Microcontrollers from Microchip for low power, embedded security applications

Microchip’s 16-bit, PIC24 MCUs and dsPIC® Digital Signal Controllers provide designers with an easy upgrade path from 8-bit PIC® microcontrollers and a cost effective option to 32-bit MCUs. The broad product line includes everything from eXtreme Low Power microcontrollers to high performance digital signal controllers. With single cycle execution, deterministic interrupt response, zero overhead looping, and fast DMA, the dsPIC family also adds a single cycle 16×16 MAC and 40-bit accumulators, ideal for math intensive applications like motor control and digital power.

Combined with hardware and free software, these 16-bit products are ideal for designs including high efficiency Motor Control, platinum-rated Digital Power Supplies, and Low Power for longer battery life in portable applications. Integrated touch and display features help lower costs and simplify designs for user interfaces including mTouch® Sensing, Graphics, and Segmented Display drivers. Also specialized peripherals and software for Connectivity such as USB, CAN and wireless protocols make it easy to communicate with other systems.
