By executing powerful instructions in a single clock cycle, the ATtiny11/12 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 architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.

The Idle Mode stops the CPU while allowing the timer/counters and interrupt system to continue functioning. The Power-down Mode saves the register contents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset. The wake-up or interrupt on pin change features enable the ATtiny11 to be highly responsive to external events, still featuring the lowest power consumption while in the power-down modes. The device is manufactured using Atmel’s high-density nonvolatile memory technology. By combining an RISC 8-bit CPU with Flash on a monolithic chip, the Atmel ATtiny11 is a powerful microcontroller that provides a highly-flexible and cost-effective solution to many embedded control applications.
