ATtiny416/417/814/816/817
Automotive
tinyAVR
®
1-series
Introduction
The ATtiny416/417/814/816/817 Automotive are members of the tinyAVR
®
1-series of microcontrollers,
using the AVR
®
processor with hardware multiplier, running at up to 16 MHz, with 4/8 KB Flash, 256/512
bytes of SRAM, and 128 bytes of EEPROM in a 14-, 20- or 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.
