PIC16C50X
This document includes the programming
specifications for the following devices:
1.0 PROGRAMMING THE
PIC16C50X
The PIC16C50X can be programmed using a serial
method. Due to this serial programming, the
PIC16C50X can be programmed while in the user’s
system, increasing design flexibility. This programming
specification applies to PIC16C50X devices in all
packages.
1.1 Hardware Requirements
The PIC16C50X requires two programmable power
supplies, one for V
DD (2.0V to 6.5V recommended) 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 PIC16C50X allows
programming of user program memory, and the config-
uration word for the PIC16C50X.
