This chip doesn't natively support USB. You want chips with USB in the name or ending in U2, U4 or U6.
AmMega is a different company to Atmel. I don't know what this chip does, but it's almost certainly no use...
you mean we built nothing ?? are you saying that the board we built is useless and the chip will not work ? the board that we built is atmega16 not 164 and datasheet is same for both so if 164 will work then 16 should work too !
please don't tell me i was working for nothing ! anybody can help ? the chip needs to be programmed by a programmer i use isp port for programming.
