Frequently asked questions
Can I reprogram it multiple times?
No. The PIC12C series is one-time programmable (OTP), so the code cannot be erased and rewritten. For projects that need reprogramming, choose a flash-based part from the same family.
How many pins are available for I/O?
The part provides 6 I/O pins. The remaining pins of the 8-pin package are used for supply, ground and the oscillator/reset functions.
