Simplifying System Integration™
DATA SHEET
April 2009
DESCRIPTION The Teridian 73S8024C is a single smart card interface IC. It provides full electrical compliance with ISO-7816-3, EMV 4.0 and NDS specifications1. Interfacing with the system controller is done through the control bus, composed of digital inputs to control the interface, and one interrupt output to inform the system controller of the card presence and faults. Data exchange with the card is managed from the system controller using the I/O line (and eventually the auxiliary I/O lines). Hardware support for auxiliary I/O lines, C4 / C8 contacts, is provided.
