Product Description
The ISP2200 is a single-chip, highly integrated, bus
master, Fibre Channel processor that targets storage,
clustering, and networking applications. This chip
connects the PCI bus to a Fibre Channel loop or to a
point-to-point Fibre Channel port.
The ISP2200 is pin compatible with the ISP2100A.
The ISP2200 is a fully autonomous device, capable of
managing multiple I/O operations and associated data
transfers from start to 鏗乶ish without host intervention.
The ISP2200 provides power management support in
accordance with the
PCI Bus Power Management Interface
Speci鏗乧ation.
The ISP2200 block diagram is illustrated in
鏗乬ure 1.
