4.6 Memory
4.6.1 SRAM
All RCM4200 modules have 512K of battery-backed data SRAM installed at U10, and the
RCM4200 model has 512K of fast SRAM installed at U12.
4.6.2 Flash EPROM
All RCM4200 modules also have 512K of flash EPROM installed at U11.
Writing to arbitrary flash memory addresses at run time is discouraged. Instead, define a
“user block” area to store persistent data. The functions writeUserBlock and
readUserBlock are provided for this. Refer to the
Designer’s Handbook
4.6.3 Serial Flash
Up to 8 Mbytes of serial flash memory is available to store data and Web pages. Sample
programs in the SAMPLES\RCM4200\Serial_Flash folder illustrate the use of the
serial flash memory.
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.
