ATMEGA32U4-MU

8位微控制器 -MCU AVR USB 32K FLASH INDUSTRIAL

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

Overview ATMEGA32U4-MU

The ATMEGA32U4-MU ATmega16U4/ATmega32U4 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 device achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
