3.0
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 busses; this allows for concur-
rent 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 4.0
“Flash Program Memory”. Data EEPROM is
discussed separately in Section 5.0 “Data EEPROM
Memory”.

PIC18F1XK22/LF1XK22
3.1
PIC18 microcontrollers implement a 21-bit program
counter, which is capable of addressing a 2-Mbyte
Program Memory (PC) 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:
• PIC18F13K22/LF13K22: 8 Kbytes of Flash Mem-
• PIC18F14K22/LF14K22: 16 Kbytes of Flash Mem-
PIC18 devices have two interrupt vectors and one
Reset vector. The Reset vector address is at 0000h
and the interrupt vector addresses are at 0008h and
0018h.
The program memory map for PIC18F1XK22/
LF1XK22 devices is shown in Figure 3-1. Memory
block details are shown in Figure 22-2.
