This family expands on the existing line of Microchip‘s 16-bit general purpose microcontrollers, combining enhanced computational performance with an expanded and highly configurable peripheral feature set. The PIC24FJ256GA110 family provides a new platform for high-performance applications, which have outgrown their 8-bit platforms, but don’t require the power of a digital signal processor.
