MR1A16ACYS35R

Memory IC Overview

The MR1A16ACYS35R is a magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It features a storage capacity of 2 Mbit, organized as 128 k x 16 bits 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 and supports surface mount installation in a TSOP-II-44 package. The device is rated for industrial operating temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Provides non-volatile data retention without requiring periodic refreshing or battery backup.
• Offers unlimited read and write endurance, eliminating wear-out limitations associated with flash memory.
• Maintains SRAM-compatible timing characteristics to facilitate integration with existing controllers.

Memory IC Applications

• Industrial control systems requiring persistent data storage
• Automotive electronics demanding high reliability and endurance
• Embedded systems needing fast, non-volatile configuration retention

Memory IC Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the 35 ns access speed variant matches system timing requirements. Ensure the TSOP-II-44 footprint aligns with the PCB layout. Validate that the 3V to 3.6V supply range is compatible with the target power domain. Check current specifications against thermal dissipation limits in the final assembly.

Memory IC Selection Notes

Select this part for applications requiring infinite endurance and instant data persistence. Compare the 128k x 16 organization against alternative densities if space is constrained. Consider the parallel interface complexity versus serial options if pin count is limited. Evaluate the 35 ns latency against processor clock speeds to ensure adequate performance margins.

Memory IC Part Context

This component belongs to the MR1A16A series of parallel MRAM devices from Everspin Technologies. It serves as a non-volatile alternative to traditional volatile RAM and flash memory combinations. The series is designed to simplify system architecture by removing the need for backup batteries or complex write-protect sequences found in other non-volatile technologies.

Memory IC Replacement Considerations

Direct replacements include other MR1A16A variants with different access speeds or temperature grades. Verify pin compatibility before substituting with older MR2A16A models. Ensure any substitute maintains the 16-bit data bus width and parallel interface protocol.
