TDA8002C - NXP

TDA8002C IC card interface

APPLICATIONS IC card readers for: • GSM applications • Banking • Electronic payment • Identification • Pay TV • Road tolling. GENERAL DESCRIPTION TDA8002C 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 fun.

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.
