EM2000IP is a high performance USB 2.0 Series Interface Engine (SIE). EM2000IP can integrates with USB 2.0 Transceiver Macrocell Interface (UTMI) PHY Interfaces, it Support 8/16 bit standard UTMI. The transceiver is controlled by input signals from the SIE bus, which is synchronized with the 12MHz clock. This SIE Support Control, Interrupt, Bulk and Isochronous transfer. For power management, EM2000IP also support Suspend, Resume and Reset function. This configurable SIE default as one Control endpoint, one Interrupt endpoint and two Isochronous endpoints. For the FIFO size and endpoints can be configurable upon request. EM2000IP with standard UTMI and 40X improvement in data rate can be easily adapted for implementation of USB 2.0 high speed compliant design of widely applications, including portable electronics device, handheld devices, high speed peripherals, printers, storages, PC cameras, flash card readers, and external CD-ROM/DVD-RW.     Support HS (480MHZ), FS (12MHZ) data transfer rate Support 8/16 bit standard USB 2.0 Transceiver Macrocell Interface (UTMI) PHY Interf Support Control, Interrupt, Bulk and Isochronous transfer Support Suspend, Resume and Reset functionality Default as one Control endpoint, one Interrupt endpoint and two Isochronous endpoints Customize FIFO size and endpoints for special request Single clock for easy synthesis and timing analysis
