NXP Semiconductors TDA8037
The TDA8037 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. It is therefore the ideal component for a power efficient contact reader.| Part No. | TDA8037 |
