TDA8004T Overview
The TDA8004T is a plete low cost analog interface for asynchronous smart cards. It can be placed betw the card and the microcontroller with very few external ponents to perform all supply protection and control functions. ORDERING INFORMATION TYPE NUMBER TDA8004T PACKAGE NAME SO28 DESCRIPTION plastic small outline package;.
TDA8004T Key Features
- 3 or 5 V supply for the IC (GND and VDD)
- Step-up converter for VCC generation (separately powered with a 5 V ±10% supply, VDDP and PGND)
- 3 specific protected half duplex bidirectional buffered I/O lines (C4, C7 and C8)
- Thermal and short-circuit protections on all card contacts
- Automatic activation and deactivation sequences (initiated by software or by hardware in the event of a short-circuit, c
- Enhanced ESD protection on card side (>6 kV)
- 26 MHz integrated crystal oscillator
- Clock generation for the card up to 20 MHz (divided by 1, 2, 4 or 8 through CLKDIV1 and CLKDIV2 signals)
- Non-inverted control of RST via pin RSTIN
- ISO 7816, GSM11.11 and EMV (payment systems) patibility
