3.6 Memory
3.6.1 SRAM
The OP6800 module is designed to accept 128K to 512K of SRAM. The standard OP6800
modules come with 128K of SRAM.
3.6.2 Flash Memory
The OP6800 is also designed to accept 128K to 512K of flash memory. The standard
OP6800 modules come with one 256K flash memory.
A Flash Memory Bank Select jumper configuration option based on 0 Ω 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 TN218,
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.
