MR4A08BCMA35

Memory IC Overview

The MR4A08BCMA35 is a 16 Mbit Magnetoresistive Random Access Memory (MRAM) device manufactured by Everspin Technologies. It features a parallel interface with an organization of 2 M x 8 and an 8-bit data bus width. The component provides a fast access time of 35 ns, ensuring SRAM-compatible timing performance. It operates within a supply voltage range of 3 V to 3.6 V and supports an industrial temperature range from -40°C to +85°C. The memory is housed in a BGA-48 package.

Memory IC Feature Summary

• Provides unlimited read and write endurance for high-cycle applications
• Maintains data non-volatility for over 20 years without power
• Includes internal single bit error correction code with parity bits

Memory IC Applications

• Industrial control systems requiring persistent data storage
• Automotive electronics demanding high reliability
• Embedded systems needing SRAM-compatible speed with non-volatile retention

Memory IC Procurement Notes

Verify the specific suffix 'R' against the requested part number. The provided model lacks the trailing character found in common distributor listings. Confirm package type and moisture sensitivity level requirements with the supplier before ordering to ensure compatibility with assembly processes.

Memory IC Selection Notes

Select this component when designing systems that require frequent data logging or configuration changes without wear-out concerns. The parallel interface suits applications where pin count allows for wider buses compared to serial alternatives. Ensure the PCB layout accommodates the BGA-48 footprint and thermal dissipation needs.

Memory IC Part Context

This device belongs to the MR4A08B series of parallel MRAMs. It shares core technology with the MR4A16B but differs in memory organization and data bus width. The series is designed to replace traditional SRAM and Flash combinations in space-constrained embedded designs.

Memory IC Replacement Considerations

Direct functional substitutes include the MR4A08BCYS35 in TSOP-II packaging. Verify pinout compatibility and voltage levels when cross-referencing with other MRAM families.
