DS28C50Q+T

Specialized ICS Overview

The DS28C50Q+T is a DeepCover I2C secure authenticator integrating FIPS 202-compliant SHA-3 challenge-response authentication with ChipDNA physically unclonable function (PUF) technology. It operates on an I2C network at clock frequencies up to 1MHz, utilizing a supply voltage range of 2.97V to 3.63V. The device includes a 2Kb secured EEPROM array, a decrement-only counter, and a unique 64-bit ROM identification number. Active communication current reaches a maximum of 10mA, while standby current is limited to 400μA.

Specialized ICS Feature Summary

• Integrates ChipDNA PUF for hardware-level security against probing and cloning attacks
• Implements FIPS 202-compliant SHA-3 algorithm for challenge/response authentication
• Includes FIPS/NIST compliant true random number generator (TRNG)
• Features 2Kb secured EEPROM and a 17-bit decrement-only counter

Specialized ICS Applications

• Authentication of medical sensors and tools
• Secure management of limited-use consumables
• IoT node crypto-protection
• Printer cartridge identification and authentication

Specialized ICS Procurement Notes

Verify the component matches the specific ordering suffix 'Q' for industrial temperature range (-40°C to +85°C) and '+T' for tape-and-reel packaging configuration. Confirm that the supplier provides documentation verifying RoHS compliance, as indicated by the '+' designation in the part number. Ensure the source material explicitly supports the availability status for this specific reel quantity.

Specialized ICS Selection Notes

Select this component when I2C interface compatibility is required alongside high-assurance cryptographic protection. The device supports standard mode and fast mode operations up to 1MHz. Designers must account for the exposed pad thermal requirement and ensure pull-up resistors are connected to VCC for both SDA and SCL lines. Verify system power constraints align with the 2.97V to 3.63V operating range.

Specialized ICS Part Context

This part belongs to the Maxim Integrated DeepCover family of secure authenticators. It utilizes patented ChipDNA technology to generate unique, repeatable output values based on semiconductor fabrication variations. The device serves as a core security element for applications requiring tamper resistance and data integrity without relying solely on software-based encryption.

Specialized ICS Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative DeepCover models such as the DS28E39 or DS28EL15 if SHA-256 or different memory configurations are acceptable, noting that interface protocols and pinouts may differ.
