Section 13 Smart Card Interface
13.3.2
Figure 13.2 shows a schematic diagram of smart card interface related pin connections.
In communication with an IC card, since both transmission and reception are carried out on a
single data communication line, the chip’s TxD pin and RxD pin should both be connected to the
line, as shown in the figure. The data communication line should be pulled up to the V
supply with a resistor.
When the clock generated on the smart card interface is used by an IC card, the SCK pin output is
input to the CLK pin of the IC card. No connection is needed if the IC card uses an internal clock.
Chip port output is used as the reset signal.
Other pins must normally be connected to the power supply or ground.
Note: If an IC card is not connected, and the TE and RE bits are both set to 1, closed
