ATtiny417/817

tinyAVR

1-series

Introduction

The ATtiny417/817 are members of the tinyAVR

1-series of microcontrollers, using the AVR

processor with

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

in a 24-pin package. The tinyAVR

1-series uses the latest technologies with a flexible, low-power architecture

including Event System and SleepWalking, accurate analog features, and Core Independent Peripherals. Capacitive

touch interfaces with driven shield are supported with the integrated QTouch

peripheral touch controller.
