ATtiny AVR 8-bit Microcontrollers

Microchip Technology ATtiny AVR® 8-bit Microcontrollers (MCUs) are optimized for applications that require performance, power efficiency, and ease of use in a small package. The ATtiny417/ATtiny814/ATtiny816/ATtiny817 MCUs offer an 8-bit AVR processor with a hardware multiplier running at up to 20MHz, with up to 8KB Flash, 512 bytes of SRAM, and 128 bytes of EEPROM in 14-pin, 20-pin, and 24-pin packages. These devices use Atmel picoPower® technology to enable a flexible and low power architecture including Event System and SleepWalking, accurate analog features, and advanced peripherals. Capacitive touch interfaces with a driven shield are supported with the integrated QTouch® peripheral touch controller.
