3.3.2 Memory
3.3.2.1 SRAM
The Smart Star CPU Cards are designed to accept 128K or 512K of static RAM packaged
in an SOIC case. Standard CPU Cards come with 128K of SRAM.
3.3.2.2 Flash EPROM
The Smart Star CPU Card are also designed to accept 128K to a total of 512K of flash
memory packaged in a TSOP case. The CPU cards come with two 256K flash memory
chips.
A Flash Memory Bank Select jumper configuration option based on 0 Ω surface-mounted
resistors exists at header JP5 on the CPU Card. This option, used in conjunction with some
configuration macros, allows Dynamic C to compile two different co-resident programs
for the upper and lower halves of the 256K flash in such a way that both programs start at
logical address 0000. This is useful for applications that require a resident download man-
ager and a separate downloaded program. See Technical Note 218, Implementing a Serial
Download Manager for a 256K Flash, for details.

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.
