DS28E36Q+T

Specialized ICS Overview

The DS28E36Q+T is a DeepCover secure authenticator integrating ECC-P256 and SHA-256 cryptographic engines. It features an 8Kb secured EEPROM, a decrement-only counter, two configurable GPIO pins, and a unique 64-bit ROM ID. The device communicates via the single-contact 1-Wire bus at standard (11.7kbps) or overdrive (62.5kbps) speeds. Operating voltage ranges from 2.97V to 3.63V with a typical computation current of 7.5mA. It supports FIPS 186 ECDSA signature generation/verification, ECDH key exchange, and FIPS 198 HMAC functions within a 6-pin TDFN-EP package.
