ATtiny806/1606 tinyAVR 0-series Introduction The ATtiny806/1606 are members of the tinyAVR 0-series of microcontrollers, using the AVR processor with hardware multiplier, running at up to 20 MHz, with 8/16 KB Flash, 512/1024 bytes of SRAM, and 128/256 bytes of EEPROM in a 20-pin package. The tinyAVR 0-series uses the latest technologies with a flexible, low-power architecture including Event System and SleepWalking, accurate analog features, and Core Independent Peripherals. Attention: Automotive products are documented in separate data sheets.
