without the need for a microprocessor operating system. The embedded cryptographic engine provides for a dynamic,
symmetric mutual authentication between the device and host, as well as performs stream encryption for all data and
passwords exchanged between the device and host. Up to four unique key sets are available for these operations.
Embedded Applications
A 2-wire serial interface running at 1.0MHz is used for fast and efficient communications with up to 15 devices that may
be individually addressed. CryptoMemory is available in industry standard 8-lead packages with the same familiar
pinout as 2-wire serial EEPROM’s supporting only the synchronous communications protocol.
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-Kbits of user memory and larger, communication speeds up to
153,600 baud 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, namely Standard, Authentication, and
Encryption Modes. 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. It therefore requires cryptographic library and or companion hardware documentation to complement its
use. Please, contact your regional Atmel sales office for information on the most current version of functional libraries
and/or available cryptographic companion hardware.
