DS2465P-W49+1T

Specialized ICS Overview

The DS2465P-W49+1T is a DeepCover Secure Authenticator manufactured by Analog Devices Inc./Maxim Integrated. It integrates a SHA-256 coprocessor with a 1-Wire Master Function, enabling secure cryptographic operations over the 1-Wire bus. The device provides bidirectional authentication and nonvolatile memory storage for application data. It operates within a supply voltage range of 2.97V to 3.63V and draws a maximum supply current of 750µA. Designed for industrial environments, it supports an operating temperature range from -40°C to +85°C. The component is housed in a compact 6-TSOC package, facilitating surface-mount integration into security-sensitive systems requiring robust identity verification and data protection.

Specialized ICS Feature Summary

• Integrates SHA-256 coprocessor for crypto-strong, bidirectional secure challenge-and-response authentication
• Functions as a 1-Wire Master to manage communication with downstream 1-Wire slave devices
• Includes factory-programmed unique 64-bit ROM identification number for electronic serial numbering
• Operates on a single signal line and ground, supporting power delivery via the data line

Specialized ICS Applications

• Secure device registration and identity management
• Authentication of peripheral components in embedded systems
• Protection of sensitive data in IoT networks
• Access control systems requiring hardware-based key storage

Specialized ICS Procurement Notes

Verify the specific suffix W49+1T against official manufacturer documentation to confirm tape-and-reel packaging and any variant-specific electrical tolerances. Confirm RoHS3 compliance status directly with the supplier. Check current availability as distribution status may vary. Ensure the source document explicitly lists this exact part number to avoid substitution errors with standard DS2465 variants.

Specialized ICS Selection Notes

Select this component when both 1-Wire master capabilities and SHA-256 authentication are required in a single IC. Verify that the system voltage aligns with the 2.97V to 3.63V operating range. Ensure the PCB layout accommodates the 6-TSOC package dimensions. Consider the 750µA supply current for power budget calculations in battery-operated applications. Confirm compatibility with existing 1-Wire network protocols.
