Serial NOR Flash

SpiFlash® Memories with SPI, Dual-SPI, Quad-SPI and QPI

Winbond's W25X and W25Q SpiFlash® Multi-I/O Memories feature the popular Serial Peripheral Interface (SPI), densities from 512K-bit to 512M-bit, small erasable sectors and the industry's highest performance.

The W25X family supports Dual-SPI, effectively doubling standard SPI clock rates. The W25Q family is a "superset" of the 25X family with Dual-I/O and Quad-I/O SPI for even higher performance. Clock rates up to 104MHz achieve an equivalent of 416MHz (50M-Byte/S transfer rate) when using Quad-SPI. This is more than four times the performance of ordinary Serial Flash (50MHz) and even surpasses asynchronous Parallel Flash memories while using fewer pins and less space.

Faster transfer rates mean controllers can execute code with Execute in Place methods (XIP) directly from the SPI interface or 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 SpiFlash Memory

Leading the Serial Flash Market in unit sales and revenue, Winbond TS16949 certified AEC-Q100 qualified memories now support automotive applications. The automobile has transformed into the most sophisticated electronic device in the market. Digital displays in automotive dashboards provide more information about the car, and improve safety.

Instant-on and real time 2D/3D image rendering is achieved with fast processors and SpiFlash® memories. ADAS (Advanced Driver Assist Systems), comfort, entertainment, and navigation is now available in the center console and this is addressed with SpiFlash® memories using small packages for space constrained systems and high density for advanced applications.
