MR4A16BUYS45

Memory IC Overview

The MR4A16BUYS45 is a magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It features a storage capacity of 16 Mbit organized as 1M x 16 bits with a parallel interface. The component operates within a voltage range of 3 V to 3.6 V and supports an access time of 45 ns. It functions in temperatures from -40 C to +125 C, housed in a TSOP-II-54 package.

Memory IC Feature Summary

• Provides SRAM-compatible timing for seamless integration into existing designs.
• Offers unlimited read and write endurance without degradation over time.
• Maintains data non-volatility for extended periods at specified operating temperatures.

Memory IC Applications

• Industrial control systems requiring reliable data retention
• Automotive electronics operating in high-temperature environments
• Embedded solutions needing persistent memory storage

Memory IC Procurement Notes

Verify the specific suffix 'S45' against official Everspin documentation to confirm the exact package type and temperature grade. Ensure compatibility with system voltage requirements ranging from 3 V to 3.6 V. Confirm that the 45 ns access time meets the target application's performance specifications before finalizing procurement.

Memory IC Selection Notes

Select this part when SRAM-like speed is required alongside non-volatile data retention. The 1M x 16 organization suits applications needing wide data buses. Consider the TSOP-II-54 package for surface-mount assembly constraints. Verify thermal management capabilities for operation up to +125 C.

Memory IC Part Context

This component belongs to the MR4A16B series of parallel MRAM devices. It shares architectural similarities with other members like the MR4A08B but offers higher density through its 16-bit width configuration. The series is designed for robust performance in demanding industrial and automotive sectors.

Memory IC Replacement Considerations

Check for direct substitutes within the MR4A16B family, such as variants with different access times or packages. Ensure any replacement maintains the 1M x 16 organization and parallel interface compatibility.
