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.
