3.9 Memory
3.9.1 SRAM
The BL2600 modules have 512K of program-execution SRAM packaged in an SOIC
case. The BL2600 modules also come with 256K of data SRAM.
3.9.2 Flash Memory
The BL2600 also has 512K of flash memory packaged in a TSOP case.
NOTE: Z-World 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 also discouraged. Instead,
define a "user block" area to store persistent data. The functions
are provided for this.

A Flash Memory Bank Select jumper configuration option based on 0 Ω surface-mounted
resistors exists at header JP4 on the RabbitCore module (BL2600) or at header JP1 on the
RabbitCore module (BL2610). 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 512K flash in such a way that both programs 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,
Manager for a 256K Flash
3.9.3 Serial Flash
Header J9 is provided to allow you to plug in a Z-World SF1000 serial flash. You may use
two ½" (12 mm) spacers with 4-40 × 3/4 screws and nuts to attach the SF1000 securely.
