This document describes an 8-bit microcontroller that utilizes the AVR RISC architecture and offers high performance and low power consumption. It features nonvolatile program and data memory, as well as various peripheral features. Additionally, it includes special microcontroller features and specifications, such as low-power modes and interrupt sources.
The ATtiny11 and ATtiny12 are low‑power CMOS 8‑bit microcontrollers based on Atmel's AVR® RISC architecture. They deliver up to 1 MIPS per MHz and include 32 general‑purpose working registers, an 8‑bit timer/counter, an on‑chip analog comparator, and programmable watchdog timer.
Key features include 1 KB of flash program memory, up to 64 B of EEPROM (ATtiny12), multiple power‑saving modes, and operating voltage ranges from 1.8 V to 5.5 V. The devices are offered in 8‑pin PDIP and SOIC packages and are intended for cost‑effective embedded control applications.
