MR5A16AUMA45

Memory IC Overview

The MR5A16AUMA45 is a magnetoresistive random-access memory (MRAM) integrated circuit manufactured by Everspin Technologies. It provides a storage capacity of 32 Mbit, organized as 2M x 16 words with a 16-bit data bus width. The device features a parallel interface and supports an access time of 45 ns. It operates within a supply voltage range of 3 V to 3.6 V and functions across an industrial temperature range from -40°C to +125°C. The component is housed in a 48-LFBGA package measuring 10x10 mm.

Memory IC Feature Summary

• Non-volatile magnetic storage technology providing unlimited read/write endurance without wear-out limitations.

Memory IC Applications

• Industrial control systems requiring high-temperature operation up to 125°C
• Automotive electronics applications certified under AEC-Q100 standards
• Embedded systems needing non-volatile data retention with SRAM-like speed

Memory IC Procurement Notes

Verify the specific suffix code against official documentation to confirm package type and operating temperature grade. Ensure compatibility with parallel interface requirements and voltage levels. Confirm moisture sensitivity level handling procedures during assembly. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

Memory IC Selection Notes

Select this component when non-volatility and infinite endurance are critical alongside fast parallel access speeds. The 45 ns access time suits applications demanding SRAM-equivalent performance. The wide temperature range makes it suitable for harsh environments. Consider the BGA footprint constraints and power dissipation limits relative to system design requirements.

Memory IC Part Context

This part belongs to the MR5A16A series of parallel MRAM devices. It shares core architectural features with other variants in the family but differs in packaging and timing specifications. The series is designed to replace traditional SRAM and Flash solutions in embedded memory applications requiring high reliability and durability.

Memory IC Replacement Considerations

Direct replacements include MR5A16AUMA35 for faster 35 ns access in the same package. For TSOP-II-54 packages, consider MR5A16AUYS45R. Verify pin compatibility and electrical parameters before substituting with older MR4 series parts.
