MR3A16ACYS35

Memory IC Overview

The MR3A16ACYS35 is an 8 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 512 k x 16. The access time is 35 ns, operating within a supply voltage range of 3 V to 3.6 V. Power consumption varies between 60 mA and 152 mA depending on the operational state. The component supports surface mount installation in a 54-TSOP-II package and functions reliably across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Provides non-volatile data retention exceeding 20 years without requiring periodic refreshing or battery backup.
• Offers unlimited read and write endurance, eliminating wear-out limitations associated with traditional flash memory technologies.
• Maintains SRAM-compatible timing characteristics, allowing integration into existing systems without controller redesign.

Memory IC Applications

• Industrial control systems requiring persistent parameter storage
• Automotive electronics demanding high reliability and vibration resistance
• Smart devices needing fast data caching and retrieval

Memory IC Procurement Notes

Verify the specific suffix 'YS35' against the official datasheet to confirm the package type, temperature grade, and moisture sensitivity level. Ensure that the parallel interface requirements match the target system's bus architecture. Confirm RoHS compliance status for environmental regulations. Check for any recent product change notices affecting pinout or electrical specifications before finalizing procurement.

Memory IC Selection Notes

Select this component when a system requires non-volatile memory with infinite endurance and SRAM-like speed. It serves as a direct replacement for battery-backed SRAM, EEPROM, and Flash in applications where power loss protection is critical. Consider the 54-pin TSOP-II footprint for PCB layout constraints. Evaluate the 3.3V supply requirement against available power rails.

Memory IC Part Context

This part belongs to the MR3A16A series of asynchronous MRAM devices from Everspin Technologies. The series utilizes spin-transfer torque magnetoresistive technology to combine the density of non-volatile memory with the speed and endurance of volatile RAM. These devices are designed to replace multiple memory types in a single chip, simplifying system design and reducing component count.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with legacy SRAM or Flash solutions based on pinout and timing parameters rather than assuming direct interchangeability.
