Overview
The W25Q256JVFIQ is a 256M-bit Serial NOR Flash memory device produced by Winbond Electronics. This component is designed to provide a high-capacity storage solution for systems with limited space, pins, and power. It operates on a single 2.7V to 3.6V power supply and is available in various space-saving packages, including 16-pin SOIC, 24-ball TFBGA, and 8-pad WSON.
The device is part of the 25Q series, known for its flexibility and performance beyond ordinary Serial Flash devices. It supports Dual/Quad SPI interfaces, enabling fast data transfer rates and making it ideal for applications such as code shadowing to RAM, executing code directly from the flash (XIP), and storing voice, text, and data.
