Overview
The ATmega169 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 ATmega169 achieves
throughputs approaching 1 MIPS per MHz allowing the system designer
to optimize power consumption versus processing speed.
