The ATtiny12 provides the following features: 1K bytes of Flash, 64 bytes EEPROM, up

to six general-purpose I/O lines, 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 allowing the timer/counters and interrupt system to continue func-

tioning. 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 ATtiny12 to be highly responsive to exter-

nal 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 ATtiny12 is

a powerful microcontroller that provides a highly-flexible and cost-effective solution to

many embedded control applications.
