PIC18F46J50 FAMILY
6.0
MEMORY ORGANIZATION
There are two types of memory in PIC18 Flash
microcontrollers:
Program Memory
Data RAM
As Harvard architecture devices, the data and program
memories use separate busses; this allows for
concurrent access of the two memory spaces.
provides
additional information on the operation of the Flash
program memory.
6.1
Program Memory Organization
PIC18 microcontrollers implement a 21-bit Program
Counter, which is capable of addressing a 2-Mbyte
program memory space. Accessing a location between
the upper boundary of the physically implemented
memory and the 2-Mbyte address returns all ‘0’s (a
NOP
instruction).
The PIC18F46J50 family offers a range of on-chip
Flash program memory sizes, from 16 Kbytes (up to
8,192
single-word
instructions)
to
64 Kbytes
(32,768 single-word instructions).
Figure 6-1 provides the program memory maps for
individual family devices.
