Description
- Overview
- 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 for the TDA8004AT.
- More information can be obtained from the NXP internet site (www.nxp.com) and from _“Application note AN10141”_.

- ## Features
- * IC card interface
- * 3 or 5 V supply for the IC (VDD and GND)
- * Three specifically protected half-duplex bidirectional buffered I/O lines to card contacts C4, C7 and C8
- * DC/DC converter for VCC generation separately powered from a 5 V +- 20 pct supply (VDDP and PGND)
- * 3 or 5 V +- 5 pct regulated card supply voltage ((VCC) with appropriate decoupling has the following capabilities:
- * ICC< 80 mA at VDDP = 4 to 6.5 V
- * Handles current spikes of 40 nAs up to 20 MHz
- * Controls rise and fall times
- * Filtered overload detection at approximately 120 mA
- * Thermal and short-circuit protection 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, VDD or VDDP drop-out
- * Enhanced ESD protection on card side (>6 kV)
- * 26 MHz integrated crystal oscillator
- * Clock generation for cards 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) compatibility
- * Supply supervisor for spike-killing during power-on and power-off and Power-on reset (threshold fixed internally or externally by a resistor bridge); not for TDA8024AT
- * Built-in debounce on card presence contacts
- * One multiplexed status signal OFF.
- ## Target Applications
- * IC card readers for banking
- * Electronic payment
- * Identification
- * Pay TV.
