6.0
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.
Section 7.0 “Flash Program Memory” provides
additional information on the operation of the Flash
program memory.

PIC18F47J53 FAMILY
6.1
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 PIC18F47J53 family offers a range of on-chip
Flash program memory sizes, from 64 Kbytes (up to
32,768
(65,536 single-word instructions).
Figure 6-1 provides the program memory maps for
individual family devices.
