MR25H10CDFR

Memory IC Overview

The MR25H10CDFR is a magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It offers a storage capacity of 1 Mbit, organized as 128 k 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-lead DFN package designed for surface mount technology. The device supports an operating temperature range from -40°C to +85°C and has a maximum power dissipation of 600 mW.

Memory IC Feature Summary

• Provides unlimited read/write endurance without write delays, functioning as a direct replacement for serial EEPROM and Flash memories.
• Features automatic data protection mechanisms that preserve stored information during unexpected power loss events.
• Supports block write protection capabilities to secure specific memory regions against unauthorized modification.

Memory IC Applications

• Industrial control systems requiring high endurance and reliable data retention
• Embedded applications needing non-volatile storage with fast random access
• Equipment demanding protection of critical configuration data during power interruptions

Memory IC Procurement Notes

Verify the specific suffix 'CDFR' corresponds to the required tape and reel packaging format rather than cut tape or tube options. Confirm that the 8-pin DFN package dimensions align with the target PCB footprint design. Ensure the SPI interface timing parameters meet the system controller requirements. Check for any moisture sensitivity level restrictions during assembly processing.

Memory IC Selection Notes

Select this component when designing systems that require infinite write endurance compared to traditional flash technologies. It is suitable for applications where frequent data logging or parameter updates occur. Consider the 1 Mbit capacity and SPI interface compatibility with existing microcontrollers. Evaluate the industrial temperature range suitability for the intended operational environment.

Memory IC Part Context

This part belongs to the MR25H10 series of magnetoresistive RAM devices from Everspin Technologies. The series is characterized by its spin-transfer torque MRAM technology, which combines the speed of SRAM with the non-volatility of EEPROM. The MR25H10 series provides a robust solution for embedded memory needs in various electronic systems.

Memory IC Replacement Considerations

The MR25H10CDF is the same device in a different packaging option. Verify if the specific reel or cut-tape requirement necessitates the 'FR' suffix over other available package variants within the same electrical specification family.
