DSPIC304F13 MICROCONTROLADOR 16 BITS 40 PINES

Microcontrolador avanzado de señal digital flash mejorados dsPIC30F de 16 bits

Un dspic es un procesador de señal digital y me permite realizar operaciones de multiplicación , división , resta, suma , en un solo ciclo de reloj , por cuanto internamente posee implementado el hardware para dichas operaciones, me permite trabajar con puntos flotantes, se pueden emplear para filtrado de señales , control de posicionamiento de motores, pude funcionar a una velocidad máxima de 120 Mhz, por ende se puede emplear en telecomunicaciones, son un adelanto a los PICs ( que trabajan con 8 bits).
