Product Details
ATECC608B-RBHCZ-B - ECC CryptoAuthentication Secure Element
ATECC608B-RBHCZ-B from Microchip Technology is a three-contact hardware secure element with protected key storage, ECDSA, ECDH, SHA-256, AES-128 and a Single-Wire Interface.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
ATECC608B stores private keys in protected hardware and performs elliptic-curve, SHA-256, AES and random-number operations without exposing secrets to the host.
Key Advantages
Three-contact packaging supports compact accessory and consumable authentication assemblies.
Hardware cryptography and protected slots simplify device identity and mutual authentication.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
