Hello fellow freaks!

Just so that I understand it all correct. Looking at the PDF for example ATtiny44 or 45, the MLF20 version. Is it really 0.5 mm between each pin? (e measurment). It says 0.50 BSC, dunno what BSC is.

The reason I ask is that in every library file in eagle it's 0.025 inchs instead ( = 0.635 mm).

Is every library file wrong, or can't I just don't read a simple datasheet? :?

BSC = Basic Spacing between Centers. Can also mean BASIC which is just another way of saying 'nominal'.

Yes, 0.50 in the case of attiny45 etc is 0.50mm pin spacing
