Taiwan Winbond's W25X and W25Q SpiFlash ® Multi I/O memory supports a universal SPI interface with capacities ranging from 512Kb to 512Mb, featuring erasable blocks with small capacity partitioning and industry performance. The W25X series supports Dual SPI dual input/output mode, which doubles the operating frequency of the original standard SPI. The W25Q series is an advanced version of the 25X series, which supports Quad-I/O SPI four wire input/output mode to provide higher performance. The operating frequency of 104MHz is equivalent to 416MHz (50M-Byte/S transmission rate), which is four times the performance of a typical single wire SPI operation. The W25Q series not only outperforms Parallel Flash in performance, but also offers packaging with fewer pins. A faster transfer rate means that the controller can directly perform on-chip execution (XIP, eXecute In Place) with flash memory through the SPI interface, or speed up copying code to RAM to increase boot speed. In addition, some SpiFlash supports QPI (Quad Peripheral Interface) to enable faster transmission of instruction sets and improve XIP transmission efficiency. In addition, smaller packaging is more conducive to the application of handheld and mobile devices with limited design space.

        Winbond Electronics is in an advanced position in terms of the shipment quantity and revenue of Serial Flash. Memory products with TS16949 and AEC-Q100 certifications can be applied to automobiles. Nowadays, cars have begun to adopt more sophisticated electronic devices, such as digital display dashboards, which display 2D/3D graphics in real-time through fast processors and SpiFlash memory, providing more driving information to improve safety. Advanced Driver Assistance Systems (ADAS), entertainment, and navigation systems can now coexist in the driving center console. By using a smaller SpiFlash memory package, space limited designs can utilize higher memory capacity for more advanced applications.
