ATTINY814-SSNR Microchip

ATtiny214/414/814 AVR Microcontroller with Core Independent Peripherals and picoPower Technology Introduction The ATtiny214/414/814 microcontrollers are using the high-performance low-power AVR RISC architecture, and is capable of running at up to 20MHz, with up to 2/4/8KB Flash, 128/256/512bytes of SRAM and 64/128bytes of EEPROM in a 14- pin package. The 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 driven shield are supported with the integrated QTouch peripheral touch controller.
