[Kawasaki LSI]

General Description
The Kawasaki KL5KUSB121 Controller is a unique single chip solution to interface peripheral devices to the Universal Serial Bus (USB) and Ethernet. The KL5KUSB121 has been specifically designed to provide a simple solution to communicate with Ethernet applications as well as other USB peripheral 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.
