Memory Configuration
As illustrated in
Figure 6
, the DS89C430 incorporates two 8kB flash areas for on-chip program memory and 1kB of
SRAM for on-chip data memory or a particular range (400–7FF) of “alternate” program memory space. The
DS89C440 incorporates two 16kB flash memories and the DS89C450 incorporates two 32kB flash memories. The
DS89C430 uses an address scheme that separates program memory from data memory such that the 16-bit
address bus can address each memory area up to maximum of 64kB.
