MaxLinear XR22802IL56-F

The XR22802 is a Hi-Speed USB 2.0 compound device with an embedded hub and 5 downstream USB functions: 10/100 Ethernet MAC and PHY, 2 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 802.3 and supports auto-negotiation, auto-MDIX, checksum offload, auto-polarity correction in 10Base-T and remote wakeup capabilities. The enhanced UART has a maximum data rate of 15 Mbps. Using a fractional baud rate generator, any baud rate between 300 bps and 15 Mbps can be accurately generated. In addition, the UART has a large 1024-byte TX FIFO and RX FIFO to optimize the overall data throughput for various applications. The automatic RS485 control feature simplifies both the hardware and software for half-duplex RS-485 applications. If required, the multidrop (9-bit) mode feature further simplifies typical multidrop applications by enabling / disabling the UART receiver depending on the address byte received. The multi-master capable I²C controller and EDGE controller (up to 32 GPIOs) can be accessed via the USB HID interface. The EDGE pins or I²C interface can be used for controlling and monitoring other peripherals. Up to 2 EDGE pins can be configured as a PWM generator.
