MR25H256MDCR

Memory IC Overview

The MR25H256MDCR is a magnetoresistive random-access memory (MRAM) integrated circuit manufactured by Everspin Technologies. It provides a storage capacity of 256 kbit organized as 32k x 8 bits with an 8-bit data bus width. The device utilizes a Serial Peripheral Interface (SPI) for communication and supports clock frequencies up to 40 MHz. It operates within a supply voltage range of 2.7 V to 3.6 V, with power dissipation rated at 600 mW. The component is housed in an 8-DFN package measuring 5x6 mm and is designed for surface mount installation. It functions reliably across an operating temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Non-volatile magnetic storage technology ensures data retention without power.
• Serial SPI interface enables simplified connection to host microcontrollers.
• Automotive-grade qualification supports operation in demanding environments.

Memory IC Applications

• Automotive electronic systems requiring durable non-volatile memory
• Industrial control applications needing high-temperature reliability
• Embedded systems utilizing serial peripheral interface protocols

Memory IC Procurement Notes

Verify the specific suffix MDCR indicates tape and reel packaging, distinct from tray options. Confirm AEC-Q100 automotive qualification status if required for your application. Check current lifecycle status as this part may be designated as not recommended for new designs. Ensure compatibility with 2.7V to 3.6V supply rails and SPI timing requirements before integration.

Memory IC Selection Notes

Select this component when non-volatile storage with high endurance and wide temperature tolerance is necessary. Compare against other MRAM variants based on package type and lifecycle status. Consider the 256 kbit capacity and SPI speed for system performance needs. Verify that the 8-DFN footprint matches your PCB design constraints and thermal management strategy.

Memory IC Part Context

This device belongs to the MR25H256 series of magnetoresistive RAM products from Everspin Technologies. It shares core specifications with related models like the MR25H256AMDF but differs in packaging configuration. The series is characterized by its use of magnetic tunnel junctions for data storage, offering superior durability compared to traditional flash memory technologies in industrial and automotive sectors.

Memory IC Replacement Considerations

The MR25H256AMDF is identified as a similar alternative within the same manufacturer lineup. Verify pinout compatibility and packaging differences between the DFN-8 reel and tray options. Ensure the replacement meets the same automotive qualification and temperature range requirements for direct substitution.
