Description

The XR22801 is a Hi-Speed USB 2.0 compound device with an embeddedhub and 4 downstream USB functions: 10/100 Ethernet Controller,UART, multi-master capable I2C controller, and an Enhanced DedicatedGPIO Entity (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 enhanced UART has a maximum data rate of 15 Mbps. Using a fractionalbaud rate generator, any baud rate between 300 bps and 15 Mbpscan be accurately generated. In addition, the UART has a large 1024-byteTX FIFO and RX FIFO to optimize the overall data throughput for variousapplications. The automatic RS485 control feature simplifies both thehardware and software for half-duplex RS-485 applications. If required,the multidrop (9-bit) mode feature further simplifies typical multidrop applicationsby enabling / disabling the UART receiver depending on theaddress byte received.The multi-master capable I2C controller and EDGE controller (up to 16GPIOs) can be accessed via the USB HID interface. The EDGE pins orI2C interface can be used for controlling and monitoring other peripherals.Up to 2 EDGE pins can be configured as a PWM generator
