4.6 Memory
4.6.1 SRAM
PowerCore FLEX modules running at 51.6 MHz need 512K of program-execution SRAM
at U13, which is not battery-backed. The battery-backed data SRAM at U2 on all Power-
Core modules is 256K–512K.
4.6.2 Flash EPROM
PowerCore modules also have 512K of flash EPROM installed at U3.
Writing to arbitrary flash memory addresses at run time is also discouraged. Instead, use a
portion of the “user block” area to store persistent data. The functions writeUser-
Block and readUserBlock are provided for this. Refer to the
cessor Designer’s Handbook
A Flash Memory Bank Select jumper configuration option based on 0 Ω surface-mounted
resistors exists at JP2 on the PowerCore module. This option is reserved for future use.
4.6.3 Serial Flash
A serial flash is an available option on PowerCore FLEX modules to store data and Web
pages. Sample programs in the SAMPLES\PowerCoreFLEX folder illustrate the use of
the serial flash. These sample programs are described in Section 3.2.4, “Use of Serial
Flash.”
4.6.4 Dynamic C BIOS Source Files
The Dynamic C BIOS source files handle different standard RAM and flash EPROM sizes
automatically.
User’s Manual
NOTE: Rabbit Semiconductor recommends that any customer applications should not be
constrained by the sector size of the flash EPROM since it may be necessary to change
the sector size in the future.
