ATECC108A-MAHDA-T Description

Short technical summary and product information.

The Microchip Technology ATECC108A-MAHDA-T is a CryptoAuthentication device featuring secure hardware-based key storage. It performs high-speed Public Key Infrastructure (PKI) algorithms such as ECDSA and the SHA-256 hash algorithm with an HMAC option. This device supports NIST standard elliptic curves P256, B283, and K283, with key lengths of 256-bit and 283-bit. It provides storage for up to 16 keys and includes a guaranteed unique 72-bit serial number.

Connectivity is handled via a high-speed single-pin interface with one GPIO pin or a 1MHz standard I2C interface. The device operates within a supply voltage range of 2.0V to 5.5V, with I/O levels from 1.8V to 5.5V. Its low sleep current is less than 150nA. The ATECC108A-MAHDA-T is available in an 8-pad UDFN package (2x3mm).

Applications for this authentication chip include secure download and boot, ecosystem control, message security for IoT nodes, and anti-cloning measures. It ensures that devices and code are genuine, untampered, and confidential, making it suitable for networking and communications applications.
