DS28E02P-W10+1

Memory IC Overview

The DS28E02P-W10+1 is a 1-Kb EEPROM from the DS28E02 series, featuring integrated SHA-1 authentication for secure data storage. It operates on a single 1-Wire bus interface with supply voltages ranging from 1.75V to 3.65V. The device supports page write operations with a cycle time of 25ms and functions within an ambient temperature range of -20°C to +85°C. Packaged in a compact 6-TSOC format, it ensures reliable performance for embedded security applications requiring authenticated memory access.

Memory IC Feature Summary

• Integrates SHA-1 cryptographic engine for hardware-based authentication
• Utilizes single-wire serial communication protocol for simplified interfacing
• Provides electrically erasable programmable non-volatile storage capacity
• Operates efficiently across wide voltage ranges suitable for low-power systems

Memory IC Applications

• Secure identification tags and smart labels
• Authentication modules for consumer electronics
• Data integrity verification in industrial control systems
• Access control devices requiring encrypted memory storage

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to high counterfeit risk in security ICs. Confirm RoHS compliance status and specific suffix variations such as W10 for tape-and-reel packaging if required. Request original manufacturer documentation to validate SHA-1 implementation integrity before integration into safety-critical designs.

Memory IC Selection Notes

Select this model when SHA-1 based authentication is sufficient for the application security level. Consider alternative DeepCover devices if SHA-256 support or enhanced physical security mechanisms are necessary. Ensure the 6-TSOC package fits the PCB layout constraints and verify that the 1-Wire interface compatibility matches the host microcontroller capabilities.

Memory IC Part Context

This component belongs to the DS28E02 family of 1-Wire authenticated EEPROMs designed by Analog Devices/Maxim Integrated. It shares architectural similarities with the DS28E01 and DS28E07 models but offers specific storage and authentication configurations tailored for cost-effective security implementations in mass-produced electronic goods.

Memory IC Replacement Considerations

Direct substitutes include DS28E02P+ and DS28E02P-W10+T. Verify pinout compatibility and electrical specifications before substitution. Alternative security ICs may require firmware adjustments due to differences in command sets or authentication protocols.
