The Cypress EZ-USB(r) FX2 is the world’s first USB 2.0 integrated microcontroller. By integrating the USB 2.0 transceiver, SIE, enhanced 8051 microcontroller, and a programmable peripheral interface in a single chip, Cypress has created a very cost-effective solution that provides superior time-to-market advantages. The ingenious architecture of FX2 results in data transfer rates of 480 Mb per second, the maximum allowable USB 2.0 bandwidth, while still using a low-cost 8051 microcontroller in a small 100 pin TQFP package. Because it incorporates the USB 2.0 transceiver, the FX2 is more economical, providing a smaller footprint solution than USB 2.0 SIE or external transceiver implementations. With EZ-USB FX2, the Cypress Smart SIE handles most of the USB 1.1 and 2.0 protocol in hardware, freeing the embedded microcontroller for application-specific functions and decreasing development time to ensure USB compatibility. The General Programmable Interface (GPIF) and Master/Slave Endpoint FIFO (8- or 16-bit data bus) provides an easy and glueless interface to popular interfaces such as ATA, UTOPIA, EPP, PCMCIA, and most DSP/processors.

Cypress provides development software called the “EZ-USB Control Panel” that allows you to test and debug your firmware without developing the host-based driver for your specific application. You can emulate the USB host controller commands and quickly test different packet sizes for both bulk and isochronous packets.
Source code for a general-purpose Windows device driver is provided by Cypress and you may modify it to your unique requirements.
Source code can be downloaded through the EZ-USB Control panel provided by Cypress or by the RS232 debug port with Keil C51 IDE.
