ATtiny85-20PU

Overview
The ATtiny25/45/85 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. Byexecuting powerful instructions in a single clock cycle, the ATtiny25/45/85 achieves throughputs approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
