MR2A16AMYS35

Memory IC Overview

The MR2A16AMYS35 is a 4Mb (256K x 16) Magnetoresistive Random Access Memory (MRAM) device manufactured by Everspin Technologies. It features a parallel interface with a 35 ns access time and operates on a 3.0 V to 3.6 V power supply. The component is housed in a 48-ball BGA package and supports industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include a maximum power dissipation of 600 mW and compliance with MSL-3 moisture sensitivity levels.

Memory IC Feature Summary

• Provides unlimited read and write endurance, eliminating wear-out limitations found in traditional flash memory.
• Retains data non-volatile for over 20 years without requiring battery backup circuits.
• Offers SRAM-compatible timing to allow integration into existing designs without controller redesign.
• Includes automatic data protection mechanisms that activate during power loss events.

Memory IC Applications

• Industrial control systems requiring persistent parameter storage
• Automotive electronics meeting AEC-Q100 Grade 1 standards
