Microchip 8-Pin Crypto Authentication IC SOIC ATECC608B-SSHDA-B

Microchip ATECC608B-SSHDA-B is a high-security 8-pin crypto authentication IC designed for robust hardware-based key management and encryption. It combines hardware key storage with advanced cryptographic accelerators supporting industry-standard digital signatures and symmetric algorithms, making it suitable for industrial, IoT, automotive, and embedded systems requiring secure authentication and encrypted communication.

The device supports protected storage for up to 16 keys, certificates, or data with advanced hardware acceleration for ECDSA FIPS186-3 elliptic curve digital signatures and NIST P256 elliptic curve algorithms. With hardware support for SHA-256, HMAC, and AES-128 encryption/decryption, the ATECC608B enhances secure communication protocols including TLS 1.2 and 1.3 key derivation and ephemeral key generation.

Equipped with an internal NIST SP 800-90A/B/C compliant high-quality random number generator and dual high endurance monotonic counters, this Microchip IC ensures secure boot capabilities with full ECDSA code signature validation and optional communication key disablement prior to secure boot.

The compact surface mount SOIC package with dimensions 6 mm length, 1.75 mm width, and 4.9 mm height allows for easy integration on PCB designs requiring secure microcontroller authentication solutions. It operates reliably across a temperature range of -40°C to 100°C and supports a maximum supply voltage of 5.5 V.
