In-Circuit Serial 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
In 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 ICSPCLK pin is the clock input. For more infor-
mation on ICSP™ refer to the “PIC16F/LF1826/27
Memory Programming Specification” (DS41390)
27.1
The device is placed into high-voltage Program/Verify
mode by holding the ICSPCLK and ICSPDAT pins low
then raising the voltage on MCLR/V
