MR25H128ACDF

Memory IC Overview

The MR25H128ACDF is a magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It features a storage capacity of 128 kbit organized as 16k x 8 with an 8-bit data bus width. The component operates on a serial peripheral interface (SPI) and accepts a supply voltage between 2.7 V and 3.6 V. Power consumption specifications list operating currents at 6 mA and 23 mA, with a maximum power dissipation of 600 mW. The device is housed in an 8-lead DFN package designed for surface mount technology and supports an industrial temperature range from -40 C to +85 C.

Memory IC Feature Summary

• Provides non-volatile data retention without requiring write delays or erase cycles, functioning similarly to serial EEPROMs and flash.

Memory IC Applications

• Data logging systems
• Parameter storage for electric powertrains

Memory IC Procurement Notes

Verify the specific suffix 'CDF' against the manufacturer's current datasheet to confirm the tray packaging configuration and lead-free status. Ensure design compatibility with the 8-pin DFN footprint and exposed pad thermal requirements. Confirm that the SPI timing parameters align with the host controller's maximum clock speed capabilities before finalizing procurement.

Memory IC Selection Notes

Select this component when high endurance and instant write completion are required compared to traditional flash memory. The 128 kbit density suits applications needing moderate storage for configuration data. Verify that the 3.3V nominal supply range fits the system power architecture. Consider the DFN-8 package size constraints during PCB layout planning.

Memory IC Part Context

This part belongs to the MR25H128A series of serial SPI MRAM devices. These components utilize spin-transfer torque technology to offer unlimited read/write endurance. The series is designed to replace legacy EEPROM and Flash memories in applications demanding high reliability and fast write speeds.

Memory IC Replacement Considerations

Check for MR25H128ACDFR if reel packaging is preferred over trays. Verify MR25H256ACDF for double capacity options within the same package family.
