IC card interface

GENERAL DESCRIPTION\nThe TDA8004T is a complete low cost analog interface for asynchronous smart cards. It can be placed betw the card and the microcontroller with very few external components to perform all supply protection and control functions.FEATURES\n• 3 or 5 V supply for the IC (GND and VDD) • 3 or 5 V supply for the IC (GND and VDD)\n• Step-up converter for VCCgeneration (separately powered with a 5 V±10% supply, VDDPand PGND)\n• 3 specific protected half duplex bidirectional buffered I/O lines (C4, C7 and C8)\n• VCCregulation 5 V±5% on 2×100 nF or 1×100 nF and 1×220 nF multila;
