PIC16(L)F720/721
This document includes the
programming specifications for the
following devices:
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
regulator, all other aspects of the PIC16F/LF720 and
PIC16F/LF721 devices are identical.
1.1 Hardware Requirements
PIC16F/LF720 and PIC16F/LF721 devices require one
power supply for V
DD and one for MCLR/VPP. (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.

Legend: I = Input, O = Output, P = Power
Note 1: To activate the Program/Verify mode, high voltage needs to be applied to MCLR/VPP input. Since the
MCLR
/VPP is used for a level source, MCLR/VPP does not draw any significant current.
