PIC18F2XK20/4XK20

Flash Memory Programming Specification

1.0

DEVICE OVERVIEW

2.1

Hardware Requirements

This

document

includes

the

programming

specifications for the following devices:

•

PIC18F23K20

PIC18F24K20

PIC18F25K20

PIC18F26K20

PIC18F43K20

PIC18F44K20

PIC18F45K20

PIC18F46K20

In High-Voltage ICSP mode, the PIC18F2XK20/4XK20

devices require two programmable power supplies:

one for V

and one for MCLR/V

/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

2.0

PROGRAMMING OVERVIEW

The PIC18F2XK20/4XK20 devices can be pro-

grammed 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 users’ system. The low-voltage ICSP

method is slightly different than the high-voltage

method and these differences are noted where applica-

ble. This programming specification applies to the

PIC18F2XK20/4XK20 devices in all package types.

In Low-Voltage ICSP mode, the PIC18F2XK20/4XK20

devices can be programmed using a single V

source

in the operating range. The MCLR/V

/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.
