MR5A16AUMA45R

Memory IC Overview

The MR5A16AUMA45R is a magnetoresistive random-access memory (MRAM) device manufactured by Everspin Technologies. It features a storage capacity of 32 Mbit organized as 2 M x 16 with a 16-bit data bus width. The component utilizes a parallel interface and offers an access time of 45 ns. It operates within a supply voltage range of 3 V to 3.6 V, with power dissipation rated at 600 mW. The device supports surface-mount installation in a BGA-48 package and functions across a temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Provides non-volatile data retention with unlimited read/write endurance characteristics inherent to MRAM technology.
• Features a parallel I/O interface supporting high-speed data transfer with a 16-bit bus width.
• Designed for operation in extended industrial temperature environments up to +125°C.

Memory IC Applications

• Industrial control systems requiring high endurance memory
• Automotive electronics applications
• Embedded systems needing non-volatile storage

Memory IC Procurement Notes

Verify the specific suffix '45R' against official Everspin documentation to confirm the exact access speed and packaging configuration. Ensure compatibility with the required 3V to 3.6V supply rails and parallel interface signals. Confirm that the BGA-48 footprint matches the target PCB design constraints and thermal requirements for the intended operating environment.

Memory IC Selection Notes

Select this component when a parallel interface is required alongside high endurance and wide temperature tolerance. Compare the 45 ns access time against system timing requirements. Consider the BGA-48 package size relative to available board space. Evaluate the 32 Mbit capacity against total memory needs to ensure optimal utilization without excessive overhead.

Memory IC Part Context

This part belongs to the MR5A16A series of parallel MRAM devices from Everspin Technologies. The series includes variants with different access times and packages, such as the 35 ns and 45 ns versions. The MR5A16AUMA45R specifically denotes the 45 ns speed grade in a BGA-48 package, distinguishing it from TSOP-II options or faster BGA variants within the same family.

Memory IC Replacement Considerations

Check for other MR5A16AUMA variants with different speed grades if timing allows. Verify cross-references with other parallel MRAM parts only if they match the 32 Mbit capacity and 16-bit width exactly.
