Smart Card Applications

CryptoMemory offers the ability to communicate with virtually any smart card reader using the asynchronous T=0 protocol

defined in ISO 7816-3. For devices with 32-Kbit of user memory and larger, communication speeds up to 153,600baud are

supported by utilizing ISO 7816-3 protocol and parameter selection. All CryptoMemory devices in smart card module form will

also communicate using a synchronous 2-Wire serial interface.

Scope and Purpose of This Document

This document covers all three major operational modes of CryptoMemory



Standard Mode

Authentication Mode

Encryption Mode

This document provides all information necessary to take full advantage of the security capabilities of CryptoMemory. It is

designed for use in conjunction with functional cryptographic libraries or companion hardware from Atmel; therefore, requires

cryptographic library and or companion hardware documentation to complement its use. Contact your regional Atmel sales

office for information on the most current version of functional libraries and/or available cryptographic companion hardware.
