The ATMEGA128A-AU is designed as one kind of low-power CMOS 8-bit microcontroller that achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. This device is manufactured using Atmel's high-density nonvolatile memory technology, and is supported with a full suite of program and system development tools including: C compilers, macro assemblers, program debugger / simulators, in-circuit emulators, and evaluation kits.

Features of the ATMEGA128A-AU are:(1)high-performance, low-power 8-bit microcontroller;(2)133 powerful instructions - most single clock cycle execution;(3)32 x 8 general purpose working registers + peripheral control registers;(4)up to 16 MIPS throughput at 16 MHz;(5)128K bytes of in-system self-programmable flash program memory;(6)write/erase cycles: 10,000 flash/100,000 EEPROM;(7)up to 64K bytes optional external memory space;(8)programming lock for software security;(9)SPI interface for in-system programming;(10)two 8-bit timer/counters with separate prescalers and compare modes;(11)6 PWM channels with programmable resolution from 2 to 16 bits;(12)real time counter with separate oscillator;(13)output compare modulator.
