Security ICs

Microchip Technology Security ICs ensure trust for every system design. Flexibility, advanced features, innovative, cost-effective architectures, and ultra-secure hardware defense mechanisms make Microchip hardware-based security devices an ideal way to add trust by design at scale. Typical uses include IoT cloud authentication, automotive security, accessory authentication, counterfeit protection, IP protection, and firmware validation.
