Connected (Wired & Wireless)

Microchip Technology Connectivity is easy to add to applications, as Microchip's MCUs and MPUs are designed to be compatible with Microchip wired and wireless devices. Robust, reliable, high-speed connectivity is available with a broad portfolio of wired connectivity solutions. Mobility, convenience, and enhanced user experience are possible with a wide range of wireless connectivity solutions. And, with pre-certified modules, designers can avoid worrying about communication regulations.‌
