XR22800 Hi-Speed USB to 10/100 Ethernet Bridge FEATURES General Description USB 2.0 Compliant Interface The XR22800 is a Hi-Speed USB 2.0 compound device with an embed- 10/100 Ethernet MAC and PHY ded hub and 3 downstream USB functions: 10/100 Ethernet MAC and 2 I C Multi-master 2 PHY, multi-master capable I C controller, and an Enhanced Dedicated Enhanced Dedicated GPIO Entity (EDGE) GPIO Entity (EDGE) controller. Single +5.0V Power Supply Input The upstream USB interface has an integrated USB 2.0 PHY and device Regulated +3.3V Output Power controller that is compliant with both Hi-Speed (480Mbps) and Full-Speed Single 25MHz Crystal (12Mbps) USB 2.0. The vendor ID, product ID, power mode, remote wakeup support and maximum power consumption are amongst the val- 15kV HBM ESD Protection on USB data ues that can be programmed using the on-chip One-Time Programmable pins (OTP) memory. 8kV HBM ESD Protection on all other pins The 10/100 Ethernet MAC and PHY is compliant with IEEE 802.3 and USB CDC-ECM and HID compliant supports auto-negotiation, auto-MDIX, checksum offload, auto-polarity Custom Software Drivers correction in 10Base-T and remote wakeup capabilities. 2 APPLICATIONS The multi-master capable I C controller and EDGE controller (8 GPIOs) 2 USB to Ethernet Dongles can be accessed via the USB HID interface. The EDGE pins or I C inter- face can be used for controlling and monitoring other peripherals. Up to 2 POS Terminals EDGE pins can be configured as a PWM generator.
