2. Overview
The Atmel® ATtiny1634 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 Atmel ATtiny1634 achieves throughputs approaching 1MIPS per
MHz allowing the system designer to optimize power consumption versus processing speed.
