General Description

USB2.0 to 100 Ethernet Controller

The Kawasaki KL5KUSB220 Controller used in conjunction with the KL5KUSB200/201 USB2.0

transceiver is a unique solution to interface peripheral devices to the Universal Serial Bus 2.0

(USB2.0) and 100Base-T Ethernet. The KL5KUSB220 has been specifically designed to provide

a simple solution to communicate with Ethernet applications 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 and

Memory Interface. The SIE (Serial Interface Engine) is fully compatible with the USB2.0

specification. Our powerful internal processor enables Remote NDIS (Network Drive) which gives

compatibility with next generation operating systems and faster data transfer. 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.
