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
