ATtiny214/414/814

AVR® Microcontroller with Core Independent Peripherals

and picoPower® Technology

Introduction

The ATtiny214/414/814 microcontrollers are using the high-performance low-power AVR

RISC

architecture, and is capable of running at up to 20MHz, with up to 2/4/8KB Flash, 128/256/512bytes of

SRAM and 64/128bytes of EEPROM in a 14- pin package. The series uses the latest technologies with a

flexible and low power architecture including Event System and SleepWalking, accurate analog features

and advanced peripherals. Capacitive touch interfaces with driven shield are supported with the

integrated QTouch

peripheral touch controller.
