MR4A08BUYS45R

Memory IC Overview

The MR4A08BUYS45R is a 16 Mbit magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It features a parallel interface with a storage organization of 1M x 16 and an 8-bit data bus width. The component operates within a voltage range of 3 V to 3.6 V, supporting a maximum operating temperature of +125°C. Key electrical specifications include a 45 ns access time and power consumption metrics of 60 mA and 152 mA.

Memory IC Feature Summary

• Provides SRAM-compatible timing for seamless integration into existing designs.
• Offers unlimited read and write endurance for high-cycle applications.
• Ensures data retention for over 20 years without power supply.
• Includes low-voltage inhibit circuitry to protect data during power loss.

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Automotive electronics operating in high-temperature environments
• Network infrastructure equipment needing reliable program storage

Memory IC Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when sourcing. Confirm the 1M x 16 organization matches the target design requirements, as other variants in the series may differ. Ensure the supplier provides RoHS compliance documentation and moisture sensitivity level details prior to procurement.

Memory IC Selection Notes

Select this part for applications demanding high endurance and non-volatility without battery backup. Compare against SRAM alternatives where data retention is critical. Consider the 125°C operating limit for harsh environment deployments. Verify pin compatibility with the TSOP-II-54 footprint during PCB layout.

Memory IC Part Context

This component belongs to the MR4A08B series of parallel MRAM devices from Everspin Technologies. It shares core magnetic tunnel junction technology with siblings like the MR4A08BMA35R but differs in organization and package type. The series is designed to replace volatile memory solutions in embedded systems requiring persistent storage.

Memory IC Replacement Considerations

Direct substitutes include MR4A08BUYS45. Check pinout compatibility with standard TSOP-II packages before replacing legacy SRAMs.
