MR25H10MDFR

Memory IC Overview

The MR25H10MDFR is a magnetoresistive random access memory device with a capacity of 1 Mbit, organized as 128K x 8 bits. It operates on a serial SPI interface with a maximum clock rate of 40 MHz. The supply voltage range is 2.7 V to 3.6 V. The component supports industrial temperature ranges and features low current sleep mode. It is housed in an 8-pin DFN package with a reduced exposed pad size, suitable for surface mount applications.

Memory IC Feature Summary

• Provides unlimited write endurance without write delays, serving as a direct replacement for serial EEPROM and Flash memories.
• Includes automatic data protection mechanisms during power loss events to ensure data integrity.
• Supports block write protection capabilities alongside fast, simple serial peripheral interface communication.

Memory IC Applications

• Data logging systems requiring high endurance and non-volatile storage
• Configuration storage in consumer electronics and appliances
• Automotive embedded systems meeting AEC-Q100 Grade 1 standards

Memory IC Procurement Notes

Verify the specific suffix designation against official Everspin documentation to confirm package type and moisture sensitivity level. Confirm availability status as components may be subject to production lifecycle changes or minimum order quantity constraints depending on the distributor channel.

Memory IC Selection Notes

Select this component when designing systems that require frequent write cycles without degradation, unlike traditional flash technologies. Ensure the design accommodates the 2.7 V to 3.6 V operating range and utilizes the SPI interface timing specifications for reliable data transfer at up to 40 MHz.

Memory IC Part Context

This part belongs to the MR25H10 series of serial MRAM devices from Everspin Technologies. The series is characterized by its spin-transfer torque technology, offering non-volatile storage with RAM-like speed and endurance. The MR25H10MDFR specifically denotes the reel packaging variant of the 1 Mbit density option within this family.

Memory IC Replacement Considerations

MR25H10MDF is the tray-packaged equivalent of this component. Other MR25H10 variants with different suffixes may offer alternative packaging or temperature grades; verify datasheet compatibility before substitution.
