PIC12F519
This document includes the
programming specifications for the
following devices:
•PIC12F519
1.0 PROGRAMMING THE
PIC12F519
The PIC12F519 is programmed using a serial method.
The Serial mode will allow the PIC12F519 to be
programmed while in the user’s system. This allows for
increased design flexibility. This programming
specification applies to the PIC12F519 devices in all
packages.
1.1 Hardware Requirements
The PIC12F519 requires one power supply for VDD
(5.0V) and one for VPP (12.5V).
1.2 Program/Verify Mode
The Program/Verify mode for the PIC12F519 allows
programming of user program memory, user ID
locations, backup OSCCAL location and the
Configuration Word.

Note 1: In the PIC12F519, the programming high voltage is internally generated. To activate the Program/Verify
mode, high voltage of I
IHH current capability (see Table 6-1) needs to be applied to the MCLR input.
