ATtiny212
Overview
The ATtiny212/214/412/414/416 are members of the tinyAVR®1-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 8-, 14-, and 20-pin package. The tinyAVR®1-series uses the latest technologies with a flexible, lowpower architecture, including Event System, accurate analog features, and Core Independent Peripherals (CIPs).
