This application note by NXP Semiconductors deals with the dual smart card interface integrated circuit TDA8020HL/C2. The general characteristics are presented and different application examples are described.

TDA8020HL/C2 is a dual smart card interface device making the electrical interface between a microcontroller and two smart cards. This device supports mainly asynchronous smart cards (microcontroller-based IC cards).

The electrical characteristics of TDA8020C2 are in accordance with ISO7816-3 and EMV 2000 (Europay, Mastercard, Visa) normalisation. TDA8020C2 can be used in various applications such as pay TV, point of sales terminals, and a lot of conditional access applications (i.e. internet...), and also for security access modules in banking applications. As it is a device working under a low voltage power supply, it can also be used in portable applications like electronic purse readers or wallets. This device does not support smart cards with a programming voltage greater than 5 V, because new generations of IC cards do not need such a feature (EEPROM-based smart cards).
