RabbitCore RCM3305/RCM3315
4.5 Memory
4.5.1 SRAM
RCM3305/RCM3315 boards have 512K of program-execution fast SRAM at U11. The
program-execution SRAM is not battery-backed. There are 512K of battery-backed data
SRAM installed at U10.
4.5.2 Flash EPROM
RCM3305/RCM3315 boards also have 512K of flash EPROM at U9.
NOTE: Rabbit 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.
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 Rabbit 3000
Microprocessor Designer’s Handbook
and the Dynamic C Function Reference Manual for
additional information.
4.5.3 Serial Flash
A serial flash is supplied on the RCM3305 and the RCM3315 to store data and Web pages.
Sample programs in the SAMPLES\RCM3300 folder illustrate the use of the serial flash.
These sample programs are described in Section 3.2.1, “Use of Serial Flash.”
4.5.4 Dynamic C BIOS Source Files
The Dynamic C BIOS source files handle different standard RAM and flash EPROM sizes
automatically.
