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.

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 EEPROM^TMinterface supported

Separate power supply Link and PHY
