MR4A16BMA35R

Memory IC Overview

The MR4A16BMA35R is a 16 Mbit magnetoresistive random access memory (MRAM) device organized as 1M x 16. It features a parallel interface with a 16-bit data bus width and a 35 ns access time. The component operates within a supply voltage range of 3 V to 3.6 V, with power dissipation rated at 600 mW. It is housed in a BGA-48 package suitable for surface mount technology. The industrial temperature range spans from -40 C to +85 C.

Memory IC Feature Summary

• Provides SRAM-compatible read/write timing for simplified system integration
• Ensures data retention exceeding 20 years without power
• Includes internal single bit error correction code with parity bits

Memory IC Applications

• Fault-tolerant embedded systems requiring persistent storage
• Industrial control applications needing high endurance
• Critical data logging in non-volatile memory environments

Memory IC Procurement Notes

Verify the specific suffix 'R' indicates reel packaging versus tray options when sourcing. Confirm moisture sensitivity level compliance for assembly processes. Ensure the industrial temperature grade matches environmental requirements. Cross-reference the exact part number with manufacturer documentation to confirm availability status and lead times prior to ordering.

Memory IC Selection Notes

Select this model for designs requiring unlimited write endurance compared to flash-based alternatives. The 16-bit organization suits wide data path architectures. Consider the BGA-48 footprint constraints during PCB layout. Verify that the 3.3V nominal supply aligns with the system's power rails and noise margins.

Memory IC Part Context

This component belongs to the MR4A16B series of parallel MRAM devices from Everspin Technologies. It shares core specifications with variants like MR4A16BCMA35R but differs in packaging format. The series is designed to replace traditional SRAM or Flash in applications demanding speed, endurance, and non-volatility.

Memory IC Replacement Considerations

Direct substitutes include MR4A16BCMA35R for reel-packaged equivalents. Check MR4A16BMA35 for tray-packaged versions with potentially different temperature ranges. Verify pin compatibility and electrical characteristics before swapping.
