ATTINY406-SN

The ATtiny406 is a member of the tinyAVR 0-series of microcontrollers, using the AVR processor with hardware multiplier, running at up to 20 MHz, with 4 KB Flash, 256 bytes of SRAM, and 128 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.
