Product Details
ATECC508A-SSHCZ-T - CryptoAuthentication Secure Element
ATECC508A-SSHCZ-T from Microchip Technology is a hardware cryptographic coprocessor with protected key storage, ECDSA authentication and a single-wire interface in 8-SOIC.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
ATECC508A stores private keys in tamper-resistant hardware and performs elliptic-curve authentication operations without exposing secrets to the host processor.
Key Advantages
Protects device identity and private keys in dedicated secure hardware.
Offloads ECDSA authentication, SHA-256 and key agreement from the host MCU.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
