Description

AT83C21GC is designed to simplify the integration of smart card interfaces in electronic devices.

AT83C21GC manages the electrical interface and communication with ISO 7816 1/2/3/4 compatible smart cards and memory cards.The connection with the host processor is achieved via a serial asynchronous link; the rate can be selected from a range from 1200 to 115,200 bps.The software inside the GemCore chip handles a communication protocol with the host system called the Gemplus Block Protocol (GBP).

A complete set of documentation is available on the Gemplus web site: http://www.gemplus.com.A GBP Interface Library Kit can be provided, upon request. AT83C21GC consists of the source code of the GBP communication layer between the host and GemCore. It is written in the C language. See the Gemplus developers' site at www.gemplus.com.
