PIC10F220/222
This document includes the
programming specifications for the
following devices:
•PIC10F220
•PIC10F222
1.0 PROGRAMMING THE
PIC10F220/222
The PIC10F220/222 is programmed using a serial
method. The Serial mode will allow the PIC10F220/222
to be programmed while in the user’s system. This
allows for increased design flexibility. This programming
specification applies to PIC10F220/222 devices in all
packages.
1.1 Hardware Requirements
The PIC10F220/222 requires one power supply for
V
DD (5.0V) and one for VPP (12V).
1.2 Program/Verify Mode
The Program/Verify mode for the PIC10F220/222
allows programming of user program memory for user
ID locations, backup OSCCAL location and the
Configuration Word.
