Can someone please tell me (or help me find out) the technology node (1.2, 0.9, 0.7, 0.5, 0.4 or 0.25 micron) used for fabricating the following PIC microcontrollers: PIC16F1829, PIC16F687 and PIC18F14K22. I could not find that information on the microchip website and not much info on it on the web. Thank you in advance
