8 Bit MCU, Low Power High Performance, AVR ATxmega

8 Bit MCU, Low Power High Performance, AVR ATxmega.

Descrição geral do produto

The Atmel ATXMEGA32A4U-AU is a low power, high performance, and peripheral rich 8 bit microcontroller 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 MHz, allowing the system designer to optimise power consumption versus processing speed. The AVR CPU combines a rich instruction set with 32 general purpose working registers. All 32 registers are directly connected to the arithmetic logic unit (ALU), allowing two independent registers to be accessed in a single instruction, executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs many times faster than conventional single accumulator or CISC based microcontrollers.
