Configurations

Figure 1. Pinout ATmega128

Note:

The Pinout figure applies to both TQFP and MLF packages. The bottom pad under the QFN/MLF

package should be soldered to ground.

Overview

The ATmega128 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC

architecture. By executing powerful instructions in a single clock cycle, the ATmega128

achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize

power consumption versus processing speed.
