3.2 Overview
The embedded core is an extremely low-power CMOS 8-bit microcontroller based on the AVR
enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the AVR
core achieves throughputs approaching 1 MIPS per MHz allowing the designer to optimize
power consumption versus processing speed.
