XR22801  
Hi-Speed USB to 10/100 Ethernet Bridge  
FEATURES  
General Description  
USB 2.0 Compliant Interface  
The XR22801 is a Hi-Speed USB 2.0 compound device with an embed-  
ded hub and 4 downstream USB functions: 10/100 Ethernet MAC and  
10/100 Ethernet MAC and PHY  
Enhanced UART

PHY, UART, multi-master capable I C controller, and an Enhanced Dedi-  
cated GPIO Entity (EDGE) controller.  
2
I C Multi-master  
Enhanced Dedicated GPIO Entity (EDGE)  
Single +5.0V Power Supply Input  
Regulated +3.3V Output Power  
Single 25MHz Crystal  
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 val-  
ues that can be programmed using the on-chip One-Time Programmable  
(OTP) memory.  
±15kV HBM ESD Protection on USB data  
pins  
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.  
±±kV HBM ESD Protection on all other pins  
USB CDC-ACM, CDC-ECM and HID  
compliant  
Custom Software Drivers  
The enhanced UART has a maximum data rate of 15 Mbps. Using a frac-  
tional 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 multi-drop (9-bit) mode feature further simplifies typical multi-drop  
applications by enabling / disabling the UART receiver depending on the  
address byte received.  
APPLICATIONS  
USB to Ethernet Dongles  
POS Terminals  
Test Instrumentation  
Networking  
Factory Automation and Process Controls  
Industrial Applications  
2
The multi-master capable I C controller and EDGE controller (up to 16  
GPIOs) can be accessed via the USB HID interface. The EDGE pins or

I C interface can be used for controlling and monitoring other peripherals.  
Up to 2 EDGE pins can be configured as a PWM generator.
