On-Board Memory

May 2013 Altera Corporation Stratix III 3SL150 Development Board

Reference Manual

Table 2–56 shows the flash on-board memory map. The memory needs to provide

non-volatile storage of a minimum of eight FPGA bit streams as well as various

settings data used for on-board devices such as Ethernet TCP/IP defaults, PFL

configuration bits, and data on the board itself. The remaining area is designated as

user flash area for storage of software binaries and other data relevant to a user FPGA

design.
