3.7 Memory
surface-mounted “jumpers”
described in this section are found.
3.7.1 SRAM
The BL2000 is designed to accept 128K to 512K of SRAM packaged in an SOIC case.
The standard models come with 128K of SRAM. Table 3 lists the jumper settings for the
jumpers used to set the SRAM size. The “jumpers” are 0
surface-mounted resistors.
3.7.2 Flash Memory
The BL2000 is also designed to accept 128K to 512K of flash memory packaged in a
TSOP case.
The BL2000 comes with one 256K flash memory. Table 3 lists the jumper settings for the
jumpers used to set the SRAM size. The “jumpers” are 0
surface-mounted resistors.
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.
A Flash Memory Bank Select jumper configuration option exists at JP2 with 0
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 program. See Technical Note 218, Implementing a Serial Download Man-
ager for a 256K Flash, for details.
