MX25U6472FM2I02

Memory IC Overview

The MX25U6472FM2I02 is a 64M-bit Serial NOR Flash memory from Macronix, organized as 8M x 8 internally. It operates on a single 1.65V to 2.0V power supply and supports SPI Mode 0 and Mode 3 protocols. The device features Single, Dual, and Quad I/O interfaces with clock frequencies up to 133 MHz. It includes a permanently fixed QE bit for 4 I/O mode, a 256-byte page buffer, and advanced security features like block lock protection and an 8K-bit secured OTP.

Memory IC Feature Summary

• Supports Single, Dual, and Quad I/O protocols with clock frequencies up to 133 MHz
• Features a permanently fixed Quad Enable (QE) bit enabling 4 I/O mode
• Includes advanced security with block lock protection and an 8K-bit secured OTP area
• Provides Program/Erase Suspend and Resume capabilities

Memory IC Applications

• Firmware storage in embedded systems
• Code execution via Execute-In-Place (XIP)
• Data logging applications requiring high endurance
• Consumer electronics with secure boot requirements

Memory IC Procurement Notes

Verify the specific suffix 'M2I02' against the manufacturer's ordering guide to confirm package type and tape/reel specifications. Ensure compatibility with the required voltage range of 1.65V to 2.0V. Check for RoHS compliance status if environmental regulations apply. Confirm lead times and availability directly with authorized distributors as stock levels fluctuate.

Memory IC Selection Notes

Select this component when a 64M-bit capacity is required with a low-voltage 1.8V operation profile. It is suitable for designs needing high-speed Quad I/O access without software configuration of the QE bit. Consider the 8-pin SOP package constraints and ensure the design supports the necessary SPI or QPI interface signals. Verify that the application benefits from the fixed QE feature to simplify firmware initialization.

Memory IC Part Context

This part belongs to the MX25U series of CMOS MXSMIO® Flash memories. It shares architectural similarities with other Macronix NOR flash devices but is distinct due to its 64M-bit density and fixed QE configuration. It complements lower-density variants like the MX25U8035 and higher-density options within the same family.

Memory IC Replacement Considerations

Direct replacements must match the 64M-bit capacity, 1.8V operation, and 8-SOP package. Verify pinout compatibility and command set adherence. Substitutes may require firmware adjustments if they do not have a permanently fixed QE bit or support different dummy cycle configurations.
