ATMEGA128A-AU Datasheet
Description
The Atmel® ATmega128A is an 8-bit CMOS microcontroller based on the AVR® improved RISC architecture. The ATmega128A achieves throughputs close to 1MIPS per MHz by executing strong instructions in a single clock cycle. The system designer is now able to tune the gadget for power consumption vs processing speed.
