Winbond’s W25Q SpiFlash® Multi-I/O Memories feature the popular Serial Peripheral Interface (SPI), densities from 512Kbit to 2G-bit, small erasable sectors and the industry’s highest performance. The W25Q family with Dual-I/O and QuadI/O SPI offers even higher performance. Clock rates up to 133MHz achieve an equivalent of 532MHz (66M-Byte/s transferrate) when using Quad-SPI. Faster transfer rates mean controllers can execute code (XIP) directly from the SPI interfaceor further improve boot time when shadowing code to RAM. Some SpiFlash® devices offer the new Quad Peripheral Interface (QPI) supporting true Quad Commands for improved XIP performance and simpler controller circuitry. Additionally, new ultra-small form-factor packages are ideal for space constrained mobile and handheld applications.

Winbond’s W25X and W25Q SpiFlash ® Multi I/O memory supports a universal SPI interface, with capacities ranging from 512Kb to 512Mb, and features small capacity split erasable blocks and industry performance. The W25X series supports Dual SPI dual line output input mode, which is equivalent to doubling 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 output input mode to provide higher performance. The operating frequency of 104MHz is equivalent to 416MHz (50M Byte/S transmission rate), which is equivalent to four times the performance of typical single wire SPI operations. The W25Q series not only outperforms Parallel flash in performance, but also offers packaging with fewer pins.

A faster transmission rate means that the controller can directly execute on-chip (XIP, eXecute In Place) with flash memory through the SPI interface, or accelerate the copying of code to RAM for faster startup speed. In addition, some SpiFlash supports QPI (Quad Peripheral Interface) to enable faster instruction set transfer and accelerate the transfer efficiency of XIP. In addition, smaller packaging is more conducive to the application of handheld and mobile devices with limited design space.

In terms of shipment quantity and revenue of Serial Flash, Winbond is in an advanced position. Memory products with TS16949 and AEC-Q100 certifications can be applied to automobiles. Nowadays, cars have begun to adopt more precision 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 driver’s center console. By using a smaller SpiFlash memory package, limited space designs can use higher memory capacity in more advanced applications.
