Description

General part information

ATAES132A Series

**Authorization, Key Management, and Memory Encryption**

The first device in the AES family, the ATAES132A, is a high-speed, high-security, 32K Serial EEPROM that enables authentication and confidential nonvolatile data storage. It is a direct drop-in for industry standard Serial EEPROMS and is an easy way to add security to a system. The ATES132A includes a high-quality hardware Random Number Generator (RNG) paired with a Federal Information Processing Standards (FIPS) Deterministic Random Bit Generator (DRBG) to prevent replay attacks.

This ATAES132A uses the industry standard Advanced Encryption Standard (AES) algorithm in the CCM mode (Counter and Cipher block chaining Message authentication code) making authentication, confidentiality, and data integrity checking easy.
