11. 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 memory organization is shown in
Figure 11.1
11.1. Program Memory
The CIP-51 core has a 64 kB program memory space. The C8051F55x/56x/57x devices implement 32 kB
or 16 kB of this program memory space as in-system, re-programmable Flash memory, organized in a con-
tiguous block from addresses 0x0000 to 0x7FFF in 32 kB devices and addresses 0x0000 to 0x3FFF in
16 kB devices. The address 0x7BFF in 32 kB devices and 0x3FFF in 16 kB devices serves as the security
lock byte for the device. Addresses above 0x7BFF are reserved in the 32 kB devices.
