TDA8024 Datasheet (NXP) - Standard smart card interface

TDA8024, Standard smart card interface

The TDA8024 is a complete and cost-efficient analog interface for asynchronous 3 V or 5 V smart cards.

It can be placed between the card and the microcontroller to perform all supply, protection and control functions.

Very few external components are required.

The TDA8024AT is a direct replacement

TDA8024 Features

* IC card interface

* 3 V or 5 V supply for the IC (VDD and GND)

* Three specifically protected half-duplex bidirectional buffered I/O lines to card contacts C4, C7 and C8

* DC-to-DC converter for VCC generation separately powered from a 5 V  20% supply (VDDP and PGND)

* 3 V or
