MR1A16AMYS35

Memory IC Overview

The MR1A16AMYS35 is a 2 Mbit Magnetoresistive Random Access Memory (MRAM) device manufactured by Everspin Technologies. It features a parallel interface with a 16-bit data bus width and an organization of 128 k x 16. The component operates within a supply voltage range of 3 V to 3.6 V and supports a maximum access time of 35 ns. It is housed in a TSOP-II-44 package suitable for surface mount technology. The industrial temperature grade ensures reliable operation across a wide range from -40°C to +125°C, with a power dissipation rating of 600 mW.

Memory IC Feature Summary

• Non-volatile memory architecture providing unlimited read/write endurance without the wear-out limitations associated with flash technology.
• Parallel I/O interface supporting high-speed data transfer with a 16-bit bus width and 35 ns access time.
• Industrial temperature rating enabling stable performance in extreme environments ranging from -40°C to +125°C.

Memory IC Applications

• Data logging systems requiring frequent write cycles and long-term data retention.
• Industrial control units operating in high-temperature or harsh environmental conditions.
• Embedded systems needing non-volatile storage with high endurance and fast random access.

Memory IC Procurement Notes

Verify the specific suffix 'M' indicates the industrial temperature grade (-40°C to +125°C) compared to commercial variants. Confirm the TSOP-II-44 package dimensions match your PCB footprint requirements. Ensure the parallel interface signals are correctly routed for the 16-bit data bus. Check RoHS compliance documentation for regulatory adherence. Validate that the 3V to 3.6V supply voltage aligns with your system's power design.

Memory IC Selection Notes

Select this part when high endurance and non-volatility are critical, replacing traditional Flash or EEPROM solutions. The 16-bit parallel interface offers faster throughput than serial alternatives. The industrial temperature range makes it suitable for demanding applications where commercial grade parts would fail. Consider the 600 mW power dissipation for thermal management in enclosed designs.

Memory IC Part Context

This component belongs to the MR1A16A series of parallel MRAM devices from Everspin Technologies. It shares the same core memory architecture and interface specifications as other variants in the family, differing primarily in temperature ratings and packaging options. The series is designed for applications requiring robust, high-endurance non-volatile storage with fast access times.

Memory IC Replacement Considerations

The MR1A16ACYS35R serves as a commercial grade alternative with a restricted temperature range of 0°C to +85°C. Verify that the lower temperature limit does not compromise system reliability in cold environments. Electrical parameters remain identical, ensuring pin-to-pin compatibility.
