Microchip Technology Periféricos independentes do núcleo Microchip Technology

Os microcontroladores PIC Microchip Technology com periféricos independentes do núcleo permitem que os designers elevem o desempenho do MCU de 8 bits a um novo patamar. A oferta inclui um número de módulos na placa, projetados para o aumento de capacidade em qualquer sistema de controle e para fornecer uma impressionante eficiência incorporada ao projeto. Os periféricos independentes do núcleo gerenciam suas tarefas sem nenhum código ou supervisão da CPU para manter a operação. Como resultado, eles simplificam a implementação de um sistema de controle complexo e permite aos desenvolvedores a flexibilidade de inovar.
