DS28C36Q+U

Specialized ICS Overview

The DS28C36Q+U is a DeepCover secure authenticator integrating asymmetric (ECC-P256) and symmetric (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 supports FIPS 186 ECDSA signature generation/verification and FIPS 180 HMAC operations via I2C at up to 1MHz. Operating voltage ranges from 2.2V to 3.63V within a -40°C to +85°C temperature range.
