8.8.1. Overview

The Smart Card Reader (SCR) is a communication controller that transmits data between the system and Smart Card.

The controller can perform a complete smart card session, including card activation, card deactivation. Cold/warm reset,

Answer to Reset (ATR) response reception, data transfers, etc.

The SCR includes the following features:

 Supports APB slave interface for easy integration with AMBA-based host systems

 Supports the ISO/IEC 7816-3:1997(E) and EMV2000 (4.0) Specifications

 Performs functions needed for complete smart card sessions, including:

- Card activation and deactivation

- Cold/warm reset

- Answer to Reset (ATR) response reception

- Data transfers to and from the card

 Supports adjustable clock rate and bit rate

 Configurable automatic byte repetition

 Support commonly used communication protocols:

- T=0 for asynchronous half-duplex character transmission

- T=1 for asynchronous half-duplex block transmission

 Support FIFOs for receive and transmit buffers (up to 128 characters) with threshold

 Support configurable timing functions:

- Smart card activation time

- Smart card reset time

- Guard time

- Timeout timers

 Supports synchronous and any other non-ISO 7816 and non-EMV cards
