Power Supply Pin4 VBAT pins are dedicated to connect the supply voltage.Table 7: VBAT Pin descriptionPin typePin nameMinTypMaxUnitPOWERVBAT3.153.84.2V3.1.1 Design GuideMake sure that the input voltage at the VBAT pin will never drop below 3.15V even during a transmitwhen the current consumption up to more than 700mA. If the power voltage drops below 3.15V, themodule may be shut down automatically. Using large tantalum capacitors (above 300uF) will be the bestway 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 thatcapacitors should be put beside VBAT pins as close as possible. Also User should minimize the PCB traceimpedance from the power supply to the VBAT pins through widening the trace to 80 mil or more on theboard. The following figure is the recommended circuit.Figure 6: VBAT input application circuitNote: The Cd, Ce, Cb, Cc and Cf must be mounted for SIM7100C.

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 beused.Figure 7: Reference circuit of the LDO power supplyIf there is a big difference between the input voltage and the desired output (VBAT), a switching converterpower will be preferable because of its better efficiency, especially at the high current situation. Thefollowing figure is the reference circuit. Note that DCDC may deprave RF performance because of ripplecurrent intrinsically.
Smart Machine Smart DecisionSIM7100C_User Manual_V1.01 2015-09-1926Figure 8: Reference circuit of the DCDC power supply3.1.3 Voltage monitorTo monitor the power supply voltage, user can use the AT command “AT+CBC”, this command has twoparameters: the battery status and the voltage value (mV). It will return the capacity percentage and actualvalue of battery (at the VBAT pin). The voltage is continuously measured at intervals, whenever themeasured battery voltage is lower than a specific value set by the AT command “AT+CVALARM”. Forexample, if the voltage value is set to be 3.4V, the following URC will be presented: “warning! voltage islow: 3.3v”.If the voltage is lower than a specific value which is set by the AT command “AT+CPMVT”, the modulewill 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 Sequence3.2.1 Power on SequenceSIM7100C 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.

The PCM interface enablescommunication with an external codec to support hands-free applications. SIM7100C PCM interface canbe 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, SIM7100C can be a master or a slave. In long-sync (auxiliary PCM) mode,SIM7100C is always a master. SIM7100C also supports 3 kinds of coding formats: 8 bits (-law or A-law)
Smart Machine Smart DecisionSIM7100C_User Manual_V1.01 2015-09-1938and 16 bits (linear).Note: PCM interface is multiplexed from GPIO (default setting). The AT command “AT+CPCM” isused to switch between PCM and GPIO functions.

The data changes on the highlevel of PCM_CLK and is sampled at the falling edge of PCM_CLK in one period. Primary PCM isdisabled after every power-on or every reset event. So user must use AT command to enable the primaryPCM mode after powering on or resetting the module every time if user wants to use PrimaryPCM.SIM7100C PCM Interface can be operated in Master or Slave mode if it is configured to primaryPCM. 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 themodule. Both PCM modes are discussed in this section followed by additional PCM topics.3.6.3 Auxiliary PCM (128 KHz PCM clock)-law coding is supported by the auxiliary PCM. The auxiliary codec port operates with standard
Smart Machine Smart DecisionSIM7100C_User Manual_V1.01 2015-09-1939long-sync timing and a 128 KHz clock. The AUX_PCM_SYNC runs at 8 KHz with 50% duty cycle.Most -law codec support the 128 KHz clock.Figure 20: Synchrony timingFigure 21: EXT CODEC to MODULE timingFigure 22: MODULE to EXT CODEC timingTable 20: Timing parametersParameterDescriptionMinTypMaxUnitT(auxsync)AUX_PCM_SYNC cycle time–125-μs

Smart Machine Smart DecisionSIM7100C_User Manual_V1.01 2015-09-19564.2 Antenna Design GuideSIM7100C provides RF antenna interface. Customer’s antenna should be located in the host board andconnected to module’s antenna pad through micro-strip line or other types of RF trace and the traceimpedance must be controlled in 50Ω. SIMCom recommends that the total insertion loss between theantenna pad and antenna should meet the following requirements:●LTE (F<1GHz) <0.5dB●LTE (1GHz<F<2GHz) <0.9dB●LTE (2GHz<F) <1.2dBTo facilitate the antenna tuning and certification test, a RF connector and an antenna matching circuitshould be added. The following figure is the recommended circuit.Figure 32: Antenna matching circuit (MAIN_ANT)In this figure, the components R4,C3,C4 and R4 is used for antenna matching, the value of componentscan only be got after the antenna tuning, usually, they are provided by antenna vendor. By default, the R3,R4 are 0 Ohm resistors, and the C3, C4 are reserved for tuning.The RF test connector in the figure is used for the conducted RF performance test, and should be placed asclose as to the module’s antenna pin. The traces impedance between components must be controlled in50ohm.
Smart Machine Smart DecisionSIM7100C_User Manual_V1.01 2015-09-1957Figure 33: Antenna matching circuit (AUX_ANT)In above figure, R1, C1, C2 and R2 are used for diversity antenna matching. By default, the R1, R2 are 0Ohm resistors, and the C1, C2 are reserved for tuning.4.3 GNSS (GPS and GLONASS)SIM7100C merges GNSS (GPS/GLONASS) satellite and network information to provide ahigh-availability solution that offers industry-leading accuracy and performance. This solution performswell, even in very challenging environmental conditions where conventional GNSS receivers fail, andprovides a platform to enable wireless operators to address both location-based services and emergencymandates.4.3.1 GNSS Technical specificationTracking sensitivity -159 dBm（GPS）-158 dBm（GLONASS）Cold-start sensitivity -148 dBmAccuracy (Open Sky) 2.5m (CEP50)TTFF (Open Sky) Hot start <1s Cold start 35sReceiver Type 16-channel, C/A CodeGPS L1 Frequency (1575.42±1.023MHz),GLONASS: 1597.5~1605.8 MHzUpdate rate Default 1 HzNote: Performance will vary depending on the environment, antenna type and signal conditions and soon.4.3.2 GNSS Operate ModeSIM7100C supports both A-GPS and S-GPS, and then provides three operating modes: mobile-assistedmode, mobile-based mode and standalone mode. A-GPS includes mobile-assisted and mobile-based mode.
Smart Machine Smart DecisionSIM7100C_User Manual_V1.01 2015-09-1958In mobile-assisted mode, when a request for position location is issued, available network information isprovided to the location server (e.g. Cell-ID) and assistance is requested from the location server. Thelocation server sends the assistance information to the handset. The handset/mobile unit measures theGNSS observables and provides the GNSS measurements along with available network data (that isappropriate for the given air interface technology) to the location server. The location server thencalculates 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 theinformation required to assist the handset in measuring the satellite signals, but also the informationrequired to calculate the handset’s position. Therefore, rather than provide the GNSS measurements andavailable network data back to the location server, the mobile calculates the location on the handset andpasses 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 assistedmodes. 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 informationTherefore, while network solutions typically perform poorly in rural areas and areas of poor cellgeometry/density, and while unassisted, GNSS-only solutions typically perform poorly indoors. TheSIM7100C GNSS solution provides optimal time to fix, accuracy, sensitivity, availability, and reducednetwork utilization in both of these environments, depending on the given condition.

Temperatures outside of the range-30℃~ +80℃might slightly deviate from ETSI specifications.5.2 Operating Mode5.2.1 Operating ModeThe table below summarizes the various operating modes of SIM7100Cx.Table 45: Operating mode
Smart Machine Smart DecisionSIM7100C_User Manual_V1.01 2015-09-1960ModeStatusFunctionNormaloperationSleepLTEModule will automatically go into sleep mode if theconditions of sleep mode are enabling and there is no on airand no hardware interrupt (such as USB wake-up operation ordata on serial port).In this case, the current consumption of module will bereduced to the minimal level.In sleep mode, the module can still receive paging messageand SMS.IdleLTESoftware is active. Module is registered to the LTE network,and the module is ready to communicate.StandbyLTEModule is ready for EDGE/HSPA+ /LTE data transfer, but nodata is currently sent or received. In this case, powerconsumption depends on network settings and EDGE/HSPA+/LTE configuration.DatatransferLTEThere is EDGE/HSPA+/LTE data transfer in progress. In thiscase, power consumption is related to network settings (e.g.power control level); uplink/downlink data rates and GPRSconfiguration (e.g. used multi-slot settings).Minimumfunctionality modeAT command “AT+CFUN” can be used to set the module to a minimumfunctionality mode without removing the power supply. In this mode, the RFpart of the module will not work or the USIM card will not be accessible, orboth RF part and USIM card will be closed, and the serial port is stillaccessible. The power consumption in this mode is lower than normal mode.5.2.2 Minimize Power ConsumptionThere are two modes that SIM7100C achieves low power consumption.5.2.3 Sleep modeIf peripheral equipments stops working, and there is no on air or hardware interrupts (such as GPIOinterrupts or data on UART), SIM7100C will enter sleep mode automatically. In this mode, SIM7100C canstill receive paging，voice call or SMS from network. If USB interface of SIM7100C is connected to hostCPU, but host CPU does not support USB suspending, then SIM7100C will not enter sleep mode. AfterUSB is disconnected, SIM7100C will enter sleep mode.Note: When UART interface is connected with host CPU, SIM7100C cannot enter sleep mode untilRXD is pulled down by the host CPU. If the module is in the idle mode, make sure to pull the RXD tolow level by host CPU. SIMCom recommends using GPIO43 or DTR to wake up the module from hostCPU and to use GPIO41 or RI to wake up the host CPU. Before designing, pay attention to how torealize waking function and refer to Document[24] and Document[25] for more detail.
Smart Machine Smart DecisionSIM7100C_User Manual_V1.01 2015-09-19615.2.4 Minimum functionality modeMinimum functionality mode ceases a majority function of module, thus minimizing the powerconsumption. 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 SIM7100C has been set to minimum functionality mode, the module will firstly enter sleep mode, thenthe RF function and SIM card function will be closed. In this case, the serial port is still accessible, but RFfunction or SIM card will be unavailable. When SIM7100C is in minimum functionality or flight mode, itcan return to full functionality by the AT command “AT+CFUN=1”.5.3 Current ConsumptionThe current consumption in suspended mode and without USB connection is listed in the table below.Here, “suspended mode” means that SIM7100C is connected to USB bus, but it does not transfer data.Table 46: Current consumptionOFF stateOFF state supply currentPower down 10uA5.4 EMC and ESD NotesEMC tests should be performed to detect any potential problems. Possible harmful emissions radiate bythe application to the RF receiver in the receiver band. RF emissions interfere with audio input/output. It isrecommended to shield the sensitive components and trace with common ground and user can add beadswhere necessary.Normally SIM7100C is mounted on customer host board. Although some ESD components have beenadded in SIM7100C, to prevent ESD, user should put some ESD components on customers’ board. TheESD components should be placed beside the connectors which human body might touch, such as SIMcard holder, audio jacks, switches, keys, etc. The following table is the SIM7100C ESD measurementperformance; the results are from SIMCom EVB test.Table 47: The ESD performance measurement table (Temperature: 25℃, Humidity: 45%)
