KL5KUSB220
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.
