TDA8004T Datasheet | NXP Semiconductors

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) - VCC regulation 5 V ±5% on 2 × 100 n F or 1 × 100 n F and 1 × 220 n F multilayer ceramic capacitors with low ESR, ICC < 65 m A at 4.5 V < VDDP < 6.5 V, current spikes of 40 n As up to 20 MHz, with controlled rise and fall times, filtered overload detection approximately 90 m A) - 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, card take-off, overheating or supply drop-out) - Enhanced ESD protection on card side (>6 k V) - 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 - Supply supervisor for spikes killing during power-on and power-off - One multiplexed status signal OFF. APPLICATIONS - IC card readers for banking - Electronic payment - Identification - Pay TV. GENERAL DESCRIPTION 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.
