ATTINY 461-20 PU – MCU, ATTiny AVR RISC, 4 KB, 20 MHz, DIL-20

The ATtiny261/461/861 is a low-power CMOS 8-bi t microcontroller based on the AVR enhanced RISC architecture. By executing powerful in structions in a single clock cycle, the ATtiny261/461/861 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consum ption versus processing speed. The AVR core combines a rich instruction set wit h 32 general purpose working registers. All the 32 registers are directly connected to the Arit hmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achiev ing throughputs up to ten times faster than con- ventional CISC microcontrollers.
