MR0A16AVYS35R

Memory IC Overview

The MR0A16AVYS35R is a 1 Mbit Magnetoresistive Random Access Memory (MRAM) device manufactured by Everspin Technologies. It features a 64 k x 16 organization with a 16-bit data bus width and parallel interface. The component operates within a supply voltage range of 3 V to 3.6 V, consuming 55 mA during active operation and 105 mA in standby mode. It offers a maximum access time of 35 ns and supports an industrial operating temperature range from -40 °C to +85 °C. The memory is housed in a TSOP-II-44 surface-mount package.

Memory IC Feature Summary

• Provides non-volatile data storage that retains information without power while enabling fast random access speeds comparable to SRAM.
• Eliminates the need for write cycles or refresh operations, offering infinite endurance against wear-out mechanisms common in flash memory.
• Maintains data integrity across extended industrial temperature ranges suitable for demanding environmental conditions.

Memory IC Applications

• Firmware boot code storage
• Embedded logging systems
• Industrial controller memory

Memory IC Procurement Notes

Verify the specific suffix 'AV' confirms the industrial temperature grade (-40°C to +85°C), as commercial variants exist. Confirm the 'R' suffix indicates reel packaging. Ensure compatibility with 3.3V logic levels and check for moisture sensitivity handling requirements prior to assembly.

Memory IC Selection Notes

Select this part when high-speed random access is required alongside non-volatility. It serves as a drop-in replacement for SRAM in applications needing persistent storage. Consider the 16-bit width for wider data paths and verify thermal management needs given the specified power dissipation limits.

Memory IC Part Context

This component belongs to the MR0A16A series of asynchronous MRAM devices. It utilizes magnetic tunnel junction technology to provide reliable data retention. The series is designed to bridge the performance gap between volatile RAM and slower non-volatile flash technologies.
