Low-Power 3V Smart Card Interface
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. Operating in 3 V 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.

Product Details
Features
Protection of the contact smart card
- Thermal and short-circuit protection on all card contacts
- VCC regulation:
- 3 V ± 5 % on 2 × 220 nF multilayer ceramic capacitors with low ESR
- Current spikes of 40 nA up to 20 MHz, with controlled rise and fall times, filtered overload detection approximately 120 mA
- Automatic activation and deactivation sequences initiated by software or by hardware in the event of a short-circuit, card take-off, overheating, VDDhost, VREG and VDD dropping
- Enhanced card-side ElectroStatic Discharge (ESD) protection of (> 8 kV)
- Supply supervisor for killing spikes during power on and off:
- threshold internally fixed
- externally by a resistor bridge (with SO28 package only)
Easy integration into your contact reader
- 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
- Chip Select digital input for parallel operation of several TDA8037 ICs (with SO28 package only)
Other
