PIC16F/LF720/721

PIC16F/LF720/721 Flash Memory Programming Specification

This document includes the

programming specifications for the

following devices:

• PIC16F720

• PIC16LF720

• PIC16F721

• PIC16LF721

1.1

Hardware Requirements

PIC16F/LF720 and PIC16F/LF721 devices require one

power supply for V

and one for MCLR/V

. (See

Section 8.0 “Electrical Specifications”

for more

details.)

1.2

Pin Utilization

Five pins are needed for ICSP™ programming. The

pins are listed in Table 1-1.

1.0

OVERVIEW

The PIC16F/LF720 and PIC16F/LF721 devices are

programmed using In-Circuit Serial Programming™

(ICSP™). This programming specification applies to

the PIC16F/LF720 and PIC16F/LF721 devices in all

packages.

With the exception of memory size and the voltage reg-

ulator, all other aspects of the PIC16F/LF720 and

PIC16F/LF721 devices are identical.

Legend:

I = Input, O = Output, P = Power

Note 1:

To activate the Program/Verify mode, high voltage needs to be applied to MCLR/V

input. Since the

MCLR /V

is used for a level source, MCLR/V

does not draw any significant current.
