产品概述

The DS8023-RJX+ from Maxim Integrated Products is a smart card interface IC in 28 pin TSSOP package. It a low cost, low power, analogue 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. It can often be used as a replacement for 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. It features high current/short circuit and high temperature protection. Typical applications include set-top box conditional access, access control, banking, POS terminals, debit/credit payment terminals, PIN pads, automated teller machines, telecommunications and pay/premium televisions.
  • Analogue interface and level shifting for IC card communication
  • ±8KV (min) ESD (IEC) protection on card interface pins, 20MHz external crystal frequency
  • Ultra low stop mode current is less than 10nA typically
  • Internal IC card supply voltage generation (5V ±5%, 80mA /3V ±8%, 65mA /1.8V ±10%, 30mA)
  • 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
  • Reset voltage thresholds of 2.45V (threshold voltage (falling)), 100mV (hysteresis)
  • 2.7V to 6V supply voltage, 215mA active VDD current 5V cards (including 80mA draw from 5V card)
  • Operating temperature range from -40°C to +85°C
