Definition: The ATmega328C microcontroller is an Intel-based microcontroller designed for embedded systems, enabling hardware/software integration into digital circuits, particularly in a microcontroller that provides full 16-bit floating-point support with 4096-bit registers. ATmega328C defines "Atmel" as its product name and is the primary device used to drive ATmega328E microcontrollers. The ATmega328C family includes a wide variety of devices, such as ATmega168, ATmega328E, ATmega5400, ATmega1600 series, and more.
