Availability: In production

Deviceimage

Summary

The ATmega128 is the absolute killer AVR!! It is a natural upgrade path for the ATmega103 AVR with a lot of added goodies. This device runs at 16MHz! Among the many new/improved fetaures are JTAG interface with On Chip Debugging possibilities, USART, 2-wire interface (compatible with I2C devices) Internal RC osc, self programming .. This device has it all! The ATmega128 is also available in a 3V version; ATmega128L

Crossrelation

  • shrink upgrade path of mega103
  • pin compatible with mega103, more features.
  • pin compatible with mega169, less features.
  • pin and feature compatible with mega64, more memory.
