DS28E84Q+U

Specialized ICS Overview

The DS28E84Q+U is a radiation-resistant secure authenticator featuring ECC-P256 and SHA-256 cryptographic engines. It integrates a FIPS-compatible TRNG, 10Kb OTP, 15Kb FRAM, and a unique 64-bit ROM ID. Operating on the 1-Wire interface with a 3.3V ±10% supply (2.97V to 3.63V), it supports standard and overdrive speeds. The device withstands up to 50kGy radiation, includes one configurable GPIO, and operates within a 0°C to +50°C temperature range in a 6-pin TDFN package.
