11. Memory Organization and SFRs
The memory organization of the C8051F350/1/2/3 is similar to that of a standard 8051. There are two sep-
arate 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 map is shown in Figure 11.1.
11.1. Program Memory
The CIP-51 core has a 64 kB program memory space. The C8051F350/1/2/3 implements 8 kB of this pro-
gram memory space as in-system, re-programmable Flash memory, organized in a contiguous block from
addresses 0x0000 to 0x1DFF. Addresses above 0x1DFF are reserved.
Program memory is normally assumed to be read-only. However, the C8051F350/1/2/3 can write to pro-
gram memory by setting the Program Store Write Enable bit (PSCTL.0) and using the MOVX write instruc-
tion. This feature provides a mechanism for updates to program code and use of the program memory
space for non-volatile data storage. Refer to Section “15. Flash Memory’ on page 121 for further details.
