产品概述

The 73S8010R-IM/F is a low cost smart card interface in 32 pin QFN package. It provides full electrical compliance with ISO-7816-3 and EMV 4.0 (EMV2000) specifications. Interfacing with host is done through two wire I2C bus and one interrupt output to inform system controller of card presence and faults. It incorporates an ISO-7816-3 activation/deactivation sequencer that controls card signals. Level shifters drive card signals with selected card voltage (3V or 5V) coming from an internal low dropout voltage regulator. This LDO regulator is powered by dedicated power supply input (VPC). Digital circuitry is separately powered by digital power supply (VDD). The 73S8010R is a cost effective solution for any application where 5V (typically -5% +10%) power supply is available with its embedded LDO regulator. Hardware support for auxiliary I/O lines, C4/C8 contacts is provided. Emergency card deactivation is initiated upon card extraction or upon any fault generated by protection circuitry.
  • Supply voltage from 2.7V to 5.5V (VDC) and 4.75V to 5.5V (VPC)
  • Operating temperature range from -40°C to 85°C
  • Traditional step-up converter is replaced by an LDO regulator and true card overcurrent detection
  • LDO voltage regulator provides 3V/5V to card from an external power supply input
  • Overcurrent detection of 150mA
  • One control register, one status register and interrupt output to host for fault detection
  • 6KV ESD protection on the card interface
  • Crystal oscillator or host clock, up to 27MHz Interrupt output to host for fault detection
  • True card overcurrent detection
