EM004LXQBDH13CS1R

Memory IC Overview

The EM004LXQBDH13CS1R is a 4 Mbit Magnetoresistive Random Access Memory (MRAM) integrated circuit manufactured by Everspin Technologies. It features a Quad SPI interface operating at frequencies up to 133 MHz. The device is organized as 512 k x 8 bits and operates within a supply voltage range of 1.65 V to 2 V. It is housed in an 8-DFN surface-mount package and supports industrial temperature ranges from 0°C to +70°C.

Memory IC Feature Summary

• Non-volatile memory technology providing instant-on capability without power loss retention
• Quad Serial Peripheral Interface (SPI) for high-speed data communication
• Low voltage operation compatible with 1.65 V to 2 V power supplies

Memory IC Applications

• Industrial control systems requiring persistent data storage
• Consumer electronics needing fast boot-up times
• Automotive applications utilizing MRAM durability

Memory IC Procurement Notes

Verify the specific suffix 'S1R' against official Everspin documentation to confirm tape and reel packaging specifications. Ensure compatibility with 1.65V to 2V logic levels before integration. Confirm RoHS compliance status through the manufacturer's current datasheet, as regulatory updates may affect ordering codes.

Memory IC Selection Notes

Select this component when non-volatility and high endurance are required alongside low power consumption. The 8-DFN package suits space-constrained designs. Verify that the 133 MHz Quad SPI speed meets system timing requirements. Consider thermal management within the 0°C to +70°C operational range for environmental stability.

Memory IC Part Context

This part belongs to the Everspin EMxxLX series of MRAM devices. These components utilize spin-transfer torque magnetic tunnel junctions to store data. The series offers infinite read/write endurance compared to flash memory alternatives. The Quad SPI variant provides enhanced throughput over standard SPI interfaces.

Memory IC Replacement Considerations

EM004LXQBDH13CS2R is listed as a suggested alternate part number by distributors. Verify pinout and electrical parameter equivalence with official Everspin substitution guides before implementation.
