EZ-USB FX1 (CY7C64713/4) is a full-speed highly integrated, USB microcontroller. By integrating the USB transceiver, serial interface engine (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. Because it incorporates the USB transceiver, the EZ-USB FX1 is more economical, providing a smaller footprint solution than USB SIE or external transceiver implementations. With EZ-USB FX1, the Cypress Smart SIE handles most of the USB 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. Three lead-free packages are defined for the family: 56 QFN, 100 TQFP, and 128 TQFP.
