The W25Q128 (128M-bit) Serial Flash memory is an efficient storage solution for systems with constraints on space, pins, and power. Part of the 25Q series, it delivers performance and versatility that surpasses typical Serial Flash devices. It’s perfect for applications like code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP), and storing data such as voice and text. The device operates on a single 2.7V to 3.6V power supply and features low current consumption, as low as 1µA during power-down. All models come in compact, space-saving packages.
