Seriously, don't you wear something that causes you being charged e.g. when walking, and then discharged in the vicinity of the chips? Or isn't there anything close to the place you keep the programmer(s) that emits strong electromagnetic "smog"? Or maybe the mains power carries some strong interference? Something sparking - motors, contactors - working one day and resting another?


Jan,
I suspected ESD also. I discharged all the pins before putting into the programmer. And I am pretty sure that there is no kind of spark emitting stuff in the ambience.

Also about the borrowed chips, they are simply been programmed for twice or thrice. So, I was pretty confident about them also. Anyway, let me figure out if there is any problem with any part other than MCU. Thanks, man.

Regards,
Vignesh.
