TDA8005 - Low-power smart card coupler

Description

The TDA8005 is a low cost card interface for portable smart card readers.

Controlled through a standard serial interface, it takes care of all ISO 7816 and GSM11-11 requirements.

Features

  • VCC generation (5 V ±5%, 20 mA maximum with controlled rise and fall times).
  • Clock generation (up to 8 MHz), with two times synchronous frequency doubling.
  • Clock STOP HIGH, clock STOP LOW or 1.25 MHz (from internal oscillator) for cards power-down mode.
  • Specific UART on I/O for automatic direct/inverse convention settings and error management at character level.
  • Automatic activation and deactivation sequences through an independent sequencer.
