3.8 Memory
3.8.1 SRAM
The BL2100 module is designed to accept 128K to 512K of SRAM packaged in an SOIC
case. The standard BL2100 modules come with 128K of SRAM.
3.8.2 Flash Memory
The BL2100 is also designed to accept 128K to 512K of flash memory packaged in a
TSOP case. The standard BL2100 modules comes with one 256K flash memory.
A Flash Memory Bank Select jumper configuration option based on 0  surface-mounted
resistors exists at header JP2 on the RabbitCore module. 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 pro-
grams start at logical address 0000. This is useful for applications that require a resident
download manager and a separate downloaded program. See Technical Note 218, Imple-
menting 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.
