Winbond推出SDRAM、DDR、Spi Flash系列解决Memory方案:
同步动态随机存取内存:16Mb SDRAM、64Mb SDRAM、128Mb SDRAM、256Mb SDRAM
Synchronous DRAM is designed to process data at the same clock speed as the CPU. Therefore, synchronous DRAM is regarded as the core component that is used in high speed processing of large volumes of data. Currently, its usage is expanding to various consumer electronics such as DTV, DSC, HDD and STB.
双倍数据传输速率同步动态随机存取内存:64Mb DDR、128Mb DDR、256Mb DDR
DDR SDRAM or double-data-rate synchronous dynamic random access memory is a type of memory used in computers and consumer electronics. It achieves greater bandwidth than the preceding single-data-rate SDRAM by transferring data on both the rising and falling edges of the clock signal.
串行式闪存:SpiFlash® Memories with SPI, Dual-SPI, Quad-SPI and QPI
Winbond's W25X and W25Q SpiFlashR 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 eight 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 (XIP) directly from the SPI interface or further improve boot time when shadowing code to RAM. Additionally, 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.
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.
