Standard smart card interface

The TDA8024 is a complete and cost-efficient analog interface for asynchronous 3 V or 5 V smart cards. It can be placed between the card and the microcontroller to perform all supply, protection and control functions. Very few external components are required. The TDA8024AT is a direct replacement f IC card interface\n3 or 5 V supply for the IC (VDD and GND)\nThree specifically protected half-duplex bidirectional buffered I/O lines to card contacts C4, C7 and C8\nDC/DC converter for VCC generation separately powered from a 5 V +- 20 pct supply (VDDP and PGND)\n3 or 5 V +- 5 pct regulated card s;
