Description
AT83C21GC is designed to simplify the integration of smart card interfaces in elec- tronic devices. It manages the electrical interface and communication with ISO 7816 –1/2/3/4 com- patible smart cards and memory cards. Figure 1. Basic Architecture of a Smart Card Reader
4247AS–SCR–04/03 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. It 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. Enquiries can also be posted to cardreader@atmel.com.
