2.1 Embedded Applications
A 2-wire serial interface running at 1.0 MHz is used for fast and efficient communications with up
to 15 devices that may be individually addressed. CryptoMemory is available in industry stan-
dard 8-lead packages with the same familiar pinout as 2-wire serial EEPROM’s supporting only
the synchronous communications protocol.
2.2 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 32K bits 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.

2.3 Scope and Purpose of This Document
This document covers only the Standard Mode of operation of CryptoMemory. The other modes
of operation are the Authentication and Encryption Modes. This document provides all the infor-
mation needed to utilize CryptoMemory in the Standard Mode. The scoping of this document
allows for free distribution without formal requirements of any user agreements and serves the
purpose of developing applications using only the Standard Mode of operation. Documents con-
taining detailed description of the cryptographic technology, operation and function of the
Authentication and Encryption Modes of CryptoMemory are secure and so only available under
Non-Disclosure and Limited Licensing Agreements (NDA and LLA). Contact your regional
Atmel sales office to obtain these secure documents.
