VBAT directly supplies the power to RF circuit and baseband circuit. All four VBAT pins of SIM5360A must be used together. VBAT directly supplies the power to RF PA and baseband system. For the VBAT, the ripple due to GSM/GPRS emission burst (every 4.615ms）may cause voltage drop, and the current consumption rises typically to peak of 2A. So the power supply must be able to provide sufficient current up to more than 2A. The following figure is the VBAT voltage ripple wave at the maximum power transmit phase. The test condition: VBAT =4.0V, VBAT maximum output current =2A, CA=100 µF tantalum capacitor
Smart Machine Smart Decision SIM5360A_User_Manual_V1.03 2014-07-03 22(ESR=0.7Ω) and CB=1µF(Please refer to Figure 8—Application circuit). Figure 7: VBAT voltage drop during burst emission (GSM/GPRS) 3.1.1 Power Supply Pin Two VBAT pins are dedicated to connect the supply voltage. Table 4: Pin description Pin type Pin name Min Typ Max Unit POWER VBAT 3.4 3.8 4.2 V Note: 1. When the module is power off, users must pay attention to the issue about current leakage. Refer to Chapter 3.10.2. 3.1.2 Design Guide Make sure that the input voltage at the VBAT pin will never drop below 3.3V even during a transmit burst when the current consumption rises up to more than 2A. If the power voltage drops below 3.3V, the module may be shut down automatically. Using large tantalum capacitors (above 100uF) will be the best way to reduce the voltage drops. If the power current cannot support up to 2A, users must introduce larger capacitor (typical 1000uF) to storage electric power, especially GPRS multiple time slots emission. 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. 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.

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 4.1V, here a linear regulator can be used. Figure 9: 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
Smart Machine Smart Decision SIM5360A_User_Manual_V1.03 2014-07-03 24power 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. Figure 10: Reference circuit of the DCDC power supply Volta ge monito r 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 is disabled by default, user can enable it by the AT command “AT+CVALARM”. Please refer to Document [1]. 3.1.3 RTC Backup The module uses RTC (Real Time Clock) to update and maintain inherent time and keeps system alive at no power supply status. The RTC power supply of module can be provided by an external capacitor or a battery (non-chargeable or rechargeable) through the VRTC. The following figures show various reference circuits for RTC back up. The discharge current is less than 10uA.  External capacitor backup

When the bus is free, both lines are high. 3.6.3 Design Guide For SIM5360, the data on the I2C bus can be transferred at rates up to 400kbps. The number of peripheral devices connected to the bus is solely dependent on the bus capacitance limit of 400pF. Note that PCB traces length and bending are in users’ control to minimize load capacitance. Note：SDA and SCL have none pulled up resistors in module. So there is need to pull them up in users’ application circuit. 3.7 Keypad Interface SIM5360A module provides a keypad interface that supports five sense lines, or columns, and five keypad rows.

Refer to section 3.11 and document [1] for details. 2. When the module is powered off, make sure all digital interfaces (PCM UART, etc) connected with peripheral devices have no voltage higher than 0.3V. If users’ design cannot meet above conditions, high level voltages maybe occur in GPIO pins because current leakage from above digital interfaces may occur. 3.11 PCM Interface SIM5360A provides hardware PCM interface for external codec. The PCM interface enables communication with an external codec to support hands-free applications. SIM5360A 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, SIM5360A can be a master or a slave. In long-sync (auxiliary PCM) mode, SIM5360A is always a master. SIM5360A 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.

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.SIM5360A 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. Auxiliary PCM (128 KHz PCM clock) -law coding is supported by the auxiliary PCM. The auxiliary codec port operates with standard long-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 28: Synchrony timing

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 SIM5360A GNSS solution provides optimal time to fix, accuracy, sensitivity, availability, and reduced network utilization in both of these environments, depending on the given condition. 3.12.3 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 SIM5360A in proper operating mode by AT command. Please refer to related document for details. SIM5360A can also get position location information through AT directly. Note: 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.

Refer to AGPS application document for details. 3.13 Multi-functional interface SIM5360A merges functions for various applications. It can enrich users’ design and lower the cost of users’ hardware. 3.13.1 Sink Current Source The dedicated pin (ISINK) is intended for driving passive devices，such as LCD backlight, this implementation is VBAT tolerant and suitable for driving white LEDs. The high-current driver can maintain a constant current which is set by the AT command “AT+ CLEDITST”, capable of up to 40 mA. Table 28: Electronic characteristic Symbol Description Min Typ Max Unit ISINK Input voltage 0.5 VDD VBAT V IO Input current 5 - 40 mA Since the driver is ground-referenced current sink, the operating device it drives must form a current path between the VDD pin and the ISINK pin. The following figure is for users reference.

Smart Machine Smart Decision SIM5360A_User_Manual_V1.03 2014-07-03 523.13.2 Reset Function SIM5360A also have a RESET pin (PIN4) to reset the module. This function is used as an emergency reset only when AT command “AT+CPOF” and the POWERKEY pin has no effect. 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. Treset >50msRESET4.7K47KReset LogicMODULEReset ImpulseRESET Figure 38: Reset circuit Note：50ms<Treset<200ms.

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. SIMCom recommends that the total insertion loss between the antenna pad and antenna should meet the following requirements:
