12.2. Memory Organization
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. There are 256 bytes of internal data
memory and 64k bytes of internal program memory address space implemented within the CIP-51. The
CIP-51 memory organization is shown in Figure 12.2.
12.2.1. Program Memory
The CIP-51 has a 64 kB program memory space. The MCU implements 64 kB (C8051F040/1/2/3/4/5) and
32 kB (C8051F046/7) of this program memory space as in-system re-programmed Flash memory, orga-
nized in a contiguous block from addresses 0x0000 to 0xFFFF (C8051F040/1/2/3/4/5) and 0x0000 to
0x7FFF (C8051F046/7). Note: 512 bytes from 0xFE00 to 0xFFFF (C8051F040/1/2/3/4/5 only) of this mem-
ory are reserved for factory use and are not available for user program storage.
Program memory is normally assumed to be read-only. However, the CIP-51 can write to program memory
by setting the Program Store Write Enable bit (PSCTL.0) and using the MOVX instruction. This feature pro-
vides a mechanism for the CIP-51 to update program code and use the program memory space for non-
volatile data storage. Refer to
