PRELIMINARY DATA SHEET

MOS INTEGRATED CIRCUIT

µPD72870,72871

IEEE1394 1-CHIP OHCI HOST CONTROLLER

The µPD72870, 72871 are the LSIs which integrated OHCI-Link and PHY function into a single chip.

The µPD72870, 72871 comply with the P1394a draft 2.0 specifications and the OpenHCI IEEE1394 1.0 and work

up to 400 Mbps.

These make design so compact for PC and PC card application.
