TDA8024 is a smart card interface device making the electrical interface between a microcontroller and a smart card. This device supports mainly asynchronous cards (micro controller based IC cards).

This device a direct derivative of the TDA8004 and is pin to pin compatible (precautions have to be taken for PORadj pin).New features have been added in order to be compliant with EMV specification.

The electrical characteristics of TDA8024 are in accordance with NDS requirements (IRD Electrical Interface Specifications doc n LC-T056) but also comply with ISO7816-3 and E.M.V. (Europay, Mastercard, Visa) normalisation.

TDA8024 can be used in various applications such as pay-TV, point of sales terminals (P.O.S.), public phone, vending machines, and a lot of conditional access applications (i.e. internet ,...).

This device does not support smart cards with a programming voltage (VPP) greater than 5V, because new generation of IC cards does not need such a feature (EEPROM based smart cards).
