ATXMEGA32A4U-MH

8位微控制器 -MCU AVR8 32KB FLSH 4KB

8/16-bit Atmel XMEGA Microcontroller

Overview ATXMEGA32A4U-MH

The ATXMEGA32A4U-MH Atmel AVR XMEGA is a family of low power, high performance, and peripheral rich 8/16-bit microcontrollers based on the AVR enhanced RISC architecture. By executing instructions in a single clock cycle, the AVR XMEGA devices achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus processing speed.
