9.
The memory organization of the CIP-51 System Controller is similar to that of a standard 8051. There are
two separate memory spaces: program memory and data memory. Program and data memory share the
same address space but are accessed via different instruction types. The memory organization of the
C8051F91x-C8051F90x device family is shown in Figure 9.1
Note: Code compatible devices with up to 64 kB Flash and 4 kB RAM are available as the C8051F93x-92x family.
