DS28E30X+T

Specialized ICS Overview

The DS28E30 is a 1-Wire ECDSA secure authenticator based on the FIPS-186 standard. It integrates an ECC P-256 compute engine, a true random number generator (TRNG), and 3Kb of secure EEPROM for storing keys and user data. The device features a unique factory-programmed 64-bit ROM ID and supports bidirectional asymmetric key authentication via challenge-response protocols. Operating at overdrive speeds up to 90.9kbps, it functions within a voltage range of 1.62V to 5.25V and an ambient temperature range of -40°C to +85°C.

Specialized ICS Feature Summary

• FIPS 186-4 compliant ECDSA signature generation using NIST P-256 curves
• Integrated TRNG for secure nonce generation during cryptographic operations
• 3Kb secure EEPROM with cryptographically protected read/write access
• Unique 64-bit factory-programmed ROM ID serving as electronic serial number

Specialized ICS Applications

• Battery authentication and charge cycle tracking
• Medical tool and accessory authentication
• Peripheral secure authentication in multidrop networks
