PIC16C6XX/7XX/9XX
This document includes the
programming specifications for the
following devices:
1.0 PROGRAMMING THE
PIC16C6XX/7XX/9XX
The PIC16C6XX/7XX/9XX family can be programmed
using a serial method. In Serial mode, the
PIC16C6XX/7XX/9XX can be programmed while in the
users system. This allows for increased design flexibil-
ity. This programming specification applies to
PIC16C6XX/7XX/9XX devices in all packages.
1.1 Hardware Requirements
The PIC16C6XX/7XX/9XX requires two programmable
power supplies, one for V
DD (2.0V to 6.5V recom-
mended) and one for V
PP (12V to 14V). Both supplies
should have a minimum resolution of 0.25V.
1.2 Programming Mode
The Programming mode for the PIC16C6XX/7XX/9XX
allows programming of user program memory, special
locations used for ID, and the configuration word for the
PIC16C6XX/7XX/9XX.
