KL5KUSB245

USB2.0 to PCI BUS with 2.0 Transceiver

General Description

The Kawasaki KL5KUSB245 is a high performance device that transfers data between the USB2.0 high-

speed BUS and the PCI 33MHz, 32 bit BUS. This 1 chip solution has USB 2.0 transceiver embedded

reducing space and cost. The KL5KUSB245 is an ideal solution to convert a PCI device to a USB2.0

Transceiver, HS_SIE USB2.0 Transceiver interface, 4 sets of high-speed bulk packet size buffers, PCI

interface and PCI master 2DMA channel support.
