TDA8023 - Low power IC card interface

Description

The TDA8023 is a complete cost-efficient, low-power analog interface for synchronous or asynchronous smart cards.

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

2.

Features

  • I2C-bus controlled IC card interface in TSSOP28.
  • Supply voltage from 2.7 V to 6.5 V.
  • Independant supply voltage VDD(INTF) for interface signals with the microcontroller.
  • Shutdown input for very low power consumption when the part is not used.
  • Power reduction modes when the card is active.
  • DC-to-DC converter for VCC generation (capacitive doubler, tripler, or inductive, or follower automatically selected according to supply voltage and card voltage).
  • 1 specific.
