Description
The XR22800 is a Hi-Speed USB 2.0 compound device with an embeddedhub and 3 downstream USB functions: 10/100 Ethernet Controller,multi-master capable I2C controller, and an Enhanced Dedicated GPIOEntity (EDGE) controller.The upstream USB interface has an integrated USB 2.0 PHY and devicecontroller that is compliant with both Hi-Speed (480Mbps) and Full-Speed(12Mbps) USB 2.0. The vendor ID, product ID, power mode, remotewakeup support and maximum power consumption are amongst the valuesthat can be programmed using the on-chip One-Time Programmable(OTP) memory.The Ethernet controller has an integrated 10/100 Ethernet MAC and PHYand is compliant with IEEE 802.3. The Ethernet controller supports autonegotiation,auto-MDIX, checksum offload, auto-polarity correction in10Base-T and remote wakeup capabilities.The multi-master capable I2C controller and EDGE controller (8 GPIOs)can be accessed via the USB HID interface. The EDGE pins or I2C interfacecan be used for controlling and monitoring other peripherals. Up to 2EDGE pins can be configured as a PWM generator
