KL5KUSB122 - USB Mini Host to 10/100 Ethernet - K-micro Datasheet

General Description
The Kawasaki KL5KUSB122 Controller is a unique single chip solution that serves as a bridge between USB and Ethernet interfaces. The USB side of the controller supports both USB Host and Device modes. The KL5KUSB122 has been specifically designed to provide Ethernet connectivity to USB devices. This has been accomplished by its highly integrated functionality. The USB controller consists of a central 16-bit processor, mask ROM, RAM buffer, clock generator, Ethernet interface, UART, IRQ, Watchdog Timer, Serial interface, External Memory Interface and SPORT Interface.
