Features & Applications

Microchip provides solutions for the entire performance range of 8-bit, 16-bit, and 32-bit microcontrollers, with a powerful architecture, flexible memory technologies, comprehensive easy-to-use development tools, complete technical documentation and post design-in support through a global sales and distribution network.16-bit PIC Microcontrollers & dsPIC Digital Signal Controllers. Microchip offers two 16-bit Microcontroller (MCU) families plus two 16-bit Digital Signal Controller (DSC) families that give you compatible options across a wide spectrum of price, performance and feature sets.

Common attributes among all 16-bit MCU and DSC families are pinouts, software, peripherals and development tools. Whether your design requires the lowest-priced 16-bit solution, the most powerful 16-bit MCU in the industry,or DSP capability, Microchip offers a broad range of products while preserving the compatibility that help save you time and money on subsequent designs.
