Smart Machine Smart DecisionSIM7000 _Hardware Design _V1.00 2017-05-233Interface Application3.1 Power SupplyPin 55, pin 56 and pin 57 are VBAT power input.On VBAT pads, the ripple current up to 0.6A typically due to LTE CAT-M1emission burst and upto 2A typically due to GSM/GPRS emission burst (every 4.615ms). It may cause voltage drop. Sothe power supply for these pads must be able to provide sufficient current up to more than 2A inorder to avoid the voltage drop is more than 300mV.The following figure shows the VBAT voltage ripple wave at the maximum power transmit phasein GSM emission mode.Figure 5: VBAT voltage drop during burst emission (GSM/GPRS)Note: The test condition: The voltage of power supply for VBAT is 3.8V, Cd=100 µF tantalumcapacitor (ESR=0.7Ω) and Cf =100nF (Please refer to Figure 6—Application circuit).Table 6: VBAT pins electronic characteristicSymbolDescriptionMin.Typ.Max.UnitVBATModule power voltage3.03.84.3VIVBAT(peak)Module power peak current in GSM emission mode.-2-AModule power peak current in LTE CAT-M1emissionmode.-0.6-AIVBAT(average)Module power average current in normal modePlease refer to the table 32IVBAT(sleep)Power supply current in sleep modeIVBAT(power-off)Module power current in power off mode.--7uA
Smart Machine Smart DecisionSIM7000 _Hardware Design _V1.00 2017-05-233.1.1 Power Supply Design GuideMake sure that the voltage on the VBAT pins will never drop below 3.0V, even during a transmitburst, when current consumption may rise up to 2A. If the voltage drops below 3.0V, module willbe work abnormally.Note: If the power supply for VBAT pins can support up to 2A, using a total of more than 300uFcapacitors is recommended, or else users must using a total of 1000uF capacitors typically, inorder to avoid the voltage drop is more than 300mV.Some multi-layer ceramic chip (MLCC) capacitors (0.1uF, 1uF) with low ESR in high frequencyband can be used for EMC.These capacitors should be put as close as possible to VBAT pads. Also, users should keep VBATtrace on circuit board wider than 2 mm to minimize PCB trace impedance. The following figureshows the recommended circuit.Figure 6: Power supply application circuitIn addition, for over voltage protection, it is suggested to use a zener diode with 5.1V reversevoltage and more than 500mW power dissipation.Table 7: Recommended Zener diode listNo.ManufacturerPart NumberPower dissipationPackage1On semiMMSZ5231BT1G500mWSOD1232PrisemiPZ3D4V2H500mWSOD3233VishayMMSZ4689-V500mWSOD1234CrownpoCDZ55C5V1SM500mW08053.1.2 Recommended Power Supply CircuitIt is recommended that a switching mode power supply or a linear regulator power supply is used.It is important to make sure that all the components used in the power supply circuit can resist apeak current up to 2A.
Smart Machine Smart DecisionSIM7000 _Hardware Design _V1.00 2017-05-23The following figure shows the linear regulator reference circuit with 5V input and 3.8V output.Figure 7: Linear regulator reference circuitIf there is a big voltage difference between input and output for VBAT power supply, or theefficiency is extremely important, then a switching mode power supply will be preferable. Thefollowing figure shows the switching mode power supply reference circuit.Figure 8: Switching mode power supply reference circuitNote: The Switching Mode power supply solution for VBAT must be chosen carefully againstElectro Magnetic Interference and ripple current from depraving RF performance.3.1.3 Voltage MonitorTo monitor the VBAT voltage, the AT command “AT+CBC” can be used.To monitor whether the VBAT voltage is inside a special range, the AT command“AT+CBATCHK” can be used to enable the overvoltage warning function and the under-voltagewarning function. The default value of the overvoltage warning function in the software is 4.3V,and the default value of the under-voltage warning function is 3.1V.When the VBAT voltage is out of the range, the module will be power off. If users need to poweroff SIM7000 when the VBAT voltage is out of the range, the AT command “AT+CBATCHK” canbe used to enable the overvoltage power-off function and the under-voltage power-off function. Thedefault value of the overvoltage power-off function in the software is 4.4V, and the default value ofthe under-voltage power-off function is 2.9V.Note: Under-voltage warning function and under-voltage power-off function are disabled bydefault. For more information about these AT commands, please refer to Document [1].
Smart Machine Smart DecisionSIM7000 _Hardware Design _V1.00 2017-05-233.2 Power on/Power off/Reset Function3.2.1 Power onSIM7000 can be powered on by pulling the PWRKEY pin to ground.The PWRKEY pin has been pulled up with a diode to 1.8V internally, so it does not need to bepulled up externally. It is strongly recommended to put a 100nF capacitor and an ESD protectiondiode close to the PWRKEY pin, as it would strongly enhance the ESD performance of PWRKEYpin. Please refer to the following figure for the recommended reference circuit.Figure 9: Reference power on/off circuitThe power-on scenarios are illustrated in the following figure.Figure 10: Power on timing sequence

The voltage range can be set byAT command “AT+CBATCHK”.●Method 4: over-temperature or under-temperature automatic power off.Note: If the temperature is outside the range of -30~+80℃, some warning will be reported viaAT port. If the temperature is outside the range of -40~+85℃, SIM7000 will be powered offautomatically.For details about “AT+CPOWD” and “AT+CBATCHK”, please refer to Document [1].These procedures will make modules disconnect from the network and allow the software to enter asafe state, and save data before module be powered off completely.The power off scenario by pulling down the PWRKEY pin is illustrated in the following figure.Figure 11: Power off timing sequence

Whenmodule has been powered on and firmware goes ready, STATUS will be high level, or elseSTATUS will still low level.3.2.3 Reset FunctionSIM7000 can be reset by pulling the RESET pin to ground.Note: This function is only used as an emergency reset. The RESET pin will be ineffectivenessin the power off mode.The RESET pin has been pulled up to 1.8V with a 40KΩ resistor internally. So it does not need tobe pulled up externally. It is strongly recommended to put a100nF capacitor and an ESD protectiondiode close to the RESET pin. Please refer to the following figure for the recommended referencecircuit.Figure 12: Reference reset circuit

AT commands and data transmission can be performed throughUART interface.Moreover, if users need to use two UART simultaneously, SIM7000 also provides a 2-wire UARTinterface multiplex from GPIO. The GPIO0 multiplex as TXD of the 2-wire UART, and the GPIO1multiplex as RXD of the 2-wire UART. Standard version cannot support this function3.3.1 UART Design GuideThe following figures show the reference design.Figure 13: UART full modemFigure 14: UART null modem
Smart Machine Smart DecisionSIM7000 _Hardware Design _V1.00 2017-05-23The SIM7000 UART is 1.8V voltage interface. If user’s UART application circuit is 3.3V voltageinterface, the level shifter circuits should be used for voltage matching. The TXB0108RGYRprovided by Texas Instruments is recommended. The following figure shows the voltage matchingreference design.Figure 15: Reference circuit of level shiftTo comply with RS-232-C protocol, the RS-232-C level shifter chip should be used to connectSIM7000 to the RS-232-C interface, for example SP3238ECA, etc.Note: SIM7000 supports the following baud rates: 300, 600, 1200, 2400, 4800, 9600, 19200,38400, 57600, 115200, 230400, 460800, 921600, 3200000, 3686400, 4000000bps. The defaultband rate is 115200bps.3.3.2 RI and DTR BehaviorThe RI pin description:The RI pin can be used to interrupt output signal to inform the host controller such as applicationCPU.Normally RI will keep high level until certain conditions such as receiving SMS, or a URC reportcoming, and then it will change to low level. It will stay low until the host controller clears theinterrupted event with “AT+CRIRS” AT command.Figure 16: RI behaviour（SMS and URC report）
Smart Machine Smart DecisionSIM7000 _Hardware Design _V1.00 2017-05-23Normally RI will be kept at a high level until a voice call, then it will output periodic rectangularwave with 5900ms low level and 100ms high level. It will output this kind of periodic rectangularwave until the call is answered or hung up.Figure 17: RI behaviour（voice call）Note: For more details of AT commands about UART, please refer to document [1] and [22].The DTR pin description:After setting the AT command “AT+CSCLK=1”, SIM7000 will enter sleep mode by pulling up theDTR pin when module is in the idle mode. In sleep mode, the UART is unavailable. WhenSIM7000 enters sleep mode, pulling down DTR can wake up module.3.4 USB InterfaceThe SIM7000 contains a USB interface compliant with the USB2.0 specification as a peripheral,but the USB charging function is not supported.SIM7000 supports the USB suspend and resume mechanism which can reduce power consumption.If there is no data transmission on the USB bus, SIM7000 will enter suspend mode automatically,and will be resumed by some events such as voice call, receiving SMS, etc.Figure 18: USB reference circuitBecause of the high speed on USB bus, more attention should be paid to the influence of thejunction capacitance of the ESD component on USB data lines. Typically, the capacitance of the D1and D2 should be less than 1pF.D3 is suggested to select the diode with anti-ESD and voltage surge function, or customer couldadd a ZENER diode for surge clamping.Note：The USB_DM and USB_DP nets must be traced by 90Ohm+/-10% differential impedance.

Note that the SIMperipheral circuit should be close to the SIM card socket. The following figure shows the 6-pinSIM card holder reference circuit.Figure 19: SIM interface reference circuit
Smart Machine Smart DecisionSIM7000 _Hardware Design _V1.00 2017-05-23Note: SIM_DATA has been pulled up with a 10KΩ resistor to SIM_VDD in module. A 100nFcapacitor on SIM_VDD is used to reduce interference. For more details of AT commands aboutSIM, please refer to document [1].SIM_CLK is very important signal, the rise time and fall timeof SIM_CLK should be less than 40ns, otherwise the SIM card might not be initialized correctly.If SIM_DET is used, a 10KΩ resistor is necessary to pulling up to the power VDD_EXT.3.5.2 Recommended SIM Card HolderIt is recommended to use the 6-pin SIM socket such as C707 10M006 512 produced by Amphenol.User can visit http://www.amphenol.com for more information about the holder.Figure 20: Amphenol SIM card socketTable 13: Amphenol SIM socket pin descriptionPinSignalDescriptionC1SIM_VDDSIM Card Power supply.C2SIM_RSTSIM Card Reset.C3SIM_CLKSIM Card Clock.C5GNDConnect to GND.C6VPPC7SIM_DATASIM Card data I/O.

Smart Machine Smart DecisionSIM7000 _Hardware Design _V1.00 2017-05-234.2 LTE CAT-M1 Antenna Design GuideUsers should connect antennas to SIM7000’s antenna pads through micro-strip line or other typesof RF trace and the trace impedance must be controlled in 50Ω. SIMCom recommends that thetotal insertion loss between the antenna pads and antennas should meet the following requirements:Table 24: Trace lossFrequencyLoss700MHz-960MHz<0.5dB1710MHz-2170MHz<0.9dB2300MHz-2650MHz<1.2dBTo facilitate the antenna tuning and certification test, a RF connector and an antenna matchingcircuit should be added. The following figure is the recommended circuit.
Smart Machine Smart DecisionSIM7000 _Hardware Design _V1.00 2017-05-23Figure 28: Antenna matching circuit (MAIN_ANT)In figure 28, the components L101,C106,C107 and R101 or R102 are used for antenna matching,
Smart Machine Smart DecisionSIM7000 _Hardware Design _V1.00 2017-05-23the values of components can only be achieved after the antenna tuning and usually provided byantenna vendor. By default, the L101,R101or R102 are 0 Ωresistors, and the C106, C107 arereserved for tuning. The RF test connector is used for the conducted RF performance test, andshould be placed as close as to the module’s MAIN_ANT pin. The traces impedance betweenSIM7000 and antenna must be controlled in 50Ω.4.3 GNSSSIM7000 merges GNSS (GPS/GLONASS/BD) satellite and network information to provide ahigh-availability solution that offers industry-leading accuracy and performance. This solutionperforms well, even in very challenging environmental conditions where conventional GNSSreceivers fail, and provides a platform to enable wireless operators to address both location-basedservices and emergency mandates.4.3.1 GNSS Technical specificationTracking sensitivity: -162 dBm（GPS）/-158 dBm（GLONASS）/TBD (BD)Cold-start sensitivity: -148 dBmAccuracy (Open Sky): 2.5m (CEP50)TTFF (Open Sky) : Hot start <1s, Cold start<35sReceiver Type: 16-channel, C/A CodeGPS L1 Frequency: 1575.42±1.023MHzGLONASS: 1597.5~1605.8 MHzBD: 1559.05~1563.14 MHzUpdate rate: Default 1 HzGNSS data format: NMEA-0183GNSS Current consumption : 100mA (GSM/LTE CAT-M1Sleep ,in total on VBAT pins)GNSS antenna: Passive/Active antennaNote: If the antenna is active type, the power should be given by main board because there is nopower supply on the GPS antenna pad. If the antenna is passive, it is suggested that the externalLNA should be used.4.3.2 GNSS Application GuideUsers can adopt an active antenna or a passive antenna to SIM7000. If using a passive antenna, anexternal LNA is a must to get better performance. The following figures are the reference circuits.
Smart Machine Smart DecisionSIM7000 _Hardware Design _V1.00 2017-05-23Figure 29: Active antenna circuitFigure 30: Passive antenna circuit (Default)In above figures, the components C1, L1 and L2 are used for antenna matching. Usually, the valuesof the components can only be achieved after antenna tuning and usually provided by antennavendor. C2 is used for DC blocking. L3 is the matching component of the external LNA, and thevalue of L3 is determined by the LNA characteristic and PCB layout. Both VDD of active antennaand V_LNA need external power supplies which should be considered according to active antennaand LNA characteristic. LDO/DCDC is recommended to get lower current consuming by shuttingdown active antennas and LNA when GNSS is not working.GNSS can be tested by NMEA port. NMEA sentences can be obtained through UART or USBautomatically. NMEA sentences include GSV, GGA, RMC, GSA, and VTG. Before using GNSS,user should configure SIM7000 in proper operating mode by AT command. Please refer to relateddocuments for details. SIM7000 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 hastwo parameters, the first is on/off, and the second is GNSS mode. Default mode is standalonemode.AGPS mode needs more support from the mobile telecommunication network. Please refer todocument [24] 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.

Safety CautionTable 40: Safety CautionMarksRequirementsWhen in a hospital or other health care facility, observe the restrictions about the useof mobiles. Switch the cellular terminal or mobile off, medical equipment may besensitive and not operate normally due to RF energy interference.Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it isswitched off. The operation of wireless appliances in an aircraft is forbidden toprevent interference with communication systems. Forgetting to think much of theseinstructions 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 orfumes. Switch off the cellular terminal when you are near petrol stations, fuel depots,chemical plants or where blasting operations are in progress. Operation of anyelectrical equipment in potentially explosive atmospheres can constitute a safetyhazard.Your cellular terminal or mobile receives and transmits radio frequency energy whileswitched 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 whendriving 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 cellularnetworks and cannot be guaranteed to connect in all conditions, especially with amobile fee or an invalid SIM card. While you are in this condition and need emergenthelp, please remember to use emergency calls. In order to make or receive calls, thecellular terminal or mobile must be switched on and in a service area with adequatecellular signal strength.Some networks do not allow for emergency call if certain network services or phonefeatures are in use (e.g. lock functions, fixed dialing etc.). You may have todeactivate those features before you can make an emergency call.Also, some networks require that a valid SIM card be properly inserted in the cellularterminal or mobile.
