KL5BUDV002
USB2.0 to PCI BUS
General Description
The Kawasaki KL5BUDV002 is a high performance device that transfers data between the USB2.0 high-
speed BUS and the PCI 33MHz, 32 bit BUS. This device easily interfaces with our USB 2.0 transceivers,
the KL5KUSB200 and KL5KUSB201. The KL5BUDV002 is an ideal solution to convert a PCI device to a
USB2.0 interface with its HS_SIE USB2.0 Transceiver interface, 4 sets of high-speed bulk packet size
buffers, PCI interface and PCI master 2DMA channel support.
