    What is ATMEGA16U2-MU?

    ATMEGA16U2-MU is a CMOS 8-bit microcontroller based on 16KB of ISP flash program memory and USB controller including 22 I/O ports. 16MHz reference frequency is used to operate the AVR core processor. By allowing the system designer to provide optimization to processing speed and power consumption, the ATmega16U2 achieves throughputs approaching 1 MIPS per MHz by implementing powerful instructions in a single clock cycle.

    ATMEGA16U2-MU is designed and manufactured with Atmel’s nonvolatile high-density memory technology. The ISP flash in chip let the program to be reprogrammed in-system by using SPI serial interface. the Atmel ATmega16U2 is a well built powerful microcontroller that offers a highly flexible and cost-effective solution to many embedded control applications by merging In-System Self-Programmable Flash with 8-bit RISC CPU on a monolithic chip.

    The ATmega16U2 is supported with a full suite of program and system development tools including in-circuit emulators, C compilers, evaluation kits, macro assemblers,  and program debugger/simulators.
