IBM21S650PFA

1394 Serial Bus Link Layer PCI Controller

Features

• Fully IEEE 1394-1995 compatible

• General purpose IEEE 1394 Host Controller

• Asynchronous and isochronous capability

• Data rates: S100, S200, or S400Mb/s

• Uses DB DMA channel programs to communi-

cate with the device driver.

• Cycle Master capable

• ROM interface for external conﬁguration ROM

• PCI 2.1 compatible, with master and slave capa-

bilities

• Standard Link-PHY protocol and an Isolation

barrier between the link controller and the PHY

as described in IEEE 1394 Speciﬁcation,

Annex J

• 33MHz PCI bus support

• Parity error detection and report

• CMOS5S technology

• Transmits and receives packets larger than the

2KB internal buffer size.

• 3.3V power supply with 5.0V tolerant I/O

• 144 pin LQFP package

• Supports data chaining for packets and indi-

cates status of each package

Description

The IBM21S650PFA is a generic Link Layer Control-

ler for the 1394 serial bus using a PCI system inter-

face. It supports the transaction and bus

PCI to 1394 Interface System Example

management layers with an additional PHY device

and includes a DMA engine to reduce the CPU inter-

vention in transmitted or received packets.

CPU

Host Bridge

DRAM

PCI Bus

This link controller transmits and receives all types

of asynchronous packets, including cable physical

layer packets. It supports four isochronous DMA

channels, each of which can be programmed for

transmit or receive operation.

• Supports Packet-by-Packet and Contiguous

modes in receive.

• Supports Scatter & Gather of data in transmit

and receive operations.

• Supports cycle count information per packet for

receive.

The IBM21S650PFA has additional features. It can

function as PCI master, supporting cache line com-

mands, or as a PCI slave, supporting memory or

configuration access as a medium speed target.

During a 1394 bus reset, it receives the Self ID

packets from the PHY and forwards them to the sys-

tem memory. The link controller also has an external

port that allows direct access from the host CPU to

an expansion ROM or configuration ROM.

Use is further subject to the provisions at the end of this document.
