8-bit AVR Microcontroller

ATtiny1614 / ATtiny1616 / ATtiny1617

Introduction

The ATtiny1614/1616/1617 is a member of the tinyAVR 1-series of microcontrollers, using the 8-bit AVR

processor with hardware multiplier, running at up to 20MHz and with 16KB Flash, 2KB of SRAM and

256B of EEPROM in a 14-, 20- and 24-pin package. The tinyAVR 1-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 proximity sensing and driven shield

are supported with the integrated QTouch

peripheral touch controller.
