On ATmega88 AVR, there is a pin called TH. standing for thermal. What is it for? I could not find any information about it in datasheet. Thanks smdfan

I can’t find it. What is the pin number?

TheDirty: I’m assuming this is what someone labeled the pad on the QFN and MLF parts, which should be grounded. From EAGLE’s schematics, the pin is labeled as TH (Thermal). On board layout there is not extra pin labeled as TH but underneath the IC, there is an area. I am not sure if this area i…

That pad is grounded, on most QFN chips.

leon_heller: That pad is grounded, on most QFN chips. It is not QFN but TQFP type of IC. Thanks

I don’t think that any AVR in TQFP has a pad. What is the part number?

what is TH. pin?
