ST8004 Datasheet Smartcard Interface

Manufacturer: STMicroelectronics

Overview: ST8004 Smartcard interface General.

General Description

The ST8004 is a plete low cost analog interface for asynchronous 3V and 5V smart cards.

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

Main applications are: smartcard readers for Set Top Box, IC card readers for banking, identification.

Key Features

  • 3V or 5V supply for the IC.
  • Step-up converter for VCC generation.
  • 3 specific protected half duplex bi-directional buffered I/O lines.
  • Automatic activation and deactivation sequences.
  • Thermal and short-circuit protections on all card contacts.
  • 26MHz integrated crystal oscillator.
  • Clock generation for the card up to 20MHz with synchronous frequency changes.
  • ISO7816-3 compatible.
  • Enhanced ESD protection on card side.
  • SO-28 package.
  • Under volta.
