MR2A16AYS35

Memory IC Overview

The MR2A16AYS35 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 16-bit data bus width. 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 fast access time of 35 ns and supports an operating temperature range from 0°C to +70°C. The memory is housed in a TSOP-II-44 surface-mount package.

Memory IC Feature Summary

• Provides non-volatile data retention exceeding 20 years without requiring power.
• Delivers unlimited read and write endurance, eliminating wear-out limitations found in flash technologies.
• Maintains SRAM-compatible timing characteristics for seamless integration into existing designs.

Memory IC Applications

• Replacing battery-backed SRAM solutions to improve system reliability.
• Simplifying embedded design by consolidating Flash, SRAM, and EEPROM functions.
• Supporting industrial control systems requiring high-speed data logging.

Memory IC Procurement Notes

Verify the specific suffix 'YS' against the manufacturer's official documentation to confirm the exact commercial temperature grade and package variant. Ensure that the required moisture sensitivity level and reflow soldering profiles align with your assembly capabilities. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Memory IC Selection Notes

Select this component when a design requires the speed of SRAM combined with the non-volatility of Flash. It is suitable for applications needing frequent data updates without endurance concerns. Consider the TSOP-II-44 footprint constraints and verify that the 3.3V logic levels match the host processor interface requirements.

Memory IC Part Context

This part belongs to the MR2A16A series of parallel MRAM devices. It represents a class of spin-transfer torque magnetic memory designed to bridge the gap between volatile high-speed memory and non-volatile storage. The series focuses on providing robust data retention and high cycle life for critical embedded applications.

Memory IC Replacement Considerations

Direct substitutes include other parts within the MR2A16A family, such as the MR2A16ACMA35, which shares identical electrical specifications but utilizes a BGA-48 package instead of TSOP-II-44. Verify pinout compatibility before swapping packages.
