The "Mega" AVR chips have a lot of curb appeal (datasheet appeal?), but none of my online parts search engines seem to be able to interpret "ATmegaXXX" as a part number.
Can anyone tell me:
1) If the "mega" devices have a conventional part number I should be using (the ATMEL datasheets' "Ordering Information" section shows only the "MegaXXX" nomenclature
2) Where I can buy these things (esp. Mega 163 in PDIP package) in small qty.
