Description
The ATtiny10/11/12 is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing power-
ful instructions in a single clock cycle, the ATtiny10/11/12 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.
ATtiny10/11 Block Diagram
The ATtiny10/11 provides the following features: 1K bytes of Flash, up to five general-purpose I/O lines, one input line,
32 general-purpose working registers, an 8-bit timer/counter, internal and external interrupts, programmable Watchdog
Timer with internal oscillator, and two software-selectable power-saving modes. The Idle Mode stops the CPU while allow-
ing 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 ATtiny10/11 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 ATtiny10/11 is a powerful microcontroller that provides a highly-flexible and cost-
effective solution to many embedded control applications.
The ATtiny10/11 AVR is supported with a full suite of program and system development tools including: macro assemblers,
program debugger/simulators, in-circuit emulators, and evaluation kits.
