W25Q128FVEAQ

Memory IC Overview

The W25Q128FVEAQ is a 128M-bit (16M x 8) serial NOR Flash memory component manufactured by Winbond Electronics. It utilizes an SPI interface supporting Quad I/O and QPI modes with a clock frequency of 104 MHz. The device operates within a voltage range of 2.7V to 3.6V and features an 8-pin WDFN-8 package with exposed pad. It supports uniform sector architecture and functions across a temperature range of -40°C to 85°C.

Memory IC Feature Summary

• Provides non-volatile storage for firmware and data in embedded systems
• Supports high-speed serial communication via SPI, Quad I/O, and QPI interfaces
• Features compact surface-mount packaging suitable for space-constrained designs

Memory IC Applications

• Embedded system firmware storage
• Consumer electronics data logging
• Industrial control system code execution

Memory IC Procurement Notes

Verify the specific suffix 'EAQ' against official Winbond documentation to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with existing PCB footprints for the WDFN-8 package. Confirm RoHS compliance status through current manufacturer certificates before finalizing procurement.

Memory IC Selection Notes

Select this component when a 128Mb capacity is required with Quad I/O support for higher throughput. The WDFN-8 package offers a smaller footprint compared to SOIC options. Verify that the operating voltage range aligns with the system's power supply rails and that the thermal performance meets the application's environmental conditions.

Memory IC Part Context

This part belongs to the W25Q series of SpiFlash memories from Winbond Electronics. The series is designed for general-purpose storage applications requiring reliable non-volatile data retention. The W25Q128 variant specifically provides 128 megabits of storage organized in uniform sectors for flexible erase operations.

Memory IC Replacement Considerations

Check for direct substitutes such as W25Q128JVSIQ or W25Q128FVSIG if availability is an issue. Verify pin compatibility and package dimensions before substitution. Review datasheets for any differences in speed grades or voltage tolerances between original and replacement parts.
