TDA8000 - Smart card interface

General Description

The TDA8000 is a complete, low-cost analog interface which can be positioned between a smart card or a memory card (ISO 7816) and a microcontroller.

It is approved for banking, telecom and pay TV applications.

Key Features

  • Two protected I/O lines.
  • VCC regulation (5 V ±4%, 100 mA max. with controlled rise and fall times).
  • VPP generation (12.5, 15 or 21 V ±2.5%, 50 mA max. programmable by two bits, with controlled rise and fall times).
  • Clock generation (up to 8 MHz).
  • Short-circuit, thermal and card extraction protections.
  • Two voltage supervisors (digital and analog supplies).
  • Automatic activation and deactivation sequences via an independent internal cl.
