MICROCHIP ATTINY404-SSF

The ATtiny204/404 are members of the tinyAVR 0- series of microcontrollers, using the AVR processor with hardware multiplier, running at up to 20 MHz, with 2/4 KB Flash, 128/256 bytes of SRAM, and 64/128 bytes of EEPROM in a 14- 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.
