Smart Machine Smart DecisionSIM5320ALD_User Manual_V1.01 2014-08-20223Application Interface Specification3.1 Power SupplyThe power supply pins of SIM5320ALD include VBAT_RF and VBAT_BB. VBAT_RF directly suppliesthe power to RF PA; VBAT_BB supplies the power to the baseband system. For the VBAT_RF, the currentconsumption rises typically to peak of more than 2A. So the power supply must be able to providesufficient current up to more than 2A. The following figure is the VBAT_RF voltage ripple wave at themaximum power transmit phase.Please refer to Figure 8—Application circuit VBAT_RF=4.0V, VBAT maximum output current =2A,CA=100 µF tantalum capacitor (ESR=0.7Ω) and CB=1µF.3.1.1 Power Supply PinTwo VBAT_RF and two VBAT_BB pins are dedicated to connect the supply voltage.Table 4: Pin descriptionPin type Pin name Min Typ Max UnitPOWER VBAT_RF 3.3 3.8 4.2 VVBAT_BB 3.3 3.8 4.2 VNote: 1.Though the VBAT_RF and VBAT_BB are supplied by the same voltage level, they are different pins. VBAT_RFis for RF section and VBAT_BB is for baseband system.2. When the module is power off, users must pay attention to the issue about current leakage. Refer to Chapter 3.10.2Note2.3.1.2 Design GuideMostly, user connects the VBAT_RF and VBAT_BB pins with one power supply. Make sure that the inputvoltage at the VBAT_BB pin will never drop below 3.3V even during a transmit burst when the currentconsumption rises up to more than 2A. If the power voltage drops below 3.3V, the module may be shutdown automatically. Using a large tantalum capacitor (above 100uF) will be the best way to reduce thevoltage drops. If the power current cannot support up to 2A, users must introduce larger capacitor (typical1000uF) to storage electric power.For the consideration of RF performance and system stability, another large capacitor (above 100uF)should be located at the VBAT_RF pin and some multi-layer ceramic chip (MLCC) capacitors (0.1uF)need to be used for EMC because of their low ESR in high frequencies. Note that capacitors should be put
Smart Machine Smart DecisionSIM5320ALD_User Manual_V1.01 2014-08-2023beside VBAT_RF pins as close as possible. Also User should minimize the PCB trace impedance from thepower supply to the VBAT pins through widening the trace to 80 mil or more on the board. The followingfigure is the recommended circuit.Figure 8: VBAT input application circuitThere are three sections about how to design and optimize users’ power systems.Power supply circuitWe recommend DCDC or LDO is used for the power supply of the module, make sure that the peakcurrent 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 4.1V, here a linear regulator can beused.Figure 9: 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 DecisionSIM5320ALD_User Manual_V1.01 2014-08-2024Figure 10: Reference circuit of the DCDC power supplyVoltage 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_BB 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 is disabled by default, user can enable it by the AT command “AT+CVALARM”.Auto power off feature is disabled by default, user should set it by the AT command “AT+CPMVT” to an appropriatevalue.

Smart Machine Smart DecisionSIM5320ALD_User Manual_V1.01 2014-08-20313.3.2 Application GuideIf UART port is used in Null Modem, the pin “RI” can be used as an interrupt signal to HOST. Normally itwill keep high logic level until certain condition such as receiving SMS, voice call (CSD, video) or URCreporting, then “RI” will change to low logic level to inform the master (client PC). It will stay low untilthe master clears the interrupt event with AT command.Figure 19: RI behaviour in NULL ModemIf Full Modem is used to establish communication between devices, the pin “RI” is another operationstatus. Initially it keeps high, when a voice call or CSD call comes, the pin “RI” will change to low forabout 5900ms, then it will return to high level for 100ms. It will repeat this procedure until this call isanswered or hung up.Figure 20: RI behaviour in FULL ModemTo comply with RS-232 protocol, the RS-232 level shifter chip should be used to connect SIM5320ALDto the RS-232-C interface. In this connection, the TTL level and RS-232 level are converted mutually.SIMCom recommends that user uses the SP3238ECA chip with a full modem.

Smart Machine Smart DecisionSIM5320ALD_User Manual_V1.01 2014-08-20515.2.1 Operating Modes OverviewTable 41: Operating Modes OverviewMode FunctionSleep mode WCDMASLEEPModule will automatically enter SLEEP mode if DTR is set to highlevel and there is no on air or hardware interrupt (such as GPIOinterrupt or data on serial port).In this case, the current consumption of module will be reduced to theminimal level.In SLEEP mode, the module can still receive paging message，voicecall and SMS.WCDMAWCDMAIDLEModule has registered to the WCDMA network, and the module isready to communicate.WCDMATALKModule is active in WCDMA mode. The power consumption dependson network settings.HSDPAHSDPA IDLEModule is ready for data transmission, but no data is currently sent orreceived. Power consumption depends on network settings andHSDPA configurationHSDPADATAThere is HSDPA data transfer (PPP or TCP or UDP) in progress. Inthis case, power consumption is related with network settings (e.g.power control level), uplink/downlink data rates and HSDPAconfigurationPower downModule can be powered down by the AT command “AT+CPOF” or the POWER_ONpin. The power management unit shuts down the power supply of the module, only thepower supply of RTC is remained. The serial interface is not accessible. Operatingvoltage (connected to VBAT) remains applied.MinimumfunctionalitymodeThe AT command “AT+CFUN” can be used to set the module to a minimumfunctionality mode without removing the power supply. In this mode, the RF part ofthe module will not work or the SIM card will not be accessible, or both will be closed,and the serial port is still accessible. The power consumption in this mode is very low.5.2.2 Minimize Power ConsumptionThere are two modes that SIM5320ALD achieves low power consumption.Sleep modeIf peripheral equipments stops working, and there is no on air or hardware interrupts (such as GPIOinterrupts or data on UART), SIM5320ALD will enter sleep mode automatically. In this mode,SIM5320ALD can still receive paging ，voice call or SMS from network. If USB interface ofSIM5320ALD is connected to host CPU, but host CPU does not support USB suspending, thenSIM5320ALD will not enter sleep mode. After USB is disconnected, SIM5320ALD will enter sleep mode.Note: When UART interface is connected with host CPU, SIM5320ALD can not enter sleep mode until RXD is pulleddown by the host CPU. If the module is in the idle mode, make sure to pull the RXD to low level by host CPU. SIMComrecommends using GPIO43 or UART_DTR to wake up the module from host CPU and to use GPIO41 or UART_RI to
Smart Machine Smart DecisionSIM5320ALD_User Manual_V1.01 2014-08-2052wake up the host CPU. Before designing, pay attention to how to realize waking function and refer to Document[24] andDocument[25] for more detail.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 SIM5320ALD 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 SIM5320ALD is in minimum functionality orflight mode, it can return to full functionality by the AT command “AT+CFUN=1”.Note: For flight mode, please refer to Chapter3.9.2.5.3 Current ConsumptionThe current consumption in suspended mode and without USB connection is listed in the table below.Here, “suspended mode” means that SIM5320ALD is connected to USB bus, but it does not transfer data.Table 42: Current consumptionUMTS Sleep Mode (without USB connection)WCDMA 1900Sleep @DRX=9 2.2mASleep @DRX=8 2.7 mASleep @DRX=6 4.7mAWCDMA 850Sleep @DRX=9 2.2mASleep @DRX=8 2.7 mASleep @DRX=6 4.7mAUMTS Sleep Mode (with USB suspended)WCDMA 1900Sleep @DRX=9 2.4mASleep @DRX=8 2.8 mASleep @DRX=6 4.8mAWCDMA 850Sleep @DRX=9 2.4mASleep @DRX=8 2.8 mASleep @DRX=6 4.8mAHSDPA DataWCDMA 1900 @Power 23dBm CQI=22 Typical 610mA@Power 21dBm CQI=5 Typical 540mA

Possible harmful emissions radiate bythe application to the RF receiver in the receiver band. It is recommended to shield the sensitivecomponents and trace with common ground and user can add beads where necessary.Normally SIM5320ALD is mounted on customer host board. Although some ESD components have beenadded in SIM5320ALD, 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, switches, keys, etc. The following table is the SIM5320ALD ESD measurement performance;the results are from SIMCom EVB test.Table 43: The ESD performance measurement table (Temperature: 25℃, Humidity: 45%)Part Contact discharge Air dischargeVBAT,GND ±4KV ±6KVUART,USB ±2KV ±6KVAntenna port ±4KV ±6KVOther ports ±2KV ±2KV
