ATAES132A-SHEQ-T from Microchip Technology is a high-security serial EEPROM with AES-128 CCM authentication and encrypted data storage.
Specifications were checked against the manufacturer data sheet and current distributor listing.
ATAES132A combines 32 Kbits of EEPROM, protected key storage, AES-CCM authentication, encrypted reads and writes, counters and a hardware random-number generator.
Protects 16 user zones with AES-128 CCM authentication.
Adds encrypted storage in an EEPROM-compatible 8-pin footprint.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
