It is recommended to use an ESD protection component such as ON SEMI (www.onsemi.com )
ESD9M5.0ST5G (load C 2.5pF) or ESD9L5.0ST5G (load c 0.5pF).
Note: The SIM5300E has two kinds of interface (UART and USB) to connect to host CPU. USB
interface is mapped to six virtual ports: “SimTech HS-USB AT Port 0020”, “SimTech HS-USB
Diagnostics 0020”, “SimTech HS-USB Diagnostics 0020”, “SimTech HS-USB OCT 0020” , “I SimTech
HS-USB Port 0020”, “SimTech HS-USB Port 0020”.
4.10 SPI INTERFACE
SIM5300E provides SPI interface in the embedded AT application. For details about embedded AT
application, please refer to document [1].
Note: This function is not supported in the standard software. If user wants this function, please
contact SIMCom for more details.
4.11 ADC
SIM5300E provides an ADC, which can be used to measure the voltage. User can use AT command
“AT+CADC” to read the voltage value. For details of this AT command, please refer to document [1].
