Der ATmega128 wird im Roboterbausatz NIBO 2 als Hauptprozessor eingesetzt. Es handelt sich hierbei um einen 8-Bit AVR Mikrocontroller von Atmel mit 128 kByte Flash-Speicher. Da es sich um ein SMD (surface-mounted device) Bauteil handelt, ist der Mikrocontroller im Bausatz bereits auf der Platine aufgelötet.
Technische Daten
| ATmega128 | ATmega128L | |
| FLASH(kBytes) | 128 | 128 |
| EEPROM(kBytes) | 4 | 4 |
| SRAM(kBytes) | 4 | 4 |
| Freq(MHz) | 16 | 8 |
| Spannung(V) | 4,5 - 5,5 | 2,7 - 5,5 |
FuseBits
Die einzelnen Fuse-Bits sind logisch invertiert: 1 (unprogrammed) bedeutet inaktiv, 0 (programmed) beudeutet aktiv.
Beispiel: Der Kompatibiltätsmodus zum veralteten ATmega103 ist aktiv wenn das Bit M103C den Wert 0 hat!
