PIC12C67X AND PIC12CE67X
This document includes the programming
specifications for the following devices:
PIC12C671
PIC12C672
PIC12CE673
PIC12CE674
1.0
PROGRAMMING THE
PIC12C67X AND PIC12CE67X
The PIC12C67X and PIC12CE67X can be pro-
grammed using a serial method. In serial mode the
PIC12C67X and PIC12CE67X can be programmed
while in the users system. This allows for increased
design flexibility.
1.1
Hardware Requirements
The PIC12C67X and PIC12CE67X requires two pro-
grammable power supplies, one for V
recommended) and one for V
supplies should have a minimum resolution of 0.25V.
DD
(2.0V to 6.0V
PP
(12V to 14V). Both
1.2
Programming Mode
The programming mode for the PIC12C67X and
PIC12CE67X allows programming of user program
memory, special locations used for ID, and the configu-
ration word for the PIC12C67X and PIC12CE67X.
