2. Overview
The AT90USB82/162 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By exe-
cuting powerful instructions in a single clock cycle, the AT90USB82/162 achieves throughputs approaching 1 MIPS per
MHz allowing the system designer to optimize power consumption versus processing speed.

The AVR core combines a rich instruction set with 32 general purpose working registers. All the
32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent
registers to be accessed in one single instruction executed in one clock cycle. The resulting
