4.6 Memory
4.6.1 SRAM
All RCM5400W modules have 512K of battery-backed data SRAM installed at U3, and
512K or 1 MB of fast SRAM are installed at U2 and at U11.
4.6.2 Flash Memory
All RCM5400W modules also have 512K or 1MB of flash memory installed at U4 or U12.
NOTE: Rabbit recommends that any customer applications should not be constrained by
the sector size of the flash memory since it may be necessary to change the sector size
in the future.
Writing to arbitrary flash memory addresses at run time is strongly discouraged. Instead,
define a “user block” area to store persistent data. The functions writeUserBlock()
and readUserBlock() are provided for this. Refer to the Dynamic C Function Refer-
ence Manual
for additional information.
4.6.3 Serial Flash
Up to 2MB of serial flash memory is available to store data and Web pages. Sample pro-
grams in the SAMPLES\RCM5400W\Serial_Flash folder illustrate the use of the
serial flash memory.
