The FC-AL host controller ASIC has a 64-bit, 66 MHz PCI (EPCI) interface. The
controller contains the serializer/deserializer (SERDES) and the transceivers on-chip.
The host controller implements the Fibre Channel protocol through a microcoded
engine. The memory for the firmware is external and is implemented with
synchronous 128 Kilobyte SRAM. This memory also keeps the context data for
outstanding I/Os.
