Smart Machine Smart Decision 3 Interface Application 3.1 Power Supply On VBAT pads, a ripple current up to 2A typically, may cause voltage drop. Therefore, the power supply for these pads must be able to provide sufficient current up to more than 2A in order to avoid the voltage drop of more than 300mV. Table 6: VBAT Pins electronic characteristic Symbol Description VBAT Module power voltage 3.4 3.8 IVBAT(peak) Module power peak current in normal mode. 1.
Smart Machine Smart Decision In addition, in order to guard over voltage protection, it is suggested to use a zener diode with 5.1V reverse zener voltage and more than 500mW power dissipation. Table 7: Recommended zener diode list No. Manufacturer Part Number power dissipation 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.
Smart Machine Smart Decision 3.1.3 Voltage Monitor To monitor the VBAT voltage, the AT command “AT+CBC” can be used. For monitoring the VBAT voltage outside or within a special range, the AT command “AT+CVALARM” can be used to enable the under-voltage warning function. If users need to power off Module, when the VBAT voltage is out of a range, the AT command “AT+CPMVT” can be used to enable under-voltage power-off function.

Smart Machine Smart Decision For details about “AT+CPOF” and “AT+CPMVT”, please refer to Document [1]. These procedures will make modules disconnect from the network and allow the software to enter a safe state and save data before modules are powered off completely. The power off scenario by pulling down the PWRKEY pin is illustrated in the following figure.
Smart Machine Smart Decision The RESET pin has been pulled up to 1.8V internally, so it does not need to be pulled up externally. It is strongly recommended to put a100nF capacitor and an ESD protection diode close to the RESET pin. Please refer to the following figure for the recommended reference circuit. Figure 11: Reference reset circuit Table 10: RESET pin electronic characteristic Symbol Description Min.
Smart Machine Smart Decision Figure 12: UART full modem Figure 13: UART null Modem The Module UART is 1.8V voltage interface. If user’s UART application circuit is a 3.3V voltage interface, the level shifter circuits should be used for voltage matching. The TXB0108RGYR provided by Texas Instruments is recommended. The following figure shows the voltage matching reference design.
Smart Machine Smart Decision 3.3.2 RI and DTR Behavior The RI pin can be used to interrupt output signal to inform the host controller such as application CPU. Normally RI will stay at high level until certain conditions such as receiving SMS, or a URC report come in. It will then change to low level. It will stay low until the host controller clears the interrupted event with “AT+CRIRS” AT command.
Smart Machine Smart Decision 3.4.1 USB Application Guide Module can be used as a USB device. Module supports the USB suspend and resume mechanism which can reduce power consumption. If there is no data transmission on the USB bus, Module will enter suspend mode automatically and will be resumed by some events such as voice call, receiving SMS, etc.
