TDA8037T/C1Y

TDA8037T/C1Y is a low power 3V smart card interface. It is the cost efficient successor of the established integrated contact smart card reader IC TDA8035. It offers a high level of security for the card performing current limitation, short circuit detection, ESD protection as well as supply supervision. Operating in the 3V supply domain, the current consumption during the shutdown mode of the contact reader is very low. It is therefore the ideal component for a power-efficient contact reader. The application includes pay TV, electronic payment, identification, and IC card readers for banking.
