PIC16F716
This document includes the
programming specifications for the
following devices:
• PIC16F716
1.0 PROGRAMMING THE
PIC16F716
The PIC16F716 is programmed using a serial method.
The Serial mode will allow the PIC16F716 to be
programmed while in the user’s system. This allows for
increased design flexibility. This programming
specification applies to PIC16F716 devices in all
packages.
1.1 Hardware Requirements
The PIC16F716 requires one power supply for VDD
(5.0V) and one for VPP (12V).
1.2 Program/Verify Mode
The Program/Verify mode for the PIC16F716 allows
programming of user program memory, special
locations used for ID, and the configuration word.

Note 1: In the PIC16F716, the programming high voltage is internally generated. To activate the Program/Verify
mode, high voltage of I
IHH current capability (see Table 5-1) needs to be applied to MCLR input.
