MR2A16AVMA35

Memory IC Overview

The MR2A16AVMA35 is a 4Mb Magnetoresistive Random Access Memory (MRAM) device manufactured by Everspin Technologies. It features a parallel interface with a data organization of 256K x 16 bits and a 16-bit data bus width. The component operates within a supply voltage range of 3V to 3.6V, consuming 55mA or 105mA depending on the operational state. It supports a maximum access time of 35ns and functions across an industrial temperature range from -40°C to +85°C. The device is housed in a 48-ball BGA package designed for surface mount technology.

Memory IC Feature Summary

• Provides unlimited read and write endurance, eliminating wear-out limitations associated with traditional flash memory technologies.
• Retains stored data non-volatilely for over 20 years without requiring power or battery backup circuitry.
• Offers SRAM-compatible timing characteristics, allowing integration into existing systems without controller redesign.

Memory IC Applications

• Industrial control systems requiring high reliability and frequent parameter updates
• Automotive electronics demanding robust performance under extreme temperature variations
• Smart devices needing persistent storage for critical configuration data

Memory IC Procurement Notes

Verify the specific suffix 'V' against official Everspin documentation to confirm the exact temperature grade and commercial availability status. Ensure the 48-ball BGA package dimensions align with your PCB footprint requirements. Confirm RoHS compliance and moisture sensitivity level ratings prior to assembly planning.

Memory IC Selection Notes

Select this component when designing systems that require the durability of non-volatile memory combined with the speed of volatile RAM. It serves as a direct replacement for battery-backed SRAM solutions, simplifying board design by removing external power management components for data retention.

Memory IC Part Context

This part belongs to the MR2A16A series of parallel MRAM devices. These chips are engineered to replace multiple distinct memory types, including Flash, EEPROM, and standard SRAM, within a single integrated circuit. This consolidation reduces system complexity and improves overall efficiency in embedded applications.

Memory IC Replacement Considerations

Direct pin-to-pin replacements include other variants within the MR2A16A family, such as the MR2A16ACMA35, provided the temperature range specifications meet the application requirements.
