IC card interface

TDA8002

• Supply supervisor for spikes elimination and emergency

FEATURES

deactivation.

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

• Low-power sleep mode

APPLICATIONS

• Three specific protected half-duplex bidirectional

• IC card readers for:

– GSM applications

– banking

buffered I/O lines

• V_CCregulation (5 V ±5%, I_CC<65 mA at V_DD= 5 V, with

controlled rise and fall times

• Thermal and short-circuit protections with current

limitations

– electronic payment

– identification

– Pay TV

• Automatic ISO 7816 activation and deactivation

sequences

– road tolling.

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

• Clock generation for the card up to 12 MHz with

synchronous frequency changes

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.

• 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 V_CCgeneration
