【关注图像采集视频传输】之CYUSB3014 EZ-USB FX3 Software Development Kit

网址：http://www.cypress.com。与之前的High Speed FX2相比，新的产品叫Super Speed  FX3，沿用了之前的命名习惯。FX2芯片内嵌一个8051核，FX3则内嵌的是ARM926EJ核，核心运行频率达到了200MHz，芯片内的SRAM达到了512KB。

　　此外，增加了其它对串口的支持，如SPI总线，I2S总线，还有FX2就有的I2C总线，UART总线，但束度大幅提高。晶振频率也有所提高，最快的是52MHz，还有38,4MHz，26MHz，19.2MHz，用户可以自己选择。GPIF也升级到GPIF II，运行频率达到了100MHz。新增了HS-OTG功能，本身可以当USB主机。

Cypress delivers the complete software and firmware stack for FX3, in order to easily integrate SuperSpeed USB into any embedded application. The Software Development Kit (SDK) comes with tools, drivers and application examples which help accelerate application development. The SDK provides full firmware development and debug support on Windows, Linux and MacOS platforms.

The current version of the SDK supports all parts in the FX3 device family, including FX3S, CX3, SD3, FX2G2, Benicia and Bay. The FX3S, Benicia and SD3 devices add SD/MMC peripheral access support to the FX3 device. The CX3 devices provide a MIPI CSI interface that can connect directly to image sensors. The FX2G2 is a USB 2.0 only version of the FX3 device; and Bay is a USB 2.0 only version of the Benicia device. Please see the corresponding product pages for more information about each of the devices.
