Introduction

This document describes the AT89EVK-01 evaluation kit dedicated to the AT83C24
Smart Card Reader Interface IC. This board is designed to allow an easy evaluation of
the AT83C24 on an application using the TDA8004.

This board can be connected on the TDA8004 footprint.

1.1

Features

The AT89EVK-01 provides the following features:

Possibility to replace the TDA8004 (or TDA8024) with the AT89EVK-01 board . The 
AT89EVK-01 board is soldered on the TDA8004 footprint.

The AT83C24 registers are programmed with the TWI link (SDA,SCL). The 
T89C5121 microcontroller sends the TWI commands to configure the AT83C24 
registers.

The configuration software is stored in T89C5121 Flash memory. The program can be 
reloaded by using FLIP / BatchISP (In-System Programming tool) and an RS-232 
adaptor board (CEIBO for example).

Hardware configuration allowed with switches and solder pads.

The program can be modified and reloaded with Batchisp (see 2.2.2)
