USB to Ethernet Controller General Description
The Kawasaki KL5KUSB101 Controller is a unique single chip solution to interface peripheral devices to the Universal Serial Bus (USB) and Ethernet.
The KL5KUSB101 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.
The SIE (Serial Interface Engine) is fully compatible with the USB specification.
This USB to Ethernet controller is ideal for LAN (Local Area Network), HAN (Home Area Network), Cable Modem, Set Top Boxes, or Mobile Networking applications.
