Note:
The Atmel
enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the
ATmega128A achieves throughputs approaching 1MIPS per MHz allowing the system designer
to optimize power consumption versus processing speed.

The Pinout figure applies to both TQFP and MLF packages. The bottom pad under the QFN/MLF
package should be soldered to ground.
