Errata
  • Errata DS8024 8024A4.pdf 

    • Description
    The DS8024 smart card interface IC is a low-cost, analog front-end for a smart card reader, designed for all ISO 7816, EMV*, and GSM11-11 applications. The DS8024 is a pin-for-pin drop-in replacement for the NXP TDA8024 and is offered in 28-pin TSSOP and SO packages.

    Applications requiring support for 1.8V smart cards or requiring low power should consider the DS8113, which achieves lower active- and stop-mode power with minimal changes to application hardware and software.

    Key Features   Applications/Uses
    • Analog Interface and Level Shifting for IC Card Communication
    • 8kV (min) ESD (IEC) Protection on Card Interfaces
    • Internal IC Card Supply-Voltage Generation:
      • 5.0V ±5%, 80mA (max)
      • 3.0V ±8%, 65mA (max)
    • Automatic Card Activation and Deactivation Controlled by Dedicated Internal Sequencer
    • I/O Lines from Host Directly Level Shifted for Smart Card Communication
    • Flexible Card Clock Generation, Supporting External Crystal Frequency Divided by 1, 2, 4, or 8
    • High-Current, Short-Circuit and High-Temperature Protection
