The FW420 07 is the LSI imple-
mentation of a high performance,
PCI bus-based open host controller
for implementation of IEEE® 1394b
compliant systems and devices.
Link layer functions are handled by
the FW420 07, utilizing the on-
chip 1394b compliant link core.
A high-performance and cost-
effective solution for connecting
and servicing multiple IEEE 1394
(1394—1995, 1394a, and 1394b)
peripheral devices can be realized.

— Programmable burst size for PCI
data transfer.
— Supports PCI Bus Power
Management Interface
Specification v.1.1.
— Supports clockrun protocol per
PCI Mobile Design Guide.
— Global byte swap function.
