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.

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% or 3 V ±5%, ICC < 55 mA for VDD = 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
• Clock generation up to 20 MHz (external clock)
• Synchronous and asynchronous cards (memory and smart cards)
• ISO 7816, GSM11.11 compatibility and EMV (Europay, MasterCard and Visa) compliant
• Step-up converter for VCC 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.
