TDA8037 Overview
Description
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.
Key Features
- Thermal and short-circuit protection on all card contacts
- Enhanced card-side ElectroStatic Discharge (ESD) protection of (> 8 kV)
- SW compatible to TDA8024, TDA8034 and TDA8035
- 3 V smart card supply
- Three protected half-duplex bidirectional buffered I/O lines (C4, C7 and C8)
- External clock input up to 20 MHz
- Card clock generation up to 20 MHz using pin CLKDIV with synchronous frequency changes of fCLKIN, fCLKIN/2 (with SO28 package only)
- Non-inverted control of pin RST using pin RSTIN
- Built-in debouncing on card presence contact
- Multiplexed status signal using pin OFFN
