ATtiny1617/3217, tinyAVR® 1-series Preliminary Datasheet

PublishTime：2021-12-28

●Introduction
■The ATtiny1617/3217 are members of the tinyAVR® 1-series of microcontrollers, using the AVR® processor with hardware multiplier, running at up to 20 MHz, with 16/32 KB Flash, 2 KB of SRAM, and 256 bytes of EEPROM in a 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.
