Overview

2467XS–AVR–06/11

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

package should be soldered to ground.

The Atmel® AVR® 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 1MIPS per MHz allowing the system designer to

optimize power consumption versus processing speed.
