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.

5 • Built-in FIFOs for isochronous transmit (1024 bytes), asynchronous transmit (1024 bytes), and receive (2048
bytes)
• 32-bit CRC generation and checking for receive/transmit packets
• 4 isochronous transmit DMAs and 4 isochronous receive DMAs supported
• 32-bit DMA channels for physical memory read/write
• Clock generation by 24.576 MHz X’tal
• Internal control and operational registers direct-mapped to PCI configuration space
• 2-wire Serial EEPROMTM interface supported
• Separate power supply Link and PHY
