ST8024 Datasheet (STMicroelectronics)

ST8024, SMARTCARD INTERFACE

The ST8024 is a complete low cost analog interface for asynchronous 3 V and 5 V smart cards.

It can be placed between the card and the microcontroller with few external components to perform all supply protection and control functions.

ST8024 is a direct replacement of ST8004.

Main applications are:

ST8024 Features

* Designed to be compatible with the NDS conditional access system

* IC card interface

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

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

* DC-DC converter for VCC generation sepa
