MR25H128ACDFR

Memory IC Overview

The MR25H128ACDFR is a non-volatile magnetoresistive random-access memory (MRAM) integrated circuit manufactured by Everspin Technologies. It provides a storage capacity of 128 kilobits, organized as 16K words by 8 bits. The device operates with a supply voltage range of 2.7 V to 3.6 V and utilizes a Serial Peripheral Interface (SPI) for data communication. It is housed in an 8-lead Dual Flat No-Lead (DFN) package with an exposed pad, designed for surface-mount technology applications.

Memory IC Feature Summary

• Retains stored data without continuous power supply due to non-volatile magnetic storage technology
• Enables high-speed serial data transfer via standard SPI interface protocols
• Operates reliably across extended industrial temperature ranges

Memory IC Applications

• Data logging systems requiring persistent parameter storage
• Configuration memory for embedded controllers
• Industrial equipment needing reliable state retention

Memory IC Procurement Notes

Verify the specific suffix 'DFR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-DFN package dimensions align with the target printed circuit board footprint. Ensure the voltage specifications match the system power rails before integration.

Memory IC Selection Notes

Select this component when non-volatility is critical but flash endurance limits are insufficient. The MRAM technology offers unlimited write cycles compared to traditional EEPROM or Flash alternatives. Consider the SPI interface compatibility with existing microcontroller peripherals during system architecture planning.

Memory IC Part Context

This part belongs to the MR25H128A series of serial MRAM devices from Everspin Technologies. The series focuses on providing robust, high-endurance memory solutions for demanding environments where data integrity and speed are paramount. The DFN package variant facilitates compact design implementations.

Memory IC Replacement Considerations

Direct substitutes within the same family include the MR25H128ACDF, which differs primarily in tray packaging rather than electrical function. Verify pinout compatibility when transitioning between different packaging styles.
