MR2A16AMA35R

Memory IC Overview

The MR2A16AMA35R is a 4 Mbit Magnetoresistive Random Access Memory (MRAM) device manufactured by Everspin Technologies. It features a 256K x 16 organization with a parallel interface and a 35 ns access time. The component operates on a 3 V to 3.6 V power supply, drawing 55 mA typical and 105 mA maximum current. It supports an industrial temperature range of -40°C to +85°C and is housed in a TSOP-II-44 package.

Memory IC Feature Summary

• Non-volatile data retention without requiring battery backup or refresh cycles
• Indistinguishable read and write speeds for high-performance random access
• Unlimited endurance capability eliminating wear-out limitations

Memory IC Applications

• Industrial control systems requiring persistent parameter storage
• Automotive electronics demanding high reliability and wide temperature operation
• Smart devices needing rapid data caching and frequent write operations

Memory IC Procurement Notes

Verify the specific suffix 'R' indicates reel packaging versus tray options when sourcing. Confirm RoHS compliance status through official documentation. Ensure compatibility with 3.3V logic levels and check humidity sensitivity handling requirements during assembly. Validate lead times as production cycles may vary.

Memory IC Selection Notes

Select this part for applications requiring non-volatile memory with infinite write endurance. The 16-bit parallel interface suits high-throughput data logging. Consider the TSOP-II-44 footprint for PCB layout constraints. Compare against serial alternatives if pin count reduction is critical, noting the speed advantage of parallel I/O.

Memory IC Part Context

This component belongs to the MR2A16A series of asynchronous MRAM devices. It utilizes spin-transfer torque technology to provide fast, reliable storage. The series is designed to replace traditional SRAM and Flash solutions in embedded systems where data integrity and speed are paramount.

Memory IC Replacement Considerations

Direct substitutes include other MR2A16A variants with different packaging such as MR2A16ACMA35. Verify pinout compatibility before swapping between TSOP and BGA packages. Serial SPI versions like MR25Hxx offer similar functionality but with different timing characteristics.
