PIC18F2XXX/4XXX FAMILY
1.0 DEVICE OVERVIEW
This document includes the programming specifications
for the following devices:
2.0 PROGRAMMING OVERVIEW
PIC18F2XXX/4XXX family devices can be
programmed using either the high-voltage In-Circuit
Serial Programming™ (ICSP™) method or the
low-voltage ICSP method. Both methods can be done
with the device in the user’s system. The low-voltage
ICSP method is slightly different than the high-voltage
method and these differences are noted where
applicable.
This programming specification applies to the
PIC18F2XXX/4XXX family devices in all package
types.
2.1 Hardware Requirements
In High-Voltage ICSP mode, PIC18F2XXX/4XXX
family devices require two programmable power sup-
plies: one for VDD and one for MCLR/VPP/RE3. Both
supplies should have a minimum resolution of 0.25V.
Refer to Section 6.0 “AC/DC Characteristics Timing
Requirements for Program/Verify Test Mode” for
additional hardware parameters.
2.1.1 LOW-VOLTAGE ICSP
PROGRAMMING
In Low-Voltage ICSP mode, PIC18F2XXX/4XXX
family devices can be programmed using a V
DD
source in the operating range. The MCLR/VPP/RE3
does not have to be brought to a different voltage, but
can instead be left at the normal operating voltage.
Refer to Section 6.0 “AC/DC Characteristics Timing
Requirements for Program/Verify Test Mode” for
additional hardware parameters.
2.2 Pin Diagrams
The pin diagrams for the PIC18F2XXX/4XXX family
are shown in Figure 2-1 and Figure 2-2.
