1.0 PROGRAMMING THE
PIC16F627A/628A/648A
The PIC16F627A/628A/648A is programmed using a
serial method. The Serial mode will allow the
PIC16F627A/628A/648A to be programmed while in
the user’s system. This allows for increased design
flexibility. This programming specification applies to
PIC16F627A/628A/648A devices in all packages.
1.1 Hardware Requirements
The PIC16F627A/628A/648A requires one program-
mable power supply for V
DD (2.0V to 5.5V) and a VPP
of 12V to 14V, or VPP of 4.5V to 5.5V, when using low
voltage. Both supplies should have a minimum
resolution of 0.25V.
1.2 Programming Mode
The Programming mode for the
PIC16F627A/628A/648A allows programming of user
program memory, data memory, special locations used
for ID, and the Configuration Word.
