MR0A16AYS35

Memory IC Overview

The MR0A16AYS35 is a magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It features a storage capacity of 1 Mbit organized as 64K x 16 with a 16-bit data bus width. The component utilizes a parallel interface and offers an access time of 35 ns. It operates within a supply voltage range of 3 V to 3.6 V, with working power currents specified at 55 mA and 105 mA. The device is housed in a TSOP-II-44 package suitable for surface mount technology. It supports an operating temperature range from 0 C to +70 C and has a maximum power dissipation of 600 mW.

Memory IC Feature Summary

• Utilizes spin-transfer torque MRAM technology for non-volatile data retention without requiring battery backup.
• Provides infinite read/write endurance, eliminating wear-out limitations associated with traditional flash memory technologies.
• Features parallel I/O interface architecture designed for high-speed data retrieval and low-latency system integration.

Memory IC Applications

• Industrial control systems requiring persistent parameter storage
• Automotive electronics demanding high reliability and vibration resistance
• Smart devices needing frequent data logging and rapid cache updates

Memory IC Procurement Notes

Verify the specific suffix codes against the official datasheet to ensure correct voltage and temperature ratings. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Check for any recent product change notices regarding assembly subcontractors or trace code formats. Ensure compatibility with existing PCB footprints for the TSOP-II-44 package.

Memory IC Selection Notes

Select this component when a 1 Mbit capacity with a 16-bit wide data path is required. The 35 ns access time suits applications needing faster response than serial interfaces. Verify that the 3.3 V nominal supply voltage aligns with the target system's power rails. Consider the TSOP-II-44 form factor for space-constrained surface mount designs.

Memory IC Part Context

This part belongs to the MR0A16A series of parallel MRAM devices from Everspin Technologies. It shares the TSOP-II-44 package and 35 ns speed class with other members like the MR2A08AYS35 and MR4A08BYS35, differing primarily in organization and bit-width configurations.

Memory IC Replacement Considerations

Direct substitutes include MR0A16AYS35T and MR0A16AYS35TR, which share identical electrical specifications but differ in reel packaging quantities. Verify pinout compatibility before swapping with older revisions.
