ATECC608B-SSHDA-T MICROCHIP Specialized ICs

The ATECC608B-SSHDA-T is a cryptographic co-processor from Microchip with hardware-based key storage, protecting up to 16 keys or certificates and offloading ECDSA/ECDH, SHA-256, and AES-128 operations onto dedicated silicon. For selection, verify a supply of 2.0V–5.5V (1.8V–5.5V I/O), an I2C or single-wire host interface, and the -40°C to +85°C industrial range with 150 nA sleep current. Typical applications include IoT node authentication, secure boot/firmware validation, TLS 1.2/1.3 networking key management, consumable authentication, and over‑the‑air update protection for industrial and medical devices.
