DS8023 - Smart Card Interface

General Description

The DS8023 smart card interface IC is a low-cost, lowpower, analog front-end for a smart card reader designed for all ISO 7816, EMV

, and GSM11-11 applications.

The DS8023 supports 5V, 3V, and 1.8V smart cards, and provides an option for ultra-low stop-mode power consumption.

Key Features

  • Analog Interface and Level Shifting for IC Card Communication.
  • ±8kV (min) ESD (IEC) Protection on Card Interface Pins.
  • Ultra-Low Stop-Mode Current, Less Than 10nA (typ).
  • 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.

Rev 0; 8/08 www.DataSheet4U.com Smart Card Interface General Description The DS8023 smart card interface IC is a low-cost, lowpower, analog front-end for a smart card reader designed for all ISO 7816, EMV*, and GSM11-11 applications. The DS8023 supports 5V, 3V, and 1.8V smart cards, and provides an option for ultra-low stop-mode power consumption. The DS8023 is available in 28-pin TSSOP and SO packages, and can often be used as a replacement for the TDA8024 with little or no application changes. The DS8023 is designed to interface between a system microcontroller and the smart card interface, providing all power supply, protection, and level shifting required for IC card applications.
