TDA8034T/C1,112

TDA8034T/C1,112 is a smart card interface. It is a cost-effective analogue interface for asynchronous and synchronous smart cards operating at 5V or 3V. Using few external components, it provides all supply, protection and control functions between a smart card and the microcontroller. Application includes pay TV, electronic payment, identification, bank card readers.

• One protected half-duplex bidirectional buffered I/O line (C7)
• Thermal and short-circuit protection for all card contacts
• Enhanced card-side electro static discharge (ESD) protection of <gt/> 6kV
• External clock input upto 26MHz connected to pin XTAL1
• Non-inverted control of pin RST using pin RSTIN
• Compatible with ISO 7816, NDS and EMV 4.2 payment systems
• Built-in debouncing on card presence contacts (typically 4.5ms)
• Multiplexed status signal using pin OFFN
• Power supply voltage range from 4.85 to 5.5V (pin VDDP, VDDP = 5V, VDD = 3.3V)
• SO16 package, ambient temperature range from -25°C to +85°C
