Scalable Security Solutions With 32-bit MPUs

Security for Low-Power RTOS and Linux® Edge Applications


We build our microprocessors (MPUs) with security as an important function so that you can design a secure solution from the start. We deliver trusted, secure hardware that protects your brand and intellectual property from nefarious actors while delivering secure applications built upon the three pillars of security: confidentiality, integrity and authenticity.

Our SAM MPUs support all aspects of the security you need to bring your applications to market in a secure and cost-effective manner. They include:

  • Secure factory programming solution
  • Secure boot
  • DPA countermeasures
  • Built-in tamper detectors
  • Anti-tamper features (active die shield)
  • True random number generator
  • Dual Physically Unclonable Functions (PUFs)
  • Side channel-resistant crypto accelerators

From basic security implementations all the way up to a segmented processing element known as a secure enclave, SAMA5D2 and SAMA5D4 MPUs provide a wide range of security options to protect your design. Whether you need cloud provisioning, secured communication, certificate management, system resilience, near real-time execution, power management, data security, encryption services, secure boot or secrets storage, we make finding and implementing the right security measures easy.

Create systems quickly and easily that are robust, resistant against bugs, securely field upgradable and that prevent unauthorized software from running and self-curing in the event of a memory content alteration. You now have the power to implement your own secure enclave with the advanced security features in our MPUs, including powerful cryptographic accelerators, secured access to memories and secure peripherals to safeguard system secrets. 

Key Capabilities
