AVR 8-bit Microcontrollers
ATtiny417 / ATtiny814 / ATtiny816 / ATtiny817
DATASHEET PRELIMINARY
Introduction
The Atmel® ATtiny417/814/816/817 microcontrollers are using the 8-bit AVR®
processor with hardware multiplier, running at up to 20MHz, with up to 4/8KB
Flash, 256/512 bytes of SRAM and 128 bytes of EEPROM in a 14-, 20- or
24-pin package. The series uses the latest technologies from Atmel 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.
