DS28E15P-W49+1T

Specialized ICS Overview

The DS28E15P-W49+1T is a DeepCover Secure Authenticator manufactured by Analog Devices Inc. (Maxim Integrated). It integrates 512-bit EEPROM with SHA-256 cryptographic capabilities on a single 1-Wire interface. The device operates within a supply voltage range of 2.97 V to 3.63 V and features a TSOC-6 surface-mount package. It supports data retention for up to 10 years and functions reliably across an industrial temperature range from -40°C to +85°C. Active read current is limited to a maximum of 1 mA, ensuring low power consumption during operation.

Specialized ICS Feature Summary

• Integrated 512-bit EEPROM organized as 256 x 2 bits
• Built-in SHA-256 hardware engine for secure authentication
• Single-contact 1-Wire interface for communication
• TSOC-6 surface-mount package configuration

Specialized ICS Applications

• Secure medical sensor authentication
• Consumable tracking in healthcare devices
• Industrial equipment component verification

Specialized ICS Procurement Notes

Verify the specific suffix W49 against official Analog Devices documentation to confirm its exact meaning regarding packaging or tape-and-reel specifications. Confirm availability status directly with authorized distributors, as supply constraints may apply to this specific variant. Ensure compliance with RoHS directives before procurement.

Specialized ICS Selection Notes

Select this component when SHA-256 security is required alongside nonvolatile memory in a compact form factor. The 512-bit capacity suits applications needing small data storage with high-security authentication. Verify that the system design supports the 1-Wire protocol and provides the necessary 2.97 V to 3.63 V operating voltage range.

Specialized ICS Part Context

This part belongs to the DS28E15 series of DeepCover Secure Authenticators. It shares core cryptographic and memory features with variants like the DS28E15G+T but differs in package type, utilizing the TSOC-6 format instead of the SFN-2 package found in other series members.

Specialized ICS Replacement Considerations

The DS28E15P+T is a verified substitute within the same series offering identical electrical and functional characteristics in the same TSOC-6 package.
