TDA8037TT: 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.

  • 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)

  • 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)

  • TSSOP16 and SO28 package
  • SO28 version is footprint compatible with TDA8024T
  • Compliant with ISO 7816, Cisco technology and EMV 4.3 payment systems
