KL5KUSB240

USB2.0 to PCI BUS

General Description

The Kawasaki KL5KUSB240 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 KL5KUSB240 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.

Features

• 33MHz PCI interface

• 30MHz USB 2.0 SIE BUS for High-Speed SIE

operation

• Double packet buffer - 512x2 HS, 64Bx2 FS

• Internal DMA operation between the High-Speed

SIE and Double Buffer

• Interfaces with USB 2.0 PHY

• PCI interface for Target and Master (2

DMA) modes

• Page and Descriptor DMA Modes

• USB data access by PCI target or DMA

• 0.35u Std cell technology

• Vdd = 3.3V, Ta = 0~70°C

• 144 pin LQFP package (20 mm2)
