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 supplies: 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 VDD 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, Figure 2-2, Figure 2-3, Figure 2-4,

Figure 2-5.
