MR2A08ACYS35R

Memory IC Overview

The MR2A08ACYS35R is a magnetoresistive random access memory (MRAM) device manufactured by Everspin Technologies. It features a storage capacity of 4 Mbit organized as 512K x 8 with an 8-bit data bus width. The component utilizes a parallel interface and offers a fast access time of 35 ns. It operates within a voltage range of 3 V to 3.6 V, consuming 30 mA during active operation and 90 mA in standby mode. The device is housed in a TSOP-II-44 package and supports commercial temperature ranges from 0°C to +70°C.

Memory IC Feature Summary

• Provides non-volatile data retention exceeding 20 years without power.
• Offers unlimited read and write endurance capabilities.
• Maintains SRAM-compatible timing for seamless integration.

Memory IC Applications

• Replacing battery-backed SRAM solutions
• Industrial instrumentation systems
• Embedded control applications

Memory IC Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing. Confirm the AC designation aligns with the required commercial temperature range of 0°C to +70°C. Ensure the TSOP-II-44 footprint matches the target PCB layout. Cross-reference the 35 ns access speed against system timing requirements. Validate RoHS compliance status through official manufacturer documentation prior to procurement.

Memory IC Selection Notes

Select this part for designs requiring high endurance and non-volatility without complex controllers. Compare the 512K x 8 organization against alternative densities if larger capacity is needed. Evaluate the 3.3 V supply requirement against available system rails. Consider the TSOP-II-44 package constraints for board space limitations. Assess the 35 ns latency against processor clock speeds.

Memory IC Part Context

This component belongs to the MR2A08A series of parallel I/O MRAM devices. It serves as a direct replacement for traditional volatile memory types in embedded systems. The technology combines the speed of SRAM with the persistence of flash memory. It eliminates the need for backup batteries typically associated with SRAM implementations.

Memory IC Replacement Considerations

Direct substitutes include other MR2A08A variants with different temperature grades or packages. Verify pin compatibility before swapping with similar density parts. Check datasheet revisions for any functional updates in newer manufacturing lots.
