• 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
• 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
– 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 VCC generation
