MR25H128APDF

Memory IC Overview

The MR25H128APDF is a magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It features a storage capacity of 128 kilobits organized as 16k x 8 bits. The component 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 DFN package designed for surface mount technology.

Memory IC Feature Summary

• Non-volatile data retention utilizing spin-transfer torque magnetic tunnel junction technology
• Serial SPI interface compatible with standard EEPROM and flash timing protocols
• Elimination of write delays associated with traditional non-volatile memory technologies

Memory IC Applications

• Industrial automation systems requiring high endurance logging
• Automotive electronics applications demanding reliability
• Data acquisition systems needing rapid write cycles

Memory IC Procurement Notes

Verify the specific suffix 'A' against the official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the DFN-8 package dimensions align with your PCB footprint constraints. Confirm that the SPI interface timing parameters are compatible with your host controller before finalizing procurement.

Memory IC Selection Notes

Select this component when designing systems that require unlimited write endurance and fast write speeds without the latency typical of flash memory. It serves as a drop-in replacement for serial EEPROMs and flash devices where power-down data retention is critical. Consider the 3.3V operating voltage and SPI compatibility when evaluating system power budgets and microcontroller interfaces.

Memory IC Part Context

This part belongs to the MR25Hxx series of serial SPI MRAM devices from Everspin Technologies. This family combines the speed and endurance of RAM with the non-volatility of flash, offering a robust solution for embedded storage applications that demand frequent data updates and long-term reliability.

Memory IC Replacement Considerations

Consult the official Everspin documentation for verified cross-reference part numbers. Do not assume functional equivalence with generic SPI flash or EEPROM parts without verifying voltage levels, command sets, and physical package dimensions.
