DS28E16G+T

Specialized ICS Overview

The DS28E16G+T is a secure authenticator integrating FIPS 202-compliant SHA-3 challenge-response authentication with secured EEPROM. It features a SHA-3 engine, 256 bits of user EEPROM, a decrement-only counter, and a unique 64-bit ROM ID. Operating on the single-contact 1-Wire bus, it supports overdrive speeds up to 90.9 kbps. The device operates within a voltage range of 1.71V to 3.63V and an ambient temperature range of -40°C to +85°C. Typical input load current is 3.5µA, with a maximum of 11µA. It provides ±8kV HBM ESD protection and utilizes internal parasite power capacitance.

• Unique factory-programmed 64-bit ROM ID serving as electronic serial number
• 17-bit nonvolatile decrement-only counter with authenticated read capability

Specialized ICS Applications

• Medical tools and accessories authentication and calibration
• Accessory and peripheral secure authentication
• Battery authentication and charge cycle tracking

Specialized ICS Procurement Notes

Verify the specific package variant against project requirements. The 'G' suffix denotes the SFN (3.5mm x 6.5mm) package. Confirm that the component is qualified for electro-mechanical contact use cases only, as soldering is not supported for this package type. Ensure the ordering suffix matches the desired tape and reel quantity of 2,500 pieces.

Specialized ICS Selection Notes

Select the DS28E16G+T when a robust anti-tamper solution is required for peripherals using a single-contact interface. The SFN package is suitable for applications requiring physical durability through mechanical contacts rather than PCB soldering. Verify system pullup resistance does not exceed 750Ω and that the host controller supports the 1-Wire protocol timing constraints for reliable communication.

Specialized ICS Part Context

This component belongs to the DS28E16 family of 1-Wire Secure SHA-3 Authenticators from Analog Devices/Maxim Integrated. The family includes variants such as DS28E16X (WLP), DS28E16Q (TDFN-EP), and DS28E16GA (SFN 3.5mm x 5mm). All variants share identical core cryptographic functionality but differ in physical packaging and thermal characteristics.

Specialized ICS Replacement Considerations

Direct pin-compatible replacements within the same family include DS28E16Q+T (TDFN-EP) and DS28E16GA+T (SFN 3.5mm x 5mm). Substitution requires verifying that the alternative package meets the mechanical constraints of the enclosure or connector interface.
