On VBAT pads, when module works on CAT-M1 mode, the ripple current is up to 0.6A typically. For steady voltage, the power supply capability must be up to 0.5A. On VBAT pads, when module works on EDGE or GPRS mode, The ripple current is up to 2A typically. For steady voltage, the power supply capability must be up to 2A. in order to avoid the voltage dropped down more than 300mV, the load capacitor on VBAT pads must be up to 300uF. The figure 5shows the VBAT voltage ripple wave at the maximum power transmit phase in EDGE/GPRS emission mode.

If the VBAT voltage drops below the minimum input voltage, the module may shut down due to low voltage. Table 7: Minimum input voltage Module SIM7075G Minimum input voltage(V) 3.3 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 trace impedance. Table 8: Recommended TVS diode list Manufacturer Prisemi Prisemi WILLsemi Part Number PESDHC2FD4V5B PESDHC3D3V3U ESD5651N-2/TR Package DFN1006 SOD323 DFN1006 No. 1 2 3 NOTE 1. The customer's circuit design must have the function that the master can control the power off of the module. The module can be shut down or restarted normally. Only when the module is abnormal and cannot be shut down or restarted normally can the power be turned off. 2. When the module is working normally, do not cut off the power supply of the module VBAT directly to avoid damage to the internal flash of the module. It is strongly recommended to turn off the module through PWRKEY or AT command before disconnecting the module VBAT power. www.simcom.com 22 / 74 SIM7075G User Manual V1.00 3.1.2 Recommended Power Supply Circuit 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 SIM7075G, it is also necessary to consider the low static power consumption of IC in PSM mode. Figure 7: Power supply reference circuit 3.1.3Voltage 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 SIM7075G are shown in Table 9. Table 9: Alarm and Shutdown Voltage Range Low voltage shutdown(V) 2.9 Low voltage alarm(V) 3.1 High voltage shutdown(V) 4.65 High voltage alarm(V) 4.7 Module SIM7075G NOTE Under-voltage warning function and under-voltage power-off function are disabled by default.

SIM7075G 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 12.6 seconds). After the PWRKEY is pulled low, the module will be reset after 12.6 seconds. Therefore, it is not recommended to connect PWRKEY to GND all the time in external circuit design. Please refer to the following figure for the recommended reference circuit.

Before turning on the module, be sure to pay attention to the maximum conditions (such as voltage and temperature range) allowed by the module, otherwise exceeding the absolute maximum value of the module may cause permanent damage to the module. 4. The ESD protection diode junction capacitance on the PWR cannot exceed 10pF, otherwise the module may be turned on automatically. 3.2.2 Power off The following methods can be used to power offSIM7075G. Method 1: Power off SIM7075G by pulling the PWRKEY pin to ground. Method 2: Power off SIM7075G by AT command AT+CPOWD=1. Method 3: over-voltage or under-voltage automatic power off. The function can be enabled by AT command AT+CBATCHK=1. Default is disabled. NOTE For details about AT+CPOWD and AT+CBATCHK, please refer to Document [1]. It is not recommended to turn off the module by disconnecting VBAT power. Otherwise, there is a risk of damage to the module file system. These procedures will make modules disconnect from the network and allow the software to enter a safe state, and save data before module be powered off completely.

www.simcom.com 26 / 74 SIM7075G User Manual V1.00 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. 3.3.1 UART Design Guide The following figures show the reference design.

Figure 13: Reference circuit with level shifter IC www.simcom.com 28 / 74 SIM7075G User Manual V1.00 Figure 14: Reference circuit with Transistor NOTE When it uses the level shifter IC, the pull up resistance on TXD_3.3V, RTS_3.3V, DCD_3.3V and RI_3.3V should not be less than 47K. When it uses the transistor, the selection of the transistor must be a high-speed transistor, and the model MMBT3904 is recommended. 3.3.2 RI and DTR Behavior The RI pin description:
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 15: 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 enters sleep mode, pulling down DTR can wake up module. www.simcom.com 29 / 74 SIM7075G User Manual V1.00 After setting the AT command AT+CSCLK=0, SIM7075G 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]. 3.4 USB Interface SIM7075G has a USB2.0 interface. It can be used for software upgrade and software debugging. The USB of the SIM7075G 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 16: 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. www.simcom.com 30 / 74 SIM7075G User Manual V1.00 Table 13: Recommended TVS models No. Manufacturer Part Number Package 1 2 3 4 NXP Willsemi NXP Willsemi PESD5V0X1BCAL ESD5301N PESD5V0H1BSF ESD5311Z-2/TR 0402 0402 0201 0201 NOTE The USB interface is strongly recommended to reserve test points.

The following figure shows the 6-pin SIM card holder reference circuit. Figure 18: SIM interface reference circuit SIM_DATA has been pulled up with a 20KR 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. www.simcom.com 32 / 74 SIM7075G User Manual V1.00 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. 3.7 PCM Interface SIM7075G provides a PCM interface for external codec, which can be used in master mode with short sync and 16 bits linear format.

SIMCom recommends that the total insertion loss between the antenna pads and antennas should meet the following requirements:
Table 28: Trace loss Frequency 700MHz-960MHz 1710MHz-2170MHz 2300MHz-2650MHz Loss
<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. www.simcom.com 42 / 74 SIM7075G User Manual V1.00 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 SIM7075G and antenna must be controlled in 50. Two TVS are recommended in the table below. Table 29: Recommended TVS Package Part Number 0201 0402 CE0201S05G01R PESD0402-03 4.3 GNSS Vender PRISIMI SIM7075G merges GNSS (GPS/GLONASS/BD/Galileo) satellite and network information to provide a high-availability solution that offers industry-leading accuracy and performance. 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: -159 dBm (GPS+GLONASS)/-159 dBm (GPS+BD) Cold-start sensitivity: -147.5 dBm Accuracy (Open Sky): 0.4 m(GPS+BD) TTFF (Open Sky) : Hot start < 1 s, Cold start< 31 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 www.simcom.com 43 / 74 SIM7075G User Manual V1.00 Galileo L1:1575.421.023MHz Update rate: Default 1 Hz GNSS data format: NMEA-0183 GNSS Current consumption :54mA (AT+CFUN=0,without USB) 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 SIM7075G. 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 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 www.simcom.com 44 / 74 SIM7075G User Manual V1.00 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 SIM7075G in proper operating mode by AT command. Please refer to related documents for details. SIM7075G 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. 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. www.simcom.com 45 / 74 SIM7075G User Manual V1.00 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. www.simcom.com 46 / 74 SIM7075G User Manual V1.00 4.4.2 LTE ANT and other system ANT decoupling Make sure the efficiency of LTE main ANT more than 40%
Keep the decoupling of LTE main ANT to WLAN ANT more than 15dB Keep the decoupling of LTE main ANT to GNSS ANT more than 30dB NOTE The decoupling value can be provided by ANT adventure.

The performance will be reduced slightly from the 3GPP specifications if the temperature is outside the normal operating temperature range and still within the extreme operating temperature range. 5.3 Operating Mode 5.3.1 Operating Mode Definition The table below summarizes the various operating modes of SIM7075G product. Table 35: Operating mode Definition Mode Function Sleep Idle Normal operation Cat-M1 Voice Call Standby Data transmission Minimum functionality mode Flight mode Power Saving Mode (PSM) www.simcom.com 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. 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. AT command AT+CFUN=0 and AT+CSCLK=1can 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=4can 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. 50 / 74 SIM7075G User Manual V1.00 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. 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. Extended Mode DRX (e-DRX) 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 SIM7075G 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. 5.3.3 Minimum functionality mode and Flight mode 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 SIM7075G 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 SIM7075G 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. www.simcom.com 51 / 74 When SIM7075G is in minimum functionality or flight mode, it can return to full functionality by the AT command AT+CFUN=1. SIM7075G User Manual V1.00 5.3.4 Power Saving Mode (PSM) SIM7075G 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. ptw ptw ptw DRX DRX DRX Cyclelength Cyclelength Cyclelength 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. www.simcom.com 52 / 74 If e-DRX is supported by the network, then it can be enabled by AT+CEDRXS command.
