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.

AES Algorithm with 128-bit Keys

AES-CCM for Authentication

Secure Storage for 16 and 128 bit Keys

Encrypted User Memory Read and Write

FIPS Random Number Generator (RNG)

16 High-Endurance Monotonic EEPROM Counters

Authentication Prior to Zone Access

Read/Write, Encrypted, or Read-only User Zone Options

Serial EEPROM Compatible Pinout (SOIC, SOP, or UDFN)

Easily Add Security by Replacing Existing Serial EEPROM
