General Description

USB to HomePNA

The Kawasaki KL5KUSB111 Controller is a unique single chip solution developed to interface the Universal Serial

Bus (USB) to HomePNA-Networks and standard 10base-T Networks. The KL5KUSB111 has been specifically

designed to provide a simple solution to communicate with Home Networking Applications at 1 Mb/s and/or 10 Mb/s

Ethernet. By utilizing the Kawasaki's USB to Ethernet technology that has been used throughout the industry. The

USB controller consists of a central 16-bit processor, mask ROM, RAM buffer, clock generator, HomePNA /

Ethernet interface, UART, IRQ, Watchdog Timer, Serial interface, External Memory Interface and Debug UART.

The SIE (Serial Interface Engine) is fully compatible with the USB specification. The Kawasaki USB to HomePNA

controller enables the advantages of Home Networking such as Shared Internet access, Printer/peripheral

sharing, File and application sharing and Networked gaming.
