MR25H256AMDF

Memory IC Overview

The MR25H256AMDF is a non-volatile magnetic random-access memory (MRAM) integrated circuit manufactured by Everspin Technologies. It provides a storage capacity of 256 kilobits, organized as 32K words by 8 bits. The device utilizes a Serial Peripheral Interface (SPI) for communication and supports clock frequencies up to 40 MHz. It operates within a supply voltage range of 2.7 V to 3.6 V and is rated for an extended industrial temperature range from -40°C to +125°C. The component is housed in an 8-lead DFN package with exposed pad.

Memory IC Feature Summary

• Non-volatile data retention without requiring backup power sources
• High-speed serial SPI interface supporting up to 40 MHz operation
• Robust construction suitable for automotive applications under AEC-Q100 standards

Memory IC Applications

• Automotive electronic systems requiring high reliability
• Industrial control equipment operating in extreme temperatures
• Embedded systems needing fast write endurance and low power consumption

Memory IC Procurement Notes

Verify the specific suffix 'D' indicates the tape-and-reel or tray packaging configuration as defined by the manufacturer's current documentation. Confirm that the component meets RoHS3 compliance requirements for your region. Ensure the ordering quantity aligns with the manufacturer's standard packing unit to avoid partial shipment issues.

Memory IC Selection Notes

Select this part when non-volatility and high write endurance are critical compared to flash memory alternatives. The 256Kb capacity suits small data logging tasks. Verify that the system voltage remains within the 2.7V to 3.6V window. Consider the 8-DFN footprint constraints during PCB layout design.

Memory IC Part Context

This component belongs to the MR25H256 series of magnetoresistive RAM devices. It shares architectural similarities with other members like the MR25H128A but offers double the density. The technology replaces traditional EEPROM and Flash in applications demanding infinite write cycles and faster programming speeds.

Memory IC Replacement Considerations

The MR25H256ACDF is listed as a similar alternative within the same product family. Verify pin compatibility and electrical specifications before substitution. Other variants may differ in packaging type or temperature grade.
