Overview
Block Diagram
2466TS–AVR–07/10
The ATmega16 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC
architecture. By executing powerful instructions in a single clock cycle, the ATmega16 achieves
throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power con-
sumption versus processing speed.
