Secure Microcontrollers
Advanced Cryptography Meets Physical Layer Security to Protect Your IP and Digital Assets
Our secure microcontrollers provide ongoing protection for your digital assets and intellectual property (IP) against continuously emerging threats. Our secure MCU ICs employ FIPS-certified, hardware cryptographic engines which support industry-standard algorithms. Advanced cryptography, combined with physical layer security, means that when you select a secure microcontroller from our diverse offering, you are guaranteed the highest level of protection against side-channel attacks, physical tampering, and reverse engineering.
Other notable features of our secure microcontrollers include:
- Integrated secure memory (NV SRAM) that is instantly erased when an intrusion is detected
- Patented real-time code and data encryption that fully protects external memory
- Hardware that conforms to EMV, PCI, and FIPS standards
- Secure boot and ChipDNA™ PUF technology that protect IoT designs against hacker attacks
