MR4A08BUYS45

Memory IC Overview

The MR4A08BUYS45 is a 16 Mbit magnetoresistive random access memory (MRAM) device organized as 2M x 8 bits. It features parallel interface with 35 ns read/write cycle time and operates on a 3.3 V power supply. The component is housed in a 44-lead TSOP2 package and supports an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Provides SRAM-compatible timing for seamless integration into existing designs.
• Offers unlimited read and write endurance without degradation over time.
• Ensures data retention for more than 20 years at elevated temperatures.

Memory IC Applications

• Industrial instrumentation requiring persistent data storage
• Automotive systems needing high reliability
• Embedded control applications

Memory IC Procurement Notes

Verify the specific suffix 'UYS45' against official Everspin documentation to confirm the exact package type, temperature grade, and moisture sensitivity level. Ensure compatibility with system voltage requirements and interface signals before procurement.

Memory IC Selection Notes

Select this part when non-volatile memory with infinite endurance is required. It serves as a drop-in replacement for volatile SRAM in systems needing fast access times and data persistence without battery backup.

Memory IC Part Context

This device belongs to the MR4A08B series of parallel MRAMs from Everspin Technologies. It utilizes spin-transfer torque technology to provide high-speed, non-volatile storage suitable for demanding embedded environments.

Memory IC Replacement Considerations

Direct substitutes include other MR4A08B variants with different packages or temperature ranges, such as MR4A08BCYS35 or MR4A08BMA35R, provided interface and form factor compatibility are verified.
