MX25V4035FM2I

Memory IC Overview

The Macronix MX25V4035FM2I is a Serial NOR Flash memory device with a storage capacity of 4 Mbit. It operates within a voltage range of 2.7 V to 3.6 V and supports an SPI interface with a maximum clock frequency of 108 MHz. The component features a SOP-8 package (150mil) and offers flexible data organization options including 1M x 4, 2M x 2, or 4M x 1 configurations. It is designed for industrial temperature ranges, functioning between -40°C and +85°C.

Memory IC Feature Summary

• Supports standard SPI protocol with high-speed synchronous data transfer capabilities up to specified limits.
• Provides non-volatile data retention suitable for code execution and general-purpose storage applications.
• Engineered for surface-mount technology integration using compact SOP-8 packaging.

Memory IC Applications

• Industrial control systems requiring reliable code storage
• Automotive electronics operating under extended temperature conditions
• Consumer devices utilizing serial flash for firmware retention

Memory IC Procurement Notes

Verify the specific suffix 'M2I' against official Macronix documentation to confirm package dimensions and thermal characteristics. Ensure compatibility with existing PCB footprints for SOP-8 150mil components. Confirm that the 2.7V minimum supply voltage aligns with system power rails. Validate that the 108 MHz clock speed meets design timing requirements. Check for moisture sensitivity levels if reflow soldering is planned.

Memory IC Selection Notes

Select this component when a 4 Mbit density is required in a small SOP-8 form factor. It is appropriate for designs needing industrial temperature stability (-40°C to +85°C). Consider it for applications where 2.7V to 3.6V operation fits the power budget. Evaluate the 108 MHz performance against higher-speed alternatives if bandwidth is critical. Ensure the SOP-8 footprint matches the target board layout constraints.

Memory IC Part Context

This part belongs to the Macronix MX25V series, which focuses on automotive-grade reliability and industrial temperature ranges. The series typically includes variants with different packages such as WSON and USON. The MX25V4035 family provides consistent electrical specifications across package types, allowing designers to choose based on space limitations while maintaining functional parity.

Memory IC Replacement Considerations

Check for MX25V4035FZNI or MX25V4035FZUI if smaller packages like WSON-8 or USON-8 are needed. Verify MX25V4035FM1I for alternative SOP-8 sourcing if available. Confirm pinout compatibility before substituting any variant within the MX25V4035 family.
