DS8314 - (DS8313 / DS8314) Smart Card Interface

This page provides the datasheet information for the DS8314, a member of the DS8313 (DS8313 / DS8314) Smart Card Interface family.

Description

The DS8313 smart card and SIM interface IC is a lowcost, analog front-end for a smart card reader designed for smart card applications that do not require the use of the auxiliary card I/O contacts C4 and C8 (AUX1 and AUX2).

The DS8313 supports 5V, 3V, and 1.8V smart cards.

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.

19-4655; Rev 1; 5/09 www.DataSheet4U.com Smart Card Interface General Description The DS8313 smart card and SIM interface IC is a lowcost, analog front-end for a smart card reader designed for smart card applications that do not require the use of the auxiliary card I/O contacts C4 and C8 (AUX1 and AUX2). The DS8313 supports 5V, 3V, and 1.8V smart cards. The absence of a charge pump reduces active power consumption, and the DS8313 also supports an ultra-low-power 10nA stop mode. The DS8313 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. The DS8314 is similar to the DS8313, but only uses one analog (smart card) power supply.
