ATtiny11 Block Diagram

See Figure 1 on page 3. The ATtiny11 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 Watch-

dog Timer with internal oscillator, and two software-selectable power-saving modes.

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.
