DS8005 - Smart Card Interface

General Description

The DS8005 dual smart card interface is a low-cost, dual analog front-end for an IC card reader interface that needs to communicate with two smart cards in a mutually exclusive fashion.

The analog interface is designed for use in ISO 7816, EMV®, and B-CAS applications.

Key Features

  • Analog Interface and Level Shifting for IC Card Communication.
  • ±8kV (min) ESD (HBM) Protection on Card Interfaces.
  • Ultra-Low Stop-Mode Current, Less than 10nA Typical.
  • Internal IC Card Supply-Voltage Generation 5.0V ±5%, 80mA (max) 3.0V ±8%, 65mA (max) 1.8V ±10%, 30mA (max).
  • Automatic Card Activation and Deactivation Controlled by Dedicated Internal Sequencer.
  • I/O Lines from Host Directly Level Shifted for Smart Card Communication.

19-5257; Rev 0; 4/10 www.DataSheet4U.com Smart Card Interface General Description The DS8005 dual smart card interface is a low-cost, dual analog front-end for an IC card reader interface that needs to communicate with two smart cards in a mutually exclusive fashion. The analog interface is designed for use in ISO 7816, EMV®, and B-CAS applications. The device is functionally similar to two DS8024s with external multiplexing to select the active interface, but also includes low power and 1.8V card support. Additionally, the device is designed for applications where the C4/C8 (AUX1/AUX2) contacts are not required on either card interface. The device is provided in a 28-pin SO package.
