Pin 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 sys-

tem designer to optimize power consumption versus processing speed.
