DS28E83Q+U

Specialized ICS Overview

The DS28E83Q+U is a radiation-resistant secure authenticator featuring ECC P-256 and SHA-256 cryptographic engines. It includes a FIPS-compatible TRNG, 10Kb secured OTP, and a configurable GPIO. Operating at 3.3V ±10% (2.97V to 3.63V), it supports standard and overdrive 1-Wire speeds. The device withstands up to 75kGy radiation, operates from 0°C to +50°C, and provides ±8kV HBM ESD protection on the IO pin.

Specialized ICS Feature Summary

• Radiation resistance up to 75kGy for post-manufacturing sterilization
• Integrated ECC P-256 and SHA-256 compute engines with FIPS compliance
• 10Kb One-Time Programmable (OTP) memory for keys and certificates
• FIPS true random number generator (TRNG) with NIST SP 800-90B entropy

Specialized ICS Applications

• Medical consumables secure authentication
• Medical tools and accessories identification
• Secure boot of host processors via GPIO control
• Secure storage of cryptographic keys for host controllers

Specialized ICS Procurement Notes

Verify package type upon ordering; 'U' suffix indicates TDFN-6 requiring external capacitor CX, while 'G' indicates SFN with embedded capacitor. Confirm radiation tolerance requirements match the 75kGy specification. Ensure system pull-up voltage remains within 2.97V to 3.63V limits.

Specialized ICS Selection Notes

Select this component when high radiation hardness is required alongside asymmetric authentication. The TDFN package requires an external 470nF capacitor (CX). Verify that the operating temperature range of 0°C to +50°C meets environmental constraints.

Specialized ICS Part Context

Part of the DeepCover family designed for secure authentication in harsh environments. It integrates hardware crypto engines to protect sensitive data against invasive and noninvasive attacks using active die shielding and encrypted storage.

Specialized ICS Replacement Considerations

No direct public substitutes are listed. Alternative solutions must provide equivalent 75kGy radiation resistance and ECC P-256/SHA-256 capabilities.
