PIC18F2XJXX/4XJXX FAMILY
2.1.1
PIC18FXXJXX devices have an internal core voltage
regulator. On these devices (“PIC18F” in the part num-
ber), the regulator is always enabled. The regulator
input is taken from the microcontroller V
output of the regulator is supplied to the V
pin. On these devices, this pin simultaneously serves
as both the regulator output and the microcontroller
core power input pin. For these devices, the
V
nothing else.
PIC18LFXXJXX devices do not have an internal core
voltage regulator. On these devices (“PIC18LF” in the
part number), power must be externally supplied to
both V
Whether or not the regulator is used, it is always good
design practice to have sufficient capacitance on all
supply pins. Examples are shown in Figure 2-3.
The specifications for core voltage and capacitance are
listed in Section 6.0 “AC/DC Characteristics Timing
Requirements for Program/Verify Test Mode”.

The PIC18F2XJXX/4XJXX family of devices offers
program memory sizes of 16, 32 and 64 Kbytes. The
memory sizes for different members of the family are
shown in Table 2-2. The overall memory maps for all
the devices are shown in Figure 2-4.
TABLE 2-2:
For purposes of code protection, the program memory
for every device is treated as a single block. Enabling
code protection, thus protects the entire code memory,
and not individual segments.
The Configuration Words for these devices are located
at addresses, 300000h through 300007h. These are
implemented as three pairs of volatile memory regis-
ters. Each register is automatically loaded from a copy
stored at the end of program memory. For this reason,
the top four words (or eight bytes) of the code space
(also called the Flash Configuration Words) should be
written with configuration data and not executable
code. The addresses of the Flash Configuration Words
are also listed in Table 2-2. Refer to section Section 5.0
“Configuration Word” for more information.
Locations, 3FFFFEh and 3FFFFFh, are reserved for
the device ID bits. These bits may be used by the
programmer to identify what device type is being pro-
grammed and are described in Section 5.1 “Device ID
Word”. These device ID bits read out normally, even
after code protection.
