ATMEGA128A - AU Microcontroller - (SMD TQFP Package) - 8-Bit 64 Pin 128K Flash Microcontroller

The ATmega128A is an 8-bit CMOS microcontroller with a low power consumption based on the AVR improved RISC architecture. The ATmega128A delivers throughputs approaching 1 MIPS per MHz by executing strong instructions in a single clock cycle, allowing the system designer to optimize power consumption versus processing performance. The AVR core has 32 general-purpose working registers and a large instruction set. The Arithmetic Logic Unit (ALU) is directly coupled to all 32 registers, allowing two independent registers to be accessed in a single instruction executed in one clock cycle. The resulting architecture is more code efficient than traditional CISC microcontrollers, with throughputs up to ten times faster.
