9. 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 of the
C8051F96x device family is shown in Figure 9.1
9.1. Program Memory
The C8051F960/1/2/3 device flashs have a 128 kB program memory space, C8051F964/5 devices have
64 kB program memory space, C8051F966/7 devices have 32 kB program memory space, and
C8051F968/9 devices have a 16 kB program memory space. The devices with 128 kB flash implement this
program memory space as in-system re-programmable flash memory in four 32 kB code banks. A com-
mon code bank (Bank 0) of 32 kB is always accessible from addresses 0x0000 to 0x7FFF. The upper code
banks (Bank 1, Bank 2, and Bank 3) are each mapped to addresses 0x8000 to 0xFFFF, depending on the
