Pin Signal Description
C1
USIM_VDD
SIM Card Power supply, it can identify automatically the SIM
Card power mode，one is 3.0V±10%, another is 1.8V±10%.
Current is about 10mA.
C2
USIM_RST SIM Card Reset.
C3
USIM_CLK SIM Card Clock.
C5
GND Connect to GND.
C6
VPP Connect to USIM_VDD
C7
USIM_DATA SIM Card data I/O.
3.10 I2C interface
SIM5216A contains an I2C interface.It is used for connecting peripheral equipment. Use AT
Command to read/write values of I2C peripheral equipment.
AT+CRIIC is used for read
values from register of I2C peripheral equipment. AT+CWIIC is used for write values to register
of I2C peripheral equipment
Because I2C has been pulled up in SIM5216A, there is no need
to be pulled up by customer.
Table 18: PIN define of IIC interface
*Note
： IIC_SDA and IIC_SCL have been pulled up with two 2.2kR resistors to 2.6V in module.
So there is no need to pull them up in your application circuit.
Pin Name Function Lever
47 IIC_SDA Serial interface data input and output
46 IIC_SCL Serial interface clock input
