TDA8004AT 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 or 3 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) with synchronous frequency changes - 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. ORDERING INFORMATION TYPE NUMBER TDA8004AT PACKAGE NAME SO28 DESCRIPTION plastic small outline package; 28 leads; body width 7.5 mm APPLICATIONS - IC card readers for banking - Electronic payment - Identification - Pay TV. GENERAL DESCRIPTION The TDA8004AT is a plete low cost analog interface for asynchronous 3 or 5 V smart cards. It can be placed between the card and the microcontroller with very few external ponents to perform all supply protection and control functions.
