off, and the second is GNSS mode. Default mode is standalone mode. AGPS mode needs more support from the mobile telecommunication network. Please refer to document [21] for more details. 2. If the passive antenna is used, put the LNA close to the antenna. 3. Make sure there are no noise signals around GNSS antenna. SIM7070 Series _User Manual _V1.01 48 2019-7-31 Smart Machine Smart Decision 4.4 RF traces note 4.4.1 RF traces layout Keep the RF trace from module ant pin to antenna as short as possible RF trace should be 50 either on the top layer or in the inner layer RF trace should be avoided right angle and sharp angle. Put enough GND vias around RF traces. RF trace should be far away from other high speed signal lines. Figure 29: RF trace should be far away from other high speed signal lines Avoiding the paroling rout of other system antennas nearly. There should be some distance from The GND to the inner conductor of the SMA connector. It is better to keep out all the layers from inner to the outer conductor. Figure 30: The distance between GND to the inner conductor of SMA GND pads around the ANT pad should not be hot pad to keep the GND complete.

Sleep Idle Standby N o r m a l o p e r a t i o n In this case, the current consumption of module will be reduced to the minimal level and the module can still receive paging message and SMS. Software is active. Module is registered to the network, and the module is ready to communicate. Cat-M1 Voice Call Connection between two subscribers is in progress. In this case, the power consumption depends on network settings. Module is ready for data transmission, but no data is currently sent or received. In this case, power consumption depends on network settings. There is data transmission in progress. In this case, power consumption is related to network settings (e.g. power control level);
uplink/downlink data rates, etc. Data transmission SIM7070 Series _User Manual _V1.01 52 2019-7-31 Minimum functionality mode Flight mode Power Saving Mode (PSM) Smart Machine Smart Decision AT command AT+CFUN=0 and AT+CSCLK=1 can be used to set the module to a minimum functionality mode without removing the power supply. In this mode, the RF part of the module will not work and the SIM card will not be accessible, but the serial port and USB port are still accessible. The power consumption in this mode is lower than normal mode. AT command AT+CFUN=4 can be used to set the module to flight mode without removing the power supply. In this mode, the RF part of the module will not work, but the serial port and USB port are still accessible. The power consumption in this mode is lower than normal mode. Setting AT command AT+CPSMS=1 can be enable the PSM mode. In this mode, The mode is similar to power-off. But the module remains registered on the network and there is no need to re-attach or re-establish the network connections. And all of the functions will be unavailable except the RTC function. PWRKEY and timer expires can wake up the module. Extended
(e-DRX) Mode DRX In idle or sleep mode, module and the network may negotiate over non-access stratum signaling the use of extended mode DRX for reducing power consumption. 5.3.2 Sleep mode Module can enter into sleep mode for reducing its power consumption in idle module. In sleep mode, the current consumption of module will be reduced to very small level, and module can still receive paging message and SMS. Several hardware and software conditions must be satisfied together in order to let SIM7070 Series enter sleep mode:
USB condition: Connected USB cant enter into sleep mode. So if module wants to enter into sleep mode, it must disconnect the power supply for USB_VBUS first. Software condition: If module wants to enter into sleep mode, AT comment AT+CSCLK=1 must be set to close some clock in the module. If the value AT+CSCLK is 0, module will never enter into sleep mode. UART condition: If module wants to enter into sleep mode, AT comment AT+CSCLK=1 must be set to close some clock in the module. If the value AT+CSCLK is 0, module will never enter into sleep mode. If it meets all the conditions at the same time, module will enter into sleep mode. In sleep mode, the UART is unavailable. If the host need to communicate with module, it need to pull down DTR can wake up module. SIM7070 Series _User Manual _V1.01 53 2019-7-31 5.3.3 Minimum functionality mode and Flight mode Smart Machine Smart Decision Minimum functionality mode ceases a majority function of the module, thus minimizing the power consumption. This mode is set by the AT command which provides a choice of the functionality levels. AT+CFUN=0: Minimum functionality AT+CFUN=1: Full functionality (Default) AT+CFUN=4: Flight mode If SIM7070 Series has been set to minimum functionality mode, the RF function and SIM card function will be closed. In this case, the serial port and USB are still accessible, but RF function and SIM card will be unavailable. If SIM7070 Series has been set to flight mode, the RF function will be closed. In this case, the serial port and USB are still accessible, but RF function will be unavailable. When SIM7070 Series is in minimum functionality or flight mode, it can return to full functionality by the AT command AT+CFUN=1. 5.3.4 Power Saving Mode (PSM) SIM7070 Series module can enter into PSM for reducing its power consumption. The mode is similar to power-off, but the module remains registered on the network and there is no need to re-attach or re-establish the network connections. So in PSM all the functions will be unavailable except the RTC function, module cannot immediately respond users requests. When the module wants to use the PSM, it can be enabled via AT+CPSMS=1 command. The command takes effect after module reboot. If the network supports PSM and accepts that the module uses PSM, the network confirms usage of PSM by allocating an Active Time value to the module. Module will be into PSM according to the command from network. Either of the following methods will wake up the module from PSM:
Pulling PWRKEY pin to low level will wake up the module. When the timer expires, the module will be automatically woken up. 5.3.5 Extended Mode DRX (e-DRX) In idle or sleep mode, module and the network may negotiate over non-access stratum signaling the use of extended mode DRX for reducing power consumption. E-DRX diagrammatic sketch refer to the following figure. SIM7070 Series _User Manual _V1.01 54 2019-7-31 ptw ptw ptw Smart Machine Smart Decision DRX DRX DRX Cycle length Cycle length Cycle length Figure 31: e-DRX diagrammatic sketch When module and the network negotiate stratum signaling in idle mode or sleep mode, extended mode DRX can decrease the times of paging time window (PTW) and increase the cycle length. For this reason it had reduced the times of DRX, and had reduced the frequency of DRX between module and the network. So that can reduce power consumption for module. If e-DRX is supported by the network, then it can be enabled by AT+CEDRXS command. Note: For details about AT+CEDRXS, please refer to Document [1]

Safety Caution Table 48: Safety Caution Marks Requirements When in a hospital or other health care facility, observe the restrictions about the use of mobiles. Switch the cellular terminal or mobile off, medical equipment may be sensitive and not operate normally due to RF energy interference. 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 to prevent interference with communication systems. Forgetting to think much of these instructions may impact the flight safety, or offend local legal action, or both. Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard. Your cellular terminal or mobile receives and transmits radio frequency energy while is used close to TV sets, radios, switched on. RF interference can occur if it computers or other electric equipment. Road safety comes first! Do not use a hand-held cellular terminal or mobile when driving a vehicle, unless it is securely mounted in a holder for hands free operation. Before making a call with a hand-held terminal or mobile, park the vehicle. GSM cellular terminals or mobiles operate over radio frequency signals and cellular networks and cannot be guaranteed to connect in all conditions, especially with a mobile fee or an invalid SIM card. While you are in this condition and need emergent help, please remember to use emergency calls. In order to make or receive calls, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength. Some networks do not allow for emergency call if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may have to deactivate those features before you can make an emergency call. Also, some networks require that a valid SIM card be properly inserted in the cellular terminal or mobile.
