IC card interface

TDA8002

FEATURES

• Single supply voltage interface (3.3 or 5 V environment)

• Low-power sleep mode

• Three specific protected half-duplex bidirectional

buffered I/O lines

• VCC regulation (5 V ±5%, ICC <65 mA at VDD = 5 V, with

controlled rise and fall times

• Thermal and short-circuit protections with current

limitations

• Automatic ISO 7816 activation and deactivation

sequences

• Enhanced ESD protections on card side (>6 kV)

• Clock generation for the card up to 12 MHz with

synchronous frequency changes

• Clock generation up to 20 MHz (auxiliary clock)

• Synchronous and asynchronous cards (memory and

smart cards)

• ISO 7816, GSM11.11 compatibility and EMV (Europay,

Mastercard, Visa) compliant

• Step-up converter for VCC generation

• Supply supervisor for spikes elimination and emergency

deactivation.

APPLICATIONS

• IC card readers for:

– GSM applications

– banking

– electronic payment

– identification

– Pay TV

– road tolling.

GENERAL DESCRIPTION

The TDA8002 is a complete low-power, analog interface

for asynchronous and synchronous cards. It can be placed

between the card and the microcontroller. It performs all

supply, protection and control functions. It is directly

compatible with ISO 7816, GSM11.11 and EMV

specifications.
