Hardware Description

3.17Smart Card interface, SCI

The ARM926EJ-S PXP Development Chip contains a PrimeCell Smart Card Interface (SCI). A second SCI is implemented in the FPGA.

There are two sets of Smart Card connectors on the board, J25/J48 and J26/J49. Only one header is fitted for each channel. The connector numbers refer to different size connectors that can be can be fitted. (J25 and J26 are large connectors. J48 and J49 are small connectors.)

Figure 3-35 on page 3-82 shows the tristate buffers that are used to provide the interface between the SCI and the cards. The 16-way box header J28 enables you to monitor the signals or to connect an off-board smart card connector.

SCI0 output signals go to both the RealView Logic Tile connectors and the Smart Card connector. The signals from the SC0 connector to the interface can be disabled by a tile pulling nDRVEN1 HIGH. This enables a RealView Logic Tile to implement a device that communicates with the ARM926EJ-S PXP Development Chip using the Smart Card interface protocol.
