ATtiny417/817

AVR® Microcontroller with Core Independent Peripherals

and picoPower® Technology

Introduction

The ATtiny417/817 microcontrollers are using the high-performance low-power AVR

RISC architecture,

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

of EEPROM in a 24-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.
