MR1A16AYS35R

Memory IC Overview

The MR1A16AYS35R is a 2 Mbit Magnetoresistive Random Access Memory (MRAM) device manufactured by Everspin Technologies. It features a parallel interface with a data bus width of 16 bits and an organization of 128 k x 16. The component operates within a supply voltage range of 3 V to 3.6 V, with access times of 35 ns. Power consumption specifications indicate operating currents of 55 mA and 105 mA, with a maximum power dissipation of 600 mW. It is housed in a TSOP-II-44 package designed for surface mount technology and supports an industrial temperature range from 0°C to +70°C.

Memory IC Feature Summary

• Non-volatile memory architecture retains data without continuous power supply.
• Parallel I/O interface enables direct connection to standard logic systems.
• Surface-mount TSOP-II-44 packaging facilitates automated PCB assembly.

Memory IC Applications

• Industrial control systems requiring persistent data storage
• Embedded applications needing fast random access capabilities
• Automotive electronics operating within specified temperature limits

Memory IC Procurement Notes

Verify the specific suffix 'S' confirms the commercial temperature grade (0°C to +70°C) against the official datasheet, as other suffixes may denote extended ranges. Confirm the TSOP-II-44 package dimensions match your footprint requirements. Ensure the 3.3V nominal supply aligns with your system's voltage rails. Check for RoHS compliance status if required by your manufacturing standards.

Memory IC Selection Notes

Select this part when a 2 Mbit capacity with 16-bit word width is required. Compare against the MR1A16AMYS35R if an extended industrial temperature range (-40°C to +125°C) is necessary instead of the commercial grade. Consider the MR0A16AYS35R if only 1 Mbit capacity suffices. Verify that the parallel interface fits your controller's available pins compared to serial alternatives.

Memory IC Part Context

This component belongs to the MR1A16A series of parallel MRAM devices from Everspin Technologies. It shares the same physical package and interface characteristics as other variants in the family but differs in temperature rating and specific organizational parameters. It serves as a non-volatile alternative to traditional SRAM or Flash solutions in embedded memory applications.

Memory IC Replacement Considerations

The MR1A16AMYS35R is a verified substitute offering identical electrical and pinout specifications but with an extended industrial temperature range (-40°C to +125°C). Ensure the application environment does not exceed the original component's commercial limits before substituting.
