Smart Machine Smart Decision SIM7100A_User Manual_V1.01 2014-12-11 25 3 Application Interface Specification 3.1 Power Supply The power supply pins of SIM7100A include four VBAT pins (pin 62&63, pin 38&39). VBAT directly supplies the power to RF and baseband circuit. VBAT directly supplies the power to RF PA and baseband system. Power Supply Pin 4 VBAT pins are dedicated to connect the supply voltage. Table 7: VBAT Pin description Pin type Pin name Min Typ Max Unit POWER VBAT 3.15 3.8 4.2 V 3.1.1 Design Guide Make sure that the input voltage at the VBAT pin will never drop below 3.15V even during a transmit when the current consumption up to more than 700mA. If the power voltage drops below 3.15V, the module may be shut down automatically. Using large tantalum capacitors (above 300uF) will be the best way to reduce the voltage drops. For the consideration of RF performance and system stability, some multi-layer ceramic chip (MLCC) capacitors (0.1/1uF) need to be used for EMC because of their low ESR in high frequencies. Note that capacitors should be put beside VBAT pins as close as possible. Also User should minimize the PCB trace impedance from the power supply to the VBAT pins through widening the trace to 80 mil or more on the board. The following figure is the recommended circuit. Figure 7: VBAT input application circuit Note: The Cd, Ce, Cb, Cc and Cf must be mounted for SIM7100A.For SIM5360 the Ca, Cb ,Ce, Cc and
Smart Machine Smart Decision SIM7100A_User Manual_V1.01 2014-12-11 26Cf must be mounted. In addition, in order to get a stable power source, it is suggested to use a zener diode of which reverse zener voltage is 5.1V and dissipation power is more than 500mW. Table 8: Recommended zener diode models No. Manufacturer Part Number Power Package 1 On semi MMSZ5231BT1G 500mW SOD123 2 Prisemi PZ3D4V2H 500mW SOD323 3 Vishay MMSZ4689-V 500mW SOD123 4 Crownpo CDZ55C5V1SM 500mW 0805 3.1.2 Recommended Power supply circuit We recommend DCDC or LDO is used for the power supply of the module, make sure that the peak current of power components can rise up to more than 2A. The following figure is the reference design of +5V input power supply. The designed output for the power supply is 3.8V, here a linear regulator can be used. Figure 8: Reference circuit of the LDO power supply If there is a big difference between the input voltage and the desired output (VBAT), a switching converter power will be preferable because of its better efficiency, especially at the high current situation. The following figure is the reference circuit. Note that DCDC may deprave RF performance because of ripple current intrinsically.
Smart Machine Smart Decision SIM7100A_User Manual_V1.01 2014-12-11 27 Figure 9: Reference circuit of the DCDC power supply 3.1.3 Vol tage monitor To monitor the power supply voltage, user can use the AT command “AT+CBC”, this command has two parameters: the battery status and the voltage value (mV). It will return the capacity percentage and actual value of battery (at the VBAT pin). The voltage is continuously measured at intervals, whenever the measured battery voltage is lower than a specific value set by the AT command “AT+CVALARM”. For example, if the voltage value is set to be 3.4V, the following URC will be presented: “warning! voltage is low: 3.3v”. If the voltage is lower than a specific value which is set by the AT command “AT+CPMVT”, the module will be powered off automatically and AT commands cannot be executed any more. Note: Under-voltage warning function and under-voltage power-off function are disabled by default. For more information about these AT command, please refer to Document [1]. 3.2 Power on/Power off/Reset Time Sequence 3.2.1 Power on Sequence SIM7100A can be powered on by PWRKEY pin, which starts normal operating mode. PWRKEY pin is pulled up with a 200k ohm resistor to 1.8V in module. User can power on the SIM7100A by pulling the PWRKEY pin down for a short time. The power-on scenarios are illustrated in the following figures.

When module is powered on and firmware goes ready, VDD_EXT will be high level. Note: For details about “AT+CPOF”, please refer to Document [1]. 3.2.3 Reset Function SIM7100A also have a RESET pin (PIN4) to reset the module. This function is used as an emergency reset

User can pull the RESET pin to ground, then the module will reset. This pin is already pulled up in module, so the external pull-up resistor is not necessary. A 100nF capacitor close to the RESET pin is strongly recommended. A reference circuit is recommended in the following figure. Figure 12: Reset circuit Note：50ms<Treset<200ms.

Normally it will keep high logic level until certain condition such as receiving SMS, voice call (CSD, video) or URC reporting, then “RI” will change to low logic level to inform the master (client PC). It will stay low until the master clears the interrupt event with AT command. Figure 13: RI behaviour in NULL Modem
Smart Machine Smart Decision SIM7100A_User Manual_V1.01 2014-12-11 33 If Full Modem is used to establish communication between devices, the pin “RI” is another operation status. Initially it keeps high, when a voice call or CSD call comes, the pin “RI” will change to low for about 5900ms, then it will return to high level for 100ms. It will repeat this procedure until this call is answered or hung up. Figure 14: RI behaviour in FULL Modem 3.3.2 Design Guide The application circuit is in the following figures.

The PCM interface enables communication with an external codec to support hands-free applications. SIM7100A PCM interface can be used in two modes: the default mode is auxiliary PCM (8 KHz long sync mode at 128 KHz PCM CLK); the other mode is primary PCM (8 KHz short sync mode at 2048 KHz PCM CLK). In short-sync (primary PCM) mode, SIM7100A can be a master or a slave. In long-sync (auxiliary PCM) mode,
Smart Machine Smart Decision SIM7100A_User Manual_V1.01 2014-12-11 39SIM7100A is always a master. SIM7100A also supports 3 kinds of coding formats: 8 bits (-law or A-law) and 16 bits (linear). Note: PCM interface is multiplexed from GPIO (default setting). The AT command “AT+CPCM” is used to switch between PCM and GPIO functions. Please refer to document [21] and document [1] for details. 3.6.1 PCM Pin Description Table 18: PCM Pin description Pins Pin No. Description PCM_OUT 73 PCM data output PCM_IN 74 PCM data input PCM_SYNC 75 PCM data synchrony PCM_CLK 76 PCM data clock Table 19: PCM Electronic characteristic Symbol Parameter Min Typ Max Unit VIH High-level input voltage 1.26 1.8 2.1 V VIL Low-level input voltage -0.3 0 0.63 V VOH High-level output voltage 1.35 - 1.8 V VOL Low-level output voltage 0 0 0.45 V 3.6.2 PCM Signal Description The default PCM interface in SIM7100A is the auxiliary PCM interface. The data changes on the high level of PCM_CLK and is sampled at the falling edge of PCM_CLK in one period. Primary PCM is disabled after every power-on or every reset event. So user must use AT command to enable the primary PCM mode after powering on or resetting the module every time if user wants to use Primary PCM.SIM7100A PCM Interface can be operated in Master or Slave mode if it is configured to primary PCM. In Master Mode, the Module drives the clock and sync signals that are sent to the external codec. When it is in Slave Mode, the external codec drives the clock and sync signals which are sent to the module. Both PCM modes are discussed in this section followed by additional PCM topics.
Smart Machine Smart Decision SIM7100A_User Manual_V1.01 2014-12-11 403.6.3 Auxiliary PCM (128 KHz PCM clock) -law coding is supported by the auxiliary PCM.

Customer’s antenna should be located in the host board and connected to module’s antenna pad through micro-strip line or other types of RF trace and the trace impedance must be controlled in 50Ω. The maximum gain of the LTE B2/WCDMA B2 antenna gain should not exceed 3.4dBi, LTE B4 antenna gain should not exceed 1.9 dBi, LTE B5/WCDMA B5 antenna gain should not exceed 2.8 dBi, LTE B17 antenna gain should not exceed 1dBi considering the SAR radio. SIMCom recommends that the total insertion loss between the antenna pad and antenna should meet the following requirements. No antenna gain may be used that would exceed the 2W EIRP power limit in 1900MHz band.The input impendence of the antenna should be 50Ω, and the VSWR should be less than 2. ● WCDMA 2100/1900<0.9dB ● WCDMA 900/850<0.5 dB ● LTE (F<1GHz) <0.5dB ● LTE (1GHz<F<2GHz) <0.9dB ● LTE (2GHz<F) <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.

Smart Machine Smart Decision SIM7100A_User Manual_V1.01 2014-12-11 604.3.2 GNSS Operate Mode SIM7100A supports both A-GPS and S-GPS, and then provides three operating modes: mobile-assisted mode, mobile-based mode and standalone mode. A-GPS includes mobile-assisted and mobile-based mode. In mobile-assisted mode, when a request for position location is issued, available network information is provided to the location server (e.g. Cell-ID) and assistance is requested from the location server. The location server sends the assistance information to the handset. The handset/mobile unit measures the GNSS observables and provides the GNSS measurements along with available network data (that is appropriate for the given air interface technology) to the location server. The location server then calculates the position location and returns results to the requesting entity. In mobile-based mode, the assistant data provided by the location server encompasses not only the information required to assist the handset in measuring the satellite signals, but also the information required to calculate the handset’s position. Therefore, rather than provide the GNSS measurements and available network data back to the location server, the mobile calculates the location on the handset and passes the result to the requesting entity. In standalone (autonomous) mode, the handset demodulates the data directly from the GNSS satellites. This mode has some reduced cold-start sensitivity, and a longer time to first fix as compared to the assisted modes. However, it requires no server interaction and works out of network coverage. This combination of GNSS measurements and available network information provides: ● High-sensitivity solution that works in all terrains: Indoor, outdoor, urban, and rural ● High availability that is enabled by using both satellite and network information Therefore, while network solutions typically perform poorly in rural areas and areas of poor cell geometry/density, and while unassisted, GNSS-only solutions typically perform poorly indoors. The SIM7100A GNSS solution provides optimal time to fix, accuracy, sensitivity, availability, and reduced network utilization in both of these environments, depending on the given condition. 4.3.3 GNSS Application Guide Users can adopt an active antenna or a passive antenna as GNSS signal transceiver. In this document, all GNSS specification mentioned is from passive antenna. The following is the reference circuit.

In active antenna circuit, users must use an external LDO/DCDC to provide VDD voltage whose value should be taken according active antenna characteristic, and VDD can be shut down to avoid consuming additional current when not being used. GNSS can be used by NMEA port. User can select NMEA as output through UART or USB. NMEA sentences are automatic and no command is provided. NMEA sentences include GSV, GGA, RMC, GSA, and VTG. Before using GNSS, user should configure SIM7100A in proper operating mode by AT command. Please refer to related document for details. SIM7100A can also get position location information through AT directly.
Smart Machine Smart Decision SIM7100A_User Manual_V1.01 2014-12-11 62Note: GNSS is closed by default, it could be started by AT+CGPS. 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. Refer to AGPS application document for details.

Temperatures outside of the range -30℃ ~ +80℃ might slightly deviate from ETSI specifications. Functional: the module is able to make and receive voice calls, data calls, SMS and make GPRS/WCDMA/HSPA+ traffic.
Smart Machine Smart Decision SIM7100A_User Manual_V1.01 2014-12-11 645.2 Operating Mode 5.2.1 Operating Mode The table below summarizes the various operating modes of SIM7100Ax. Table 46: Operating mode Mode Status Function Normal operation Sleep WCDMA /LTE Module will automatically go into sleep mode if the conditions of sleep mode are enabling and there is no on air and no hardware interrupt (such as USB wake-up operation or data on serial port). In this case, the current consumption of module will be reduced to the minimal level. In sleep mode, the module can still receive paging message and SMS. Idle WCDMA/LTE Software is active. Module is registered to the WCDMA/LTE network, and the module is ready to communicate. Talk WCDMA Connection between two subscribers is in progress. In this case, the power consumption depends on network settings such as DTX off/on, FR/EFR/HR, hopping sequences, antenna. Standby EDGE/HSPA+/LTE Module is ready for EDGE/HSPA+ /LTE data transfer, but no data is currently sent or received. In this case, power consumption depends on network settings and EDGE/HSPA+ /LTE configuration. Data transfer HSPA+ /LTE There is EDGE/HSPA+/LTE data transfer in progress. In this case, power consumption is related to network settings (e.g. power control level); uplink/downlink data rates and GPRS configuration (e.g. used multi-slot settings). Minimum functionality mode AT command “AT+CFUN” 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 or the USIM card will not be accessible, or both RF part and USIM card will be closed, and the serial port is still accessible. The power consumption in this mode is lower than normal mode. 5.2.2 Minimize Power Consumption There are two modes that SIM7100A achieves low power consumption.
Smart Machine Smart Decision SIM7100A_User Manual_V1.01 2014-12-11 655.2.3 Sleep mode If peripheral equipments stops working, and there is no on air or hardware interrupts (such as GPIO interrupts or data on UART), SIM7100A will enter sleep mode automatically. In this mode, SIM7100A can still receive paging，voice call or SMS from network. If USB interface of SIM7100A is connected to host CPU, but host CPU does not support USB suspending, then SIM7100A will not enter sleep mode. After USB is disconnected, SIM7100A will enter sleep mode. Note: When UART interface is connected with host CPU, SIM7100A cannot enter sleep mode until RXD is pulled down by the host CPU. If the module is in the idle mode, make sure to pull the RXD to low level by host CPU. SIMCom recommends using GPIO43 or DTR to wake up the module from host CPU and to use GPIO41 or RI to wake up the host CPU. Before designing, pay attention to how to realize waking function and refer to Document[24] and Document[25] for more detail. 5.2.4 Minimum functionality mode Minimum functionality mode ceases a majority function of 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: Disable RF function of the module (Flight mode) If SIM7100A has been set to minimum functionality mode, the module will firstly enter sleep mode, then the RF function and SIM card function will be closed. In this case, the serial port is still accessible, but RF function or SIM card will be unavailable. When SIM7100A is in minimum functionality or flight mode, it can return to full functionality by the AT command “AT+CFUN=1”. 5.3 Current Consumption The current consumption in suspended mode and without USB connection is listed in the table below. Here, “suspended mode” means that SIM7100A is connected to USB bus, but it does not transfer data.

Possible harmful emissions radiate by the application to the RF receiver in the receiver band. RF emissions interfere with audio input/output. It is recommended to shield the sensitive components and trace with common ground and user can add beads where necessary. Normally SIM7100A is mounted on customer host board. Although some ESD components have been added in SIM7100A, to prevent ESD, user should put some ESD components on customers’ board. The ESD components should be placed beside the connectors which human body might touch, such as SIM card holder, audio jacks, switches, keys, etc. The following table is the SIM7100A ESD measurement performance; the results are from SIMCom EVB test.

Safety Caution Table 54: 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 to not operate normally for 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. Forget to think much of these instructions may lead to the flight safety or offend against 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 switched on. RF interference can occur if it is used close to TV sets, radios, 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, for example no mobile fee or a invalid SIM card. While you are in this condition and need emergent help, please remember using 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.
