MR5A16AUYS45R

Memory IC Overview

The MR5A16AUYS45R 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. The device supports surface mount installation in a TSOP-II-54 package and functions across an industrial temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Provides non-volatile data retention without requiring power for storage maintenance.
• Delivers SRAM-compatible read/write timing characteristics for direct replacement applications.
• Supports unlimited write endurance cycles compared to traditional flash memory technologies.

Memory IC Applications

• Industrial control systems requiring high reliability
• Automotive electronics operating in extreme temperatures
• Embedded systems needing fast random access memory

Memory IC Procurement Notes

Verify the specific suffix codes against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for TSOP-II-54 packages. Confirm humidity sensitivity levels and reflow soldering profiles prior to assembly. Validate that the parallel interface signals match the host controller requirements.

Memory IC Selection Notes

Select this part when non-volatility and unlimited endurance are critical alongside SRAM-like speed. The 32 Mbit capacity suits applications needing substantial persistent storage. Consider the TSOP-II-54 package for standard surface mount processes. Verify thermal management capabilities for operation up to +125°C ambient conditions.

Memory IC Part Context

This component belongs to the MR5A16A series of parallel MRAM devices. It shares architectural similarities with other parts in the family but differs in specific packaging and performance parameters. The series is designed to replace volatile SRAM or non-volatile flash in various embedded environments.

Memory IC Replacement Considerations

Direct substitutes include MR4A16BUYS45R for lower density needs. Cross-reference pinouts and electrical specifications carefully before substitution. Verify that alternative components meet the same temperature and voltage requirements.
