EM004LXOBB320ES2T

Memory IC Overview

The EM004LXOBB320ES2T is a 4 Mbit Magnetoresistive Random Access Memory (MRAM) device manufactured by Everspin Technologies. It features an Octal SPI interface operating at frequencies up to 200 MHz, delivering high-speed data transfer capabilities. The memory is organized as 4 M x 8 bits and operates within a supply voltage range of 1.65 V to 2 V. The component is housed in a 24-ball Thin Ball Grid Array (TBGA) package measuring 6x8 mm. It supports industrial temperature ranges from -40°C to +105°C and includes humidity sensitivity classification.

Memory IC Feature Summary

• Provides non-volatile storage with unlimited read/write endurance characteristics typical of spin-transfer torque MRAM technology.
• Supports high-performance data throughput via eight simultaneous input/output signals compatible with standard SPI protocols.
• Operates on a single low-voltage power supply suitable for energy-efficient embedded systems.

Memory IC Applications

• Industrial automation control systems requiring persistent configuration storage
• Automotive electronics needing reliable data retention under varying thermal conditions
• Embedded systems utilizing SPI-compatible interfaces for firmware or parameter logging

Memory IC Procurement Notes

Verify the specific suffix ES2T against official Everspin documentation to confirm package type and temperature grade. Ensure compatibility with 1.65V to 2V logic levels in the target design. Check for moisture sensitivity level requirements during assembly. Confirm that the 24-TBGA footprint matches the PCB layout specifications exactly before ordering.

Memory IC Selection Notes

Select this component when non-volatility combined with SRAM-like speed and infinite endurance is required. The Octal SPI interface offers higher bandwidth than traditional quad-SPI devices. Consider the 24-TBGA package constraints for board space. Verify that the 4Mbit capacity meets system memory needs without excessive overhead compared to larger density options.

Memory IC Part Context

This part belongs to the EMxxLX family of high-density STT-MRAM devices from Everspin Technologies. The family is designed for applications demanding high performance and reliability. These devices bridge the gap between volatile RAM and traditional non-volatile memories like Flash. The EM004LXO variant specifically targets smaller capacity requirements within this high-speed serial interface category.

Memory IC Replacement Considerations

Direct substitutes are limited due to proprietary MRAM architecture. Review Everspin's internal cross-reference guides for equivalent density and interface types. No generic industry-standard replacements exist for this specific combination of Octal SPI and MRAM technology. Validate pinout and electrical parameters if considering alternative vendors.
