ATtiny11/12
Figure 2 on page 4. 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 regis-
ters, 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 con-
tinue 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 ATtiny12 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 ATtiny12 is
a powerful microcontroller that provides a highly-flexible and cost-effective solution to
many embedded control applications.
