1. DESCRIPTION
The S1R72801F00A is a LINK/Transaction controller
based on the IEEE Std. 1394-1955, P1394a Draft 2.0. It
integrates a built-in CPU and Flash ROM, and also
integrates a part of transaction functions into hardware.
If you set a PageTable address and its size, it can
automatically fetch subsequent PageTables and transmit
data. It can offer a 1394 interface optimum to computer
peripherals in combination with the Cable PHY
Transceiver Arbiter based on the above standard.

2. FEATURES
q LINK/Transaction Controller
LINK Layer
Ready for all two-way data transfer in Asynchronous
and Isochronous modes.
The built-in SRAM realized stable two-way data
transfer up to max. payload of 100Mbps, 200Mbps,
and 400Mbps.
Can automatically detect the Isochronous Resource
Manager by hardware.
Transaction Layer
Integrates a part of transaction functions into hardware
to prevent deterioration of actual data transmission
rate due to the overhead of firmware (assure a special
area).
A header area is distinguished from a data area to
simplify communications with a higher rank layer.
Furthermore, it segments a data area to a stream area
and ORB area.
Adopts a ring buffer to the receive header area,
receive data area (receive stream area, receive ORB
area) and transmit data area (transmit stream area).
Can arbitrarily set the size of each area.
Automatically controls the Busy when hardware
receives data.
q SBP-2 Support
Can set an PageTable address and its size for the
SBP-2 to automatically perform subsequent Page
Table fetches and data transfers.
q PHY/LINK Interface
Ready for the P1394a.
Ready for the data transfer rate of 100/200/400Mbps.
Ready for isolation (bus holder integrated)
q IDE Interface
Ready for the PIO mode 0/1/2/3/4, multi-word DMA
mode 0/1/2, Ultra-DMA mode 0/1/2.
Usable as a general port interface as well.
