Memory IC datasheet and documents for DS28E80Q+U

DS28E80Q+U

Memory IC Overview

The DS28E80Q+U is a gamma radiation-resistant, user-programmable nonvolatile memory chip featuring 248 bytes of storage organized into 31 blocks of 8 bytes. It communicates via the single-contact 1-Wire bus at standard (15.3kbps) or overdrive (76kbps) speeds. Each device contains a factory-programmed unique 64-bit registration number for node addressing. The operating voltage range is 2.97V to 3.63V, with an operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

Radiation-hardened storage cell technology resistant to gamma radiation up to 75kGy
Individual block write protection that cannot be reversed once activated
Each memory block supports eight reprogramming cycles
Integrated 16-bit CRC generation and verification for data integrity

Memory IC Applications

Identification of medical consumables
Identification and calibration of medical tools and accessories
Storage of manufacturing or calibration data prior to medical sterilization

Memory IC Procurement Notes

Verify the specific suffix 'Q' indicates qualified reliability standards and '+U' denotes the TDFN-EP package configuration. Confirm the component meets required radiation tolerance levels for intended sterilization processes. Ensure system pullup resistor values comply with the specified maximum resistance limits for reliable 1-Wire communication.

Memory IC Selection Notes

Select this component when radiation hardness is critical for applications involving repeated sterilization cycles. The 248-byte capacity and block-level protection suit small data storage needs. Verify compatibility with existing 1-Wire master controllers supporting standard and overdrive speeds. Consider the 6-pin TDFN package constraints for board layout and thermal management.

Memory IC Part Context

The DS28E80 belongs to the Maxim Integrated 1-Wire memory family, designed specifically for harsh environments. It utilizes a specialized storage cell technology distinct from floating-gate EEPROMs to withstand high-energy radiation. This series addresses the need for durable, programmable identification in medical and industrial sectors where standard memory would fail.
