In some implementations, a microcontroller system comprises a system bus and a secure central processing unit (CPU) coupled to the system bus. The secure CPU is configured to provide secure access to the system bus. A non-secure CPU is also coupled to the system bus and is configured to provide non-secure access to the system bus. A non-secure memory is coupled to the system bus and is configured to allow the secure CPU and the non-secure CPU to exchange data and communicate with each other. A peripheral access controller (PAC) is coupled to the system bus and configured to enable secure access to a peripheral by the secure CPU while disabling non-secure access to the peripheral based upon a non-secure state of the non-secure CPU."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure access in a microcontroller system","description":"Systems, methods and computer-readable mediums are disclosed for providing secure access in a microcontroller system.
