Section 30 SIM Card Module (SIM)

(5) Pin Connections

An example of pin connections for the smart card interface is shown in figure 30.11.

In communication with the smart card, transmission and reception are performed using a single

data transmit line. The data transmit line should be pulled up by a resistance on the power supply

Vcc side.

When using the clock generated by the smart card interface with the IC card, the SIM_CLK pin

output is input to the CLK pin of the IC card. If an internal clock of the IC card is used, this

connection is not needed.

Note: The transmission/reception in loop can perform self-check when the RE and TE bits are

set to 1 without connecting to the IC card.
