PRELIMINARY DATA SHEET
MOS INTEGRATED CIRCUIT
µPD72873
IEEE1394 OHCI 1.1 COMPLIANT 2PORT PHY-LINK 1-CHIP HOST CONTROLLER
The µPD72873 is the LSI that integrated OHCI-Link and PHY function into a single chip. The µPD72873 complies
with the 1394 OHCI Specification 1.1 and the IEEE Std 1394a-2000 specifications, and works up to 400 Mbps.
It makes design so compact for PC and PC card application.
FEATURES
