MICROCHIP ATTINY214-SSN

The ATtiny212/214/412/414 Automotive are members of the tinyAVR 1- series of microcontrollers, using the AVR processor with hardware multiplier, running at up to 16 MHz, with 2/4 KB Flash, 128/256 bytes of SRAM, and 64/128 bytes of EEPROM in a 8- and 14- pin package. The tinyAVR 1- series uses the latest technologies with a flexible, low- power architecture, including Event System, accurate analog features, and Core Independent Peripherals (CIPs).
