PIC18F2XXX/4XXX FAMILY
1.0DEVICE OVERVIEW
This document includes the programming specifications for the following devices:
2.0PROGRAMMING 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.
2.1Hardware Requirements
In High-Voltage ICSP mode, PIC18F2XXX/4XXX Family devices require two programmable power supplies: one for
VDDand 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.
2.1.1LOW-VOLTAGE ICSP PROGRAMMING
In Low-Voltage ICSP mode, PIC18F2XXX/4XXX Family devices can be programmed using a VDDsource 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.
2.2Pin Diagrams
The pin diagrams for the PIC18F2XXX/4XXX Family are shown in Figure 2-1, Figure 2-2, Figure 2-3, Figure 2-4,
Figure 2-5.
