I intend to have a microcontroller in my LM3886 audio amp used for general housekeeping and a digital pot volume control. To program this PIC microcontroller, there are five pins needed: 5V power, ground, 13V programming voltage, data, and clock.
Many designs that use a microcontroller have the uC programming port inside the enclosure on the PC circuit board. I want to have mine connected to the enclosure, accessible from the back. The idea is that when I want to reprogram the microcontroller, I won't have to take the case apart - I can simply plug my PIC programmer into the programming port on the back.
Being that the port will now be "exposed" to the outside world, should I put in any extra protection circuitry at the programming port to protect the microcontroller from things like static electricity?
