ATmega16A [DATASHEET]
Atmel-8154C-8-bit-AVR-ATmega16A_Datasheet-07/2014
2. Overview
The ATmega16A is a low-power CMOS 8-bit microcontroller based on the Atmel
AVR enhanced RISC
architecture. By executing powerful instructions in a single clock cycle, the ATmega16A achieves throughputs
approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing
speed.
