MR2A16AMYS35R

Memory IC Overview

The MR2A16AMYS35R is a 4Mb Magnetoresistive Random Access Memory (MRAM) device from Everspin Technologies. It features a 256K x 16 memory organization with a parallel interface and a 35 ns access time. Operating on a 3.3V supply, it supports an industrial temperature range of -40°C to +85°C. The component is housed in a 44-pin TSOP-II package and meets RoHS compliance standards.

Memory IC Feature Summary

• Provides unlimited read and write endurance for high-cycle applications
• Retains data non-volatilely for over 20 years without power
• Compatible with standard SRAM timing and controllers
• Includes automatic data protection during power loss events

Memory IC Applications

• Industrial control systems requiring persistent parameter storage
• Automotive electronics meeting AEC-Q100 Grade 1 standards
• Data logging devices needing high reliability and speed
• Battery-backed RAM replacement solutions

Memory IC Procurement Notes

Verify the specific suffix 'M' indicates the industrial temperature grade (-40°C to +85°C). Confirm the package type is TSOP-II-44. Ensure compatibility with existing SRAM controllers due to similar timing characteristics. Check for moisture sensitivity level requirements during handling.

Memory IC Selection Notes

Select this part when replacing Flash or EEPROM to achieve higher write speeds and infinite endurance. Choose the industrial grade variant for environments exceeding commercial temperature limits. Ensure the system design accommodates the 3.3V power supply and parallel interface constraints.

Memory IC Part Context

This component belongs to the MR2A16A series of parallel MRAM chips. It combines the non-volatility of flash with the speed of SRAM. Everspin Technologies manufactures these using spin-transfer torque technology on CMOS processes, offering a robust alternative to traditional volatile and non-volatile memory types.

Memory IC Replacement Considerations

Direct substitutes include other MR2A16A series variants with compatible pinouts and electrical specifications. Verify that any replacement maintains the 35 ns access time and 3.3V operating voltage to ensure system stability.
