Low-Power IC Card Interface

TDA8023TT
No Longer Manufactured

The TDA8023 is a complete cost-efficient, low-power analog interface for synchronous or asynchronous smart cards. It can be placed between the card and the microcontroller with very few external components to perform all supply, protection and control functions.

Product Details

Features

  • I²C-bus controlled IC card interface in TSSOP28
  • Supply voltage from 2.7 V to 6.5 V
  • Independant supply voltage VDD(INTF) for interface signals with the microcontroller
  • Shutdown input for very low power consumption when the part is not used
  • Power reduction modes when the card is active
  • DC-to-DC converter for VCC generation (capacitive doubler, tripler, or inductive, or follower automatically selected according to supply voltage and card voltage)
  • 1 specific protected half duplex bidirectional buffered I/O line, with current limitation at ±15 mA, maximum frequency 1 MHz
  • 2 auxiliary card I/O lines controlled by I²C-bus (C4 and C8)
  • VCC regulation: 5 V, 3 V or 1.8 V ±8%, ICC< 55 mA, current spikes of 40 nAs up to 20 MHz, with controlled rise and fall times, filtered overload detection approximately 80 mA, current limitation about 120 mA
  • 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, VDD or VDD(DCDC) drop-out
  • Enhanced ElectroStatic Discharge (ESD) protection on card side (> 6 kV)
  • 20 MHz clock input
  • Clock generation for the card up to 10 MHz (CLKIN divided by 1, 2, 4 or 5) with synchronous frequency changes; stop HIGH or LOW or free running 1 MHz in cards Low-power mode; current limitation on pin CLK (C3)
  • RST signal (C2) with current limitation at 20 mA, controlled by an embedded programmable CLK pulse counter on asynchronous cards or by a register on synchronous cards
  • ISO 7816-3, GSM 11.11 and EMVCo 4.3 compatibility
  • Supply voltage supervisor for spike killing during power-on and emergency deactivation at power-off: threshold internally fixed or set via an external resistor bridge; pulse width internally fixed or set via an external capacitor
  • Card presence input with 10 ms built-in debouncing system
  • One interrupt signal INT
