ICSP™ programming allows customers to manufacture
circuit boards with unprogrammed devices. Programming
can be done after the assembly process allowing the
device to be programmed with the most recent firmware
or a custom firmware. Five pins are needed for ICSP™
programming:
• ICSPCLK
• ICSPDAT
• MCLR/V
• V
• V

The device is placed into Program/Verify mode by
holding the ICSPCLK and ICSPDAT pins low then
raising the voltage on MCLR/V
Program/Verify mode the Program Memory, User IDs
and the Configuration Words are programmed through
serial communications. The ICSPDAT pin is a
bidirectional I/O used for transferring the serial data and
the ISCPCLK pin is the clock input. For more information
on ICSP™ refer to the “PIC16F72x/PIC16LF72x
Programming Specification” (DS41332).

The ICD 2 produces a V
than the maximum V
PIC16F72X/PIC16LF72X. When using
this programmer, an external circuit, such
as the AC164112 MPLAB ICD 2 V
age limiter, is required to keep the V
voltage within the device specifications.
