5.0
There are two types of memory in PIC18 Flash
microcontroller devices:
• 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.
Additional detailed information on the operation of the
Flash program memory is provided in Section 6.0
“Flash Program Memory”.

PIC18F87J11 FAMILY
5.1
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 will return all ‘0’s (a
NOP instruction).
The entire PIC18F87J11 Family of devices offers three
different on-chip Flash program memory sizes, from
64 Kbytes (up to 16,384 single-word instructions) to
128 Kbytes (65,536 single-word instructions). The
program memory maps for individual family members
are shown in Figure 5-3.
