The Microchip Technology ATAES132A-SHEQ-T is a high-security serial EEPROM designed for authentication and non-volatile data storage. It offers 32Kb of memory, compatible with standard serial EEPROMs, and incorporates an AES algorithm with 128-bit keys for robust security.
Key security features include secure hardware-based key storage for up to sixteen 128-bit keys, AES-CCM for authentication, and Message Authentication Code (MAC) capability. The device supports encrypted user memory read and write operations and includes a FIPS-compliant random number generator. It is configurable with 16 user zones, each 2Kb, offering flexible access rights including read/write, encrypted, or read-only options.
Connectivity is provided via a high-speed 10MHz SPI interface (Modes 0 and 3) or a 1MHz standard I2C interface. The ATAES132A-SHEQ-T operates within a supply voltage range of 2.5V to 5.5V and consumes less than 250nA in sleep mode. It is available in an 8-lead SOIC package and operates across a temperature range of -40°C to +85°C.
This component is suitable for applications requiring secure authentication of consumables, components, and network access, protection of sensitive firmware, secure data storage, and prevention of cloning. Its pinout compatibility with standard serial EEPROMs allows for easy integration into existing designs.
