External SIM Interface
4 signals exist:
• SIMVCC: SIM power supply.
• SIMRST: reset.
• SIMCLK: clock.
• SIMDATA : I/O port.
The SIM interface controls a 3V SIM. This interface is fully compliant with GSM 11.11
recommendations concerning SIM functions.
It is recommended to add Transient Voltage Suppressor diodes on the signal connected to the
SIM socket in order to prevent any Electrostatic Discharge. TVS diodes with low capacitance
(less than 10pF) have to be connected on SIMCLK and SIMDATA to avoid any disturbance of the
rising and falling edge. These types of diodes are mandatory for the Full Type Approval. They
shall be placed as close as possible to the SIM socket.
