The ATmega8 is an upgrade path for AT90S/LS4433. One of the most interresting aspects is the small size of the MLF package; beeing only 5x5mm gives this device a very high performance in a small package. Adding the fact that this device can run at 16MHz really makes this a very interresting device! This device is also available in a 3V version, ATmega8L
