Coyote (BL2500)

3.8 Memory

3.8.1 SRAM

The Coyote’s RabbitCore module is designed to accept 128K to 512K of SRAM packaged

in an SOIC case. The standard Coyote’s RabbitCore modules come with 128K of SRAM.

3.8.2 Flash Memory

The Coyote is also designed to accept 128K to 512K of flash memory. The standard

Coyote’s RabbitCore modules comes with one 256K flash memory.

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.

Writing to arbitrary flash memory addresses at run time is also discouraged. Instead, use a

portion of the “user block” area to store persistent data. The functions writeUserBlock

and readUserBlock are provided for this. Refer to the Rabbit 3000 Microprocessor

Designer’s Handbook

for additional information.

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.
