PRELIMINARY DATA SHEET
MOS INTEGRATED CIRCUIT
µPD72870A
IEEE1394 1-CHIP OHCI HOST CONTROLLER
The µPD72870A is the LSI which integrated OHCI-Link and PHY function into a single chip. The µPD72870A complies with the P1394a draft 2.0 specifications and the OpenHCI IEEE1394 1.0, and works up to 400 Mbps. It makes design so compact for PC and PC card application.
FEATURES
