MX25U4035FM1J

Memory IC Overview

The MX25U4035FM1J is a 4 Mbit Serial NOR Flash memory device manufactured by Macronix. It operates within a supply voltage range of 1.65 V to 2 V and supports SPI interface with Quad I/O capabilities. The component features a maximum clock frequency of 108 MHz and utilizes an 8-SOP (150mil) surface-mount package. It is designed for industrial temperature ranges, functioning reliably between -40°C and +105°C.

Memory IC Feature Summary

• Supports high-speed serial peripheral interface with quad input/output data bus width for efficient data transfer.
• Operates at low voltage levels suitable for power-sensitive embedded applications.
• Provides non-volatile storage with robust industrial-grade thermal stability.

Memory IC Applications

• Firmware storage in industrial control systems
• Code execution in space-constrained embedded devices
• Data logging in automotive electronics

Memory IC Procurement Notes

Verify the specific suffix 'T' or absence thereof against official datasheets, as packaging formats vary. Confirm the exact operating temperature grade required for your application environment. Ensure voltage compatibility with the 1.65V to 2V specification before integration. Check for moisture sensitivity level requirements during assembly processes.

Memory IC Selection Notes

Select this component when a small form factor SOP-8 package is required alongside industrial temperature ratings. Compare against MX25U4035FZUI if a smaller USON footprint is preferred. Ensure the system design accommodates the 1.8V nominal supply voltage constraints. Verify that the 4 Mbit capacity meets the specific firmware or data storage needs without excess overhead.

Memory IC Part Context

This part belongs to the MX25U series of low-voltage Serial NOR Flash memories from Macronix. It shares architectural similarities with other MX25U models but differs in capacity and package type. The series is characterized by its support for advanced read commands and low power consumption profiles typical of modern embedded memory solutions.

Memory IC Replacement Considerations

MX25U4035FM1I offers similar specifications with a different temperature range. MX25U4035FZUI provides the same electrical characteristics in a compact USON-8 package. Verify pinout compatibility and software command set alignment before substituting.
