Memory IC datasheet and documents for DS2501S-UNW-111B/T&R

DS2501S-UNW-111B/T&R

Memory IC Overview

The DS2501S-UNW-111B/T&R is a 1-Wire EEPROM memory IC manufactured by Analog Devices Inc./Maxim Integrated. It provides 512 bits of serial number and user-accessible data storage within a compact UNW package. The device utilizes the proprietary 1-Wire communication protocol for data transfer, requiring only a single data line and ground connection. This component is designed for embedded applications where unique identification and small-scale data retention are required.

Memory IC Feature Summary

Integrates 512-bit EEPROM with factory-programmed 64-bit ROM serial number
Operates using the standard 1-Wire single-bus communication protocol
Available in a compact UNW surface-mount package

Memory IC Applications

Embedded system device identification
Product authentication and security
Development tool configuration storage

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS3 compliance and specific tape-and-reel packaging specifications before procurement. Ensure supply chain sources provide valid traceability documentation for quality assurance purposes.

Memory IC Selection Notes

Select this component when a unique hardware identifier is required for each unit in an assembly. The 1-Wire interface minimizes pin count compared to parallel or SPI alternatives. Consider the limited 512-bit capacity for simple configuration tasks rather than complex data logging requirements.

Memory IC Part Context

This part belongs to the DS2501 family of 1-Wire EEPROMs from Maxim Integrated, now part of Analog Devices. These devices are widely used for providing unique IDs to electronic components. The UNW suffix indicates a specific micro-package variant suitable for space-constrained printed circuit board designs.
