The ATtiny12 Block Diagram
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.
