Standard Smart Card Interface

Product Details

Block Diagram

Block diagram: TDA8024T, TDA8024TT

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.
