EM004LXOBB320IS1R

Memory IC Overview

The EM004LXOBB320IS1R is a 4 Mbit Magnetoresistive Random Access Memory (MRAM) integrated circuit manufactured by Everspin Technologies. It features an Octal SPI interface and is organized as 512 k x 8 bits. The device operates within a supply voltage range of 1.65 V to 2 V. It supports high-speed data transfer rates up to 200 MHz. The component is housed in a 24-ball Ball Grid Array (BGA) package designed for surface mount technology. It functions reliably across an industrial temperature range from -40°C to +105°C.

Memory IC Feature Summary

• Non-volatile memory architecture retains data without power
• Octal Serial Peripheral Interface enables high-bandwidth communication
• Industrial-grade thermal stability for demanding environments

Memory IC Applications

• Embedded systems requiring persistent storage
• Industrial control units needing fast write endurance
• Automotive electronics with strict reliability standards

Memory IC Procurement Notes

Verify the specific suffix 'IS1R' against official Everspin documentation to confirm temperature grade and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 24-BGA package. Confirm that the target system supports the required 1.65 V to 2 V operating voltage range before integration.

Memory IC Selection Notes

Select this component when non-volatility and high write endurance are critical compared to traditional flash memory. The Octal SPI interface offers superior throughput over standard SPI variants. Consider the BGA-24 footprint constraints and the need for precise voltage regulation within the 1.65 V to 2 V window during design.

Memory IC Part Context

This part belongs to the Everspin MRAM family, which utilizes spin-transfer torque technology. It serves as a drop-in replacement for SRAM in many applications due to its non-volatile nature. The series is designed to bridge the gap between volatile memory speed and non-volatile storage retention.

Memory IC Replacement Considerations

EM004LXOBB320ES2R is listed as a suggested alternate part number. Verify pinout and electrical parameter equivalence before substitution.
