EM004LXOBB320ES1R

Memory IC Overview

The EM004LXOBB320ES1R is a 4 Mbit magnetic random-access memory (MRAM) integrated circuit manufactured by Everspin Technologies. It features an Octal SPI interface and operates within a voltage range of 1.65 V to 2 V. The device is organized as 512 k x 8 bits and supports clock frequencies up to 200 MHz. It is housed in a 24-ball BGA package designed for surface mount technology. The component functions reliably across an industrial temperature range from -40°C to +105°C, with specified operating power currents of 124 mA and 156 mA.

Memory IC Feature Summary

• Non-volatile data retention utilizing magnetic tunnel junction technology
• High-speed serial communication via Octal SPI interface
• Robust endurance characteristics suitable for frequent write cycles

Memory IC Applications

• Industrial control systems requiring persistent configuration storage
• Automotive electronics demanding high-temperature reliability
• Embedded systems needing fast boot-up times without initialization delays

Memory IC Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and temperature grade compatibility. Ensure that the ordering information matches the exact part number required for your design, as variations may exist within the product family. Cross-reference the datasheet revision date to guarantee access to the most current electrical specifications and mechanical drawings before finalizing procurement plans.

Memory IC Selection Notes

Select this component when non-volatility combined with high-speed serial access is critical. The 4 Mbit capacity suits applications requiring moderate data persistence without the latency associated with traditional flash memory. Consider the 24-BGA footprint for compact board designs. Validate that the system power supply remains stable within the 1.65 V to 2 V window to ensure correct operation and data integrity during read and write sequences.

Memory IC Part Context

This MRAM belongs to Everspin's Octal SPI series, which integrates magnetic memory cells with standard serial peripheral interface logic. Unlike volatile SRAM or slower NAND flash, it offers immediate data availability upon power-up. The EM004LXOBB320ES1R variant specifically targets cost-sensitive applications requiring reliable data retention in harsh environments, bridging the gap between high-speed volatility and dense storage solutions.
