MR256D08BMA45

Memory IC Overview

The MR256D08BMA45 is a Magnetoresistive Random Access Memory (MRAM) device manufactured by Everspin Technologies. It features a storage capacity of 256 kbit, organized as 32k x 8 words with an 8-bit data bus width. The component utilizes a parallel interface and offers a typical access time of 45 ns. It operates within a supply voltage range of 3 V to 3.6 V. The device is housed in a BGA-48 package and supports surface mount installation. It is rated for commercial temperature operation between 0°C and +70°C.

Memory IC Feature Summary

• Non-volatile memory technology providing unlimited write endurance without the wear-out limitations associated with flash or EEPROM technologies.
• Parallel I/O interface compatible with standard SRAM timing requirements for direct replacement in legacy designs.
• Robust construction suitable for industrial environments with specified operating temperature ranges.

Memory IC Applications

• Industrial control systems requiring high reliability and frequent data logging.
• Automotive electronics where non-vatility and endurance are critical.
• Embedded systems needing fast random access memory with long-term data retention.

Memory IC Procurement Notes

Verify current availability status as this specific part number may be subject to discontinuation notices. Confirm that the BGA-48 package footprint matches your PCB design constraints. Ensure that the 3V to 3.6V supply voltage aligns with your system power rails. Check for any moisture sensitivity level requirements during assembly processing. Validate that the 45 ns access time meets your system's timing specifications.

Memory IC Selection Notes

Select this component when designing systems that require non-volatile memory with infinite endurance and SRAM-like speed. Consider the BGA-48 package size and thermal characteristics for your enclosure. Compare against other MRAM families if higher density or different interface types such as SPI or Toggle are required. Ensure the commercial temperature range of 0°C to +70°C is sufficient for your application environment.

Memory IC Part Context

This device belongs to the MR256D08B series of parallel MRAM products from Everspin Technologies. It represents a mid-density solution bridging smaller serial memories and larger parallel arrays. The series is designed to replace traditional volatile RAM with battery backup or non-volatile flash solutions in applications demanding high write cycles.
