8-Bit MCUs

8-bit PIC® and AVR® Microcontrollers 

Effortless Design

PIC and AVR microcontrollers (MCUs) help you to easily bring your ideas to life, no matter your skill level. Pick from our broad portfolio of uniquely configurable MCUs and start designing quickly using our award-winning integrated development environments with production-ready code generation tools and best-in-class rapid prototyping hardware. This complete offering of silicon, development environments and industry knowledge enables you to easily add functionality and robustness to your designs while shortening the overall design cycle. Our commitment to long-term availability of PIC and AVR MCUs ensures that you can continue using your existing parts or easily migrate to other fully compatible device family members to increase functionality without requiring an extensive redesign.
