  • Micro-controller chip and access method thereof
    Patent number: 12314190
    Abstract: A micro-controller chip is coupled to an external memory and includes a central processing unit (CPU), an address reorder circuit, and an address bus. The CPU is configured to provide a first internal address. The address reorder circuit calculates a unique identifier and a seed code to generate a base parameter and performs a reorder operation for the first internal address according to the base parameter to generate a first encryption address. The address bus is coupled between the address reorder circuit and the external memory to provide the first encryption address to the external memory. The external memory stores specific data according to the first encryption address.

  • Communication system, master device, and communication method
    Patent number: 9094357
    Abstract: A communication system, a master device, and a communication method are provided. The communication system includes a master device and at least one slave device. The master device periodically sends a plurality of synchronous messages at intervals of a first predetermined time. The at least one slave device respectively receives the corresponding synchronous messages via wireless communication. The master device and the at least one slave device synchronously switch an operating frequency of wireless communication according to a frequency table.
