LSIFC909 Overview
The amount of SSRAM (1 Mbyte) determines the maximum number of
outstanding Request Messages (1024). This roughly equates to the
maximum number of outstanding I/O requests pending in the LSIFC909.
3.7.2 Flash ROM
The memory controller in the LSIFC909 also manages an optional Flash
ROM. If present, the Flash ROM is used to store the firmware for the
LSIFC909 IOP, and if desired, the INT 0x13 boot software.
If the Flash ROM is not used, then the host platform is responsible for
downloading the IOP firmware to the LSIFC909 through the PCI
interface. The LSIFC909 supports a diagnostic interface, enabled
through a sequence of commands issued to the PCI configuration space.
Firmware may be directly written to the LSIFC909 internal memory and
external SSRAM through the diagnostic interface. Details of this
implementation are available in the LSI Logic LSIFC909 Programming
Guide Flash ROM is needed for firmware storage if INT 0x13 boot
software is used.
The Flash ROM is accessed using the upper eight bits of the Memory
Interface. If a Flash ROM is to be used, then it should have a capacity
of 1 Mbyte with a maximum access time of 150 ns. Please see the
LSI Logic LSIFC909 Programming Guide for more information regarding
the programming of the Flash ROM.
3.7.3 Serial EEPROM
The serial EEPROM stores the World Wide Name, VPD, and other
vendor specific information. It is programmed using the host interface of
the LSIFC909. The required size of the EEPROM is 2 Kbytes.
Note:
The LSIFC909 uses a serial EPROM autodownload that is
set to run at 100 Kbits/s. Please refer to your serial EPROM
vendor data sheet for more information.
