Low power 3V smart card interface

Supporting asynchronous cards (microcontroller-based IC cards), the TDA8037 is a smart card interface device forming the electrical interface between a microcontroller and a smart card. It is the cost efficient successor of the established integrated contact smart card reader IC TDA8035.

The electrical characteristics of the TDA8037 are in accordance with CISCO technology requirements (IRD Electrical Interface Specifications doc n° LC-T056) and also comply with ISO7816-3 for class B.It offers a high level of security for the card performing current limitation, short circuit detection, ESD protection as well as supply supervision.
