3.4 Memory
3.4.1 SRAM
The Intellicom is designed to accept 32K to 512K of SRAM packaged in an SOIC case.
The standard models come with 128K of SRAM. Figure 12 shows the locations and the
jumper settings for the jumpers at JP1 used to set the SRAM size. The “jumpers” are 0 Ω
surface-mounted resistors.
3.4.2 Flash Memory
The Intellicom is also designed to accept 128K to 512K of flash memory packaged in a
TSOP case.
The Intellicom OP6700 comes with two 256K flash memory chips, and the Intellicom
OP6600 comes with one 256K flash memory. Figure 12 shows the locations and the
jumper settings for the jumpers at JP2 and JP3 used to set the flash memory size. The
“jumpers” are 0 Ω surface-mounted resistors.
A Flash Memory Bank Select jumper configuration option exists at JP5 with 0 Ω surface-
mounted resistors. 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 manager and a separate downloaded pro-
gram. See Technical Note 218, Implementing a Serial Download Manager for a 256K
Flash, for details.
3.4.3 Dynamic C BIOS Source Files
The Dynamic C BIOS source files handle different standard RAM and flash EPROM sizes
automatically.

NOTE: Rabbit recommends that any customer applications should not be constrained by
the sector size of the flash EPROM since it may be necessary to change the sector size
in the future.
