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. The CIP-51 memory organization is
8.2.1. Program Memory
The CIP-51 core has a 64k-byte program memory space. The C8051F300/1/2/3 implements 8192 bytes of
this program memory space as in-system, reprogrammable Flash memory, organized in a contiguous
block from addresses 0x0000 to 0x1FFF. Note: 512 bytes (0x1E00 - 0x1FFF) of this memory are reserved
for factory use and are not available for user program storage. The C8051F304 implements 4096 bytes of
reprogrammable Flash program memory space; the C8051F305 implements 2048 bytes of reprogramma-
ble Flash program memory space. Figure 8.2 shows the program memory maps for C8051F300/1/2/3/4/5
devices.

Figure 8.2. Program Memory Maps
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 Section “10. Flash Memory” on page 89 for further details.
