ATtiny1614/1616/1617 Automotive tinyAVR 1-series Introduction The ATtiny1614/1616/1617 Automotive are members of the tinyAVR 1-series of microcontrollers, using the AVR processor with hardware multiplier, running at up to 16 MHz, with 16 KB Flash, 2 KB of SRAM, and 256 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.
