XR22804 Hi-Speed USB to 10/100 Ethernet Bridge with 4 UARTs General Description The XR22804 is a Hi-Speed USB 2.0 compound device with an embedded hub and 7 downstream USB functions: 10/100 Ethernet MAC and Phy, 4 UARTs, multi-master capable I2C controller, and an Enhanced Dedicated GPIO Entity (EDGE) controller. The upstream USB interface has an integrated USB 2.0 PHY and device controller that is compliant with both Hi-Speed (480Mbps) and Full-Speed (12Mbps) USB 2.0. The vendor ID, product ID, power mode, remote wakeup support and maximum power consumption are amongst the values that can be programmed using the on-chip One-Time Programmable (OTP) memory. The 10/100 Ethernet MAC and PHY is compliant with IEEE 802.
