PRELIMINARY DATA SHEET
µPD72870,72871
IEEE1394 1-CHIP OHCI HOST CONTROLLER
MOS INTEGRATED CIRCUIT
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.
