Product Details
DS28E40ATB/VY+ - DS28E40 Automotive 1-Wire ECC Authenticator
DS28E40ATB/VY+ from Analog Devices Inc./Maxim Integrated is an automotive P-256 secure authenticator with SHA-256, TRNG, protected memory and authenticated GPIO over 1-Wire.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
DS28E40 provides ECDSA signing and verification, ECDH key exchange, HMAC-SHA-256, encrypted memory and authenticated GPIO for automotive component trust.
Key Advantages
P-256 hardware and protected keys authenticate components without exposing private credentials.
Single-contact 1-Wire reduces interconnect while supporting secure boot and protected data.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
