General Description

USB2.0 to 100Base-T Ethernet Controller

The Kawasaki KL5KUSB221 Controller is a unique single chip solution to interface peripheral

devices to the Universal Serial Bus 2.0 (USB2.0) and 100Base-T Ethernet. The KL5KUSB221

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 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.
