MR25H256ACDFR

Memory IC Overview

The MR25H256ACDFR is a magnetoresistive random-access memory (MRAM) device manufactured by Everspin Technologies. It offers a storage capacity of 256 kbit, organized as 32k x 8 bits with an 8-bit data bus width. The component utilizes a Serial Peripheral Interface (SPI) for communication and operates within a supply voltage range of 2.7 V to 3.6 V. It is housed in an 8-DFN package with exposed pad and supports surface mount installation. The device functions reliably across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Non-volatile magnetic storage technology providing unlimited write endurance without write delays.
• Serial SPI interface compatible with standard EEPROM and flash timing requirements.
• Robust construction suitable for high-reliability industrial and automotive environments.

Memory IC Applications

• Data logging and parameter storage in electric vehicle powertrains
• Industrial control systems requiring frequent data updates
• Consumer electronics needing reliable non-volatile configuration retention

Memory IC Procurement Notes

Verify the specific suffix 'ACDFR' against the manufacturer's current datasheet to confirm package dimensions and moisture sensitivity level. Ensure the ordering information matches the required reel or cut tape packaging format. Confirm RoHS compliance status and humidity sensitivity handling procedures prior to assembly to prevent damage during soldering processes.

Memory IC Selection Notes

Select this component when designing systems that require high-speed serial access combined with infinite endurance. It serves as a drop-in replacement for serial EEPROMs and Flash in applications where write cycles exceed typical limits. Consider the 8-DFN footprint and SPI compatibility when evaluating alternative memory solutions for space-constrained PCB layouts.

Memory IC Part Context

This part belongs to the MR25H256 series of serial MRAM devices from Everspin Technologies. These components are engineered to bridge the performance gap between volatile SRAM and traditional non-volatile memories. The series emphasizes durability and speed, making it distinct from standard flash-based storage solutions in the same package form factor.
