Hi, I am also going to migrate from 16F877A to 18F4620 in a near future. I have seen some lock-ups and resets on the 877A due to ESD (it is extremely dry here), I have ESD protection on all connectors but the spike still resets the PIC. Would you please share your successful bypassing with me and others.

How did you connect MCLR?

How many caps and what kind/size do you recommend using to bypass VDD to the pic?

All help is greatly appreciated!
