UPD72870 Description
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 ply with the P1394a draft 2.0 specifications and the OpenHCI IEEE1394 1.0 and work up to 400 Mbps. These make design so pact for PC and PC card application.
