MR2A08ACYS35

Memory IC Overview

The MR2A08ACYS35 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 bits 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 supply voltage range of 3 V to 3.6 V. The device is housed in a TSOP-II-44 package and supports surface mount installation. It is designed for commercial temperature ranges, operating between 0°C and +70°C.

Memory IC Feature Summary

• Provides SRAM-compatible timing to allow integration with existing controllers without redesign
• Ensures data non-volatility for over 20 years without requiring power
• Supports unlimited read and write endurance cycles

Memory IC Applications

• Replacing battery-backed SRAM solutions to improve system reliability
• Simplifying design by consolidating Flash, SRAM, EEPROM, and BBSRAM functions into one memory component
• Embedded systems requiring high-speed non-volatile data retention

Memory IC Procurement Notes

Verify the specific suffix 'YS' against official datasheets to confirm package type and temperature grade alignment. Ensure the ordering quantity matches the manufacturer's minimum order requirements and packaging constraints. Confirm RoHS compliance status through the latest documentation before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when SRAM-like speed is required alongside permanent data retention. It serves as a direct drop-in replacement for volatile SRAM in applications where power loss must not result in data loss. Consider the TSOP-II-44 footprint and 3.3V logic levels during PCB layout and system architecture planning.

Memory IC Part Context

This part belongs to the MR2A08A series of parallel I/O MRAM devices from Everspin Technologies. The series is characterized by its ability to replace multiple memory types in a single chip, offering high density and endurance. It is distinct from other series like MR4 or MR5 which may offer different capacities or toggle interfaces.

Memory IC Replacement Considerations

Direct pin-to-pin replacements include MR2A08ACMA35 for BGA packaging variants. Verify electrical compatibility and thermal specifications when substituting with other MRAM models from the same manufacturer.
