TDA8002 Description
The TDA8002 is a plete 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.
TDA8002 Key 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%, ICC <65 mA at VDD = 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 (auxiliary clock)
- Synchronous and asynchronous cards (memory and smart cards)
TDA8002 Applications
- IC card readers for
