MX25U12872FZNI02

Memory IC Overview

The MX25U12872FZNI02 is a 128M-bit Serial NOR Flash memory from Macronix, operating on a single 1.65V to 2.0V power supply. It features the MXSMIO architecture supporting Single, Dual, and Quad I/O protocols with clock frequencies up to 133MHz. The device utilizes an 8-land WSON (6x5mm) package and includes a permanently fixed QE bit for immediate Quad I/O enablement. It supports Execute-in-Place (XIP), program/erase suspend/resume, and advanced security features including block lock protection and an 8K-bit secured OTP.

Memory IC Procurement Notes

Verify the specific ordering suffix ZNI02 against the manufacturer's datasheet to confirm the exact package type and tape/reel specifications. Ensure compatibility with the required voltage range of 1.65V to 2.0V for your system design. Confirm that the 8-land WSON (6x5mm) footprint matches your PCB layout constraints. Check for any regional distribution restrictions or lead time variations directly with authorized suppliers.

Memory IC Selection Notes

Select this component when a low-voltage 128M-bit NOR Flash with high-speed Quad I/O capabilities is required. The permanently fixed QE bit simplifies initialization compared to devices requiring software configuration for quad mode. Consider the 8-land WSON package if space-constrained surface mount solutions are necessary. Ensure the application benefits from the included hardware reset pin and advanced security features for robust system operation.

Memory IC Part Context

This part belongs to the MX25U series of CMOS MXSMIO Serial NOR Flash memories by Macronix. The series is characterized by its support for multiple I/O modes and low-voltage operation. The MX25U12872F variant specifically targets 128M-bit capacity requirements within this family, offering a balance of performance and density for modern embedded applications.

Memory IC Replacement Considerations

Direct replacements must match the 128M-bit capacity, 1.8V operation, and 8-WSON package. Verify interface compatibility, particularly the permanently fixed QE bit behavior. Cross-reference command sets and timing parameters to ensure seamless integration without firmware modifications.
