ATECC508A-MAHCZ-T from Microchip Technology is a hardware cryptographic coprocessor with protected key storage, ECDSA, ECDH, SHA-256 and a single-wire host interface.
Specifications were checked against the manufacturer data sheet and current distributor listing.
ATECC508A protects private keys in dedicated hardware and performs elliptic-curve, SHA-256 and random-number operations for embedded identity and secure communication.
Private keys remain inside the secure element during signing and key agreement.
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.
Hardware-rooted authentication, key agreement and secure key storage
Single-Wire Interface for the CZ order code
2.0 V to 5.5 V; -40 C to +85 C; single-wire interface
8-UFDFN Exposed Pad
This ordering code uses the 8-UFDFN Exposed Pad package.

Confirm exact numbering and the latest land pattern before PCB release.
