MEMORY ORGANIZATION
There are three types of memory in PIC18 Enhanced
microcontroller devices:
Program Memory
Data RAM
Data EEPROM
As Harvard architecture devices, the data and program
memories
use
separate
buses;
this
allows
for
concurrent access of the two memory spaces. The data
EEPROM, for practical purposes, can be regarded as
a peripheral device, since it is addressed and accessed
through a set of control registers.
Additional detailed information on the operation of the
Flash program memory is provided in Section 6.0
Data
EEPROM
is
discussed separately in Section 7.0 “Data EEPROM
5.1
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 will return all ‘0’s (a
NOP
instruction).
This family of devices contain the following:
PIC18(L)F23K22, PIC18(L)F43K22: 8 Kbytes of
Flash Memory, up to 4,096 single-word instructions
PIC18(L)F24K22, PIC18(L)F44K22: 16 Kbytes of
Flash Memory, up to 8,192 single-word instructions
PIC18(L)F25K22, PIC18(L)F45K22: 32 Kbytes of
Flash Memory, up to 16,384 single-word instruc-
tions
PIC18(L)F26K22, PIC18(L)F46K22: 64 Kbytes of
Flash Memory, up to 37,768 single-word
instructions
PIC18 devices have two interrupt vectors. The Reset
vector address is at 0000h and the interrupt vector
addresses are at 0008h and 0018h.
The program memory map for PIC18(L)F2X/4XK22
devices is shown in Figure 5-1. Memory block details
are shown in Figure 20-2.
