ATMEGA16U2-MU

8位微控制器 -MCU AVR USB 8K FLASH AVR USB 16K FLASH

8-bit  Microcontroller  with  8/16/32K Bytes  of ISP Flash  and USB  Controller

Overview ATMEGA16U2-MU

The ATMEGA16U2-MU ATmega8U2/16U2/32U2 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega8U2/16U2/32U2 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
