MR2A08ACMA35R

Memory IC Overview

The MR2A08ACMA35R is a 4 Mbit magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It is organized as 512K x 8 bits and features a parallel interface with an 8-bit data bus width. The component operates within a voltage range of 3 V to 3.6 V, drawing 30 mA during read operations and 90 mA during write operations. It achieves a maximum access time of 35 ns. The device is housed in a TSOP-II-44 package and supports commercial operating temperatures from 0°C to +70°C.

Memory IC Feature Summary

• Provides non-volatile data retention exceeding 20 years without power.
• Offers unlimited read and write endurance compared to traditional flash memory.
• Maintains SRAM-compatible timing for direct replacement in existing designs.

Memory IC Applications

• Industrial control systems requiring high durability
• Embedded systems needing fast non-volatile storage
• Smart devices utilizing standard parallel interfaces

Memory IC Procurement Notes

Verify the specific suffix 'CMA' against official Everspin documentation to confirm temperature grade and package variations. Ensure compatibility with 3.3V logic levels and parallel controller requirements before integration. Cross-reference datasheet revisions to confirm pinout consistency.

Memory IC Selection Notes

Select this part for applications demanding infinite endurance and instant data persistence. It serves as a drop-in replacement for battery-backed SRAM or slow flash memories. Verify that the system architecture supports parallel I/O and the 3.3V supply rail constraints defined in the electrical specifications.

Memory IC Part Context

Everspin Technologies specializes in spin-transfer torque MRAM solutions derived from Freescale Semiconductor heritage. The company focuses on non-volatile memory products that combine RAM speed with flash-like persistence. This component belongs to their parallel interface family designed for industrial and commercial embedded markets.

Memory IC Replacement Considerations

Check for suffix variations such as 'AYS' or 'AMA' which may indicate different temperature ranges or packaging options. Confirm that substitute parts maintain the same 512Kx8 organization and 35ns access time to ensure functional equivalence.
