PIC12F629/675/PIC16F630/676
This document includes the
programming specifications for the
following devices:
1.0 PROGRAMMING THE
PIC12F629/675/PIC16F630/676
The PIC12F629/675/PIC16F630/676 is programmed
using a serial method. The Serial mode will allow the
PIC12F629/675/PIC16F630/676 to be programmed
while in the user’s system. This allows for increased
design flexibility. This programming specification
applies to PIC12F629/675/PIC16F630/676 devices in
all packages.
1.1 Hardware Requirements
The PIC12F629/675/PIC16F630/676 requires one
power supply for V
DD (5.0V) and one for VPP (12V).
1.2 Programming Mode
The Programming mode for the PIC12F629/675/
PIC16F630/676 allows programming of user program
memory, data memory, special locations used for ID
and the Configuration Word register.
