EM004LXQBB313IS1R

Memory IC Overview

The EM004LXQBB313IS1R is a 4 Mbit Magnetoresistive Random Access Memory (MRAM) device manufactured by Everspin Technologies. It features a Quad SPI interface operating at frequencies up to 133 MHz. The memory is organized as 512 k x 8 bits and is housed in a 24-BGA package. The device operates within a supply voltage range of 1.65 V to 2 V and supports an industrial temperature range from 0°C to +70°C.

Memory IC Feature Summary

• Provides non-volatile data retention without requiring power for storage
• Supports high-speed serial communication via Quad SPI protocol
• Enables unlimited write endurance characteristics typical of MRAM technology

Memory IC Applications

• Industrial control systems requiring persistent configuration storage
• Data logging applications needing frequent write cycles
• Embedded systems utilizing code-in-place execution

Memory IC Procurement Notes

Verify the specific suffix 'IS1R' against official Everspin documentation to confirm temperature grade and packaging details. Ensure compatibility with host controller SPI modes supporting quad I/O operations. Confirm that the 24-BGA footprint matches the target PCB design constraints before procurement.

Memory IC Selection Notes

Select this component when non-volatility and high endurance are critical requirements. The Quad SPI interface offers higher throughput compared to standard SPI variants. Verify that the system power supply remains stable within the 1.65 V to 2 V operational window to ensure reliable data integrity during read and write operations.

Memory IC Part Context

This part belongs to the Everspin EMxxLX family of unified code and data memory devices. These MRAM products combine the speed of SRAM with the persistence of flash, targeting applications where traditional memory technologies face endurance or latency limitations. The family emphasizes low voltage operation and compact packaging solutions.

Memory IC Replacement Considerations

Consult official Everspin substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications carefully when considering generic MRAM replacements to ensure functional compatibility.
