MR3A16AUYS45

Memory IC Overview

The MR3A16AUYS45 is a magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It features an 8 Mbit storage capacity organized as 512 k x 16 bits with a 16-bit data bus width. The component utilizes a parallel interface and offers a 45 ns access time. It operates within a supply voltage range of 3 V to 3.6 V, with working power currents specified at 60 mA and 152 mA. The device supports surface mount installation in a TSOP-II-54 package and functions reliably across an extended temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Provides non-volatile data retention exceeding 20 years without requiring power.
• Delivers SRAM-compatible read/write timing for seamless integration into existing designs.
• Supports unlimited read and write endurance cycles without degradation.

Memory IC Applications

• Industrial control systems requiring persistent data storage

Memory IC Procurement Notes

Verify the specific suffix codes against official datasheets to confirm package type and temperature grade compatibility. Ensure that the parallel interface requirements match the target system architecture before procurement. Confirm RoHS compliance status through manufacturer documentation. Validate that the 3V to 3.6V supply voltage aligns with the design's power rails. Check for any recent product change notices affecting pinout or electrical characteristics.

Memory IC Selection Notes

Select this component when non-volatility combined with high-speed parallel access is required. The 16-bit organization suits applications needing wide data paths. Consider the TSOP-II-54 package constraints for PCB layout. Evaluate the thermal performance given the +125°C maximum operating temperature rating. Compare power consumption figures against alternative memory technologies for efficiency analysis.
