UG_12xxF_018 Using Synchronous Smart Cards with the 73S12xxF
Rev. 1.0 5
1 Introduction
This document describes how to use synchronous smart cards with the 73S12xxF family. The smart card
block of the 73S12xxF family contains specific logic for running synchronous smart cards. There are
three primary sync smart card types; 2-wire, 3-wire and I
2
C smart cards. Each of these card types will be
described and how to operate these cards with the 73S12xxF sync card logic is detailed.
This document is intended for the application developer that needs to support synchronous smart cards.
Understanding of basic Smart Card operation is helpful and required. In addition, familiarity with the
Teridian 73S12xxF smart card block is assumed for Asynchronous smart card operation. Refer to the
73S12xxF data sheets for a detailed description of the smart card logic and control registers.
