Product specification
TDA8002C
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
• V_CC regulation 5 V ±5% or 3 V ±5%, I_CC < 55 mA for
V_DD = 3.0 to 6.5 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

• Synchronous and asynchronous cards (memory and
smart cards)
• ISO 7816, GSM11.11 compatibility and EMV
(Europay, MasterCard® and Visa) compliant
• Step-up converter for V_CC generation
• Supply supervisor for spikes elimination and emergency
deactivation
• Chip select input for easy use of several TDA8002Cs in
parallel.
APPLICATIONS
IC card readers for:
• GSM applications
• Banking
• Electronic payment
• Identification
• Pay TV
• Road tolling.
GENERAL DESCRIPTION
The TDA8002C 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.
