    • A microcontroller unit (MCU) is disclosed with a stand-alone Real Time Clock (RTC). The MCU includes a processing circuit for receiving digital information and processing said received digital information. A primary clock circuit provides the timing for the processing circuit. A power control circuit controls the power to the processing circuit and the primary clock circuit to control the operation thereof to operate in at least a full power mode drawing a full power level from a supply voltage input and a reduced power mode drawing less than the full power level from the supply voltage input. A stand-alone RTC circuit is also provided, the stand­alone RTC circuit including an RTC clock circuit operating independent of the primary clock circuit. A timer clocked by the RTC clock circuit is operable to increment a stored time value for output therefrom, the RTC clock circuit having a defined time base. An input/output (I/O) device provides access by the processing circuit to the results output by the timer. A power management circuitry manages the power to the stand-alone RTC circuit, such that the RTC clock circuit, the timer, and the I/O device operate regardless of the power mode of operation of the processing circuitry and the primary clock circuit.
    • 具有独立实时时钟(RTC)的微控制器单元(MCU)被公开。 MCU包括用于接收数字信息并处理所述接收到的数字信息的处理电路。 主时钟电路为处理电路提供时序。 功率控制电路控制处理电路和主时钟电路的功率,以控制其操作以至少全功率模式工作,从电源电压输入中抽取全功率电平,并且抽取小于满的功率模式 来自电源电压输入的功率电平。 独立的RTC电路也是独立的RTC电路,包括一个独立于主时钟电路工作的RTC时钟电路。 由RTC时钟电路计时的计时器可操作以递增所存储的时间值以供其输出,RTC时钟电路具有限定的时基。 输入/输出(I / O)设备提供处理电路对定时器输出的结果的访问。 电源管理电路管理独立RTC电路的电源,使得RTC时钟电路,定时器和I / O设备操作,而与处理电路和主时钟电路的电源操作模式无关。 / p>

    • A portable media encoder is disclosed. The portable media encoder comprises a video input port configured to receive a video input from a video source, an audio input port configured to receive an audio input from an audio source, and a digital output port for providing a digitized output stream corresponding to the received video input and audio input. The encoder has an encoding processor that converts the video input and the audio input into a streamable digital output format for transmitting through the digital output port, a set of control buttons communicatively coupled to the encoding processor and operable to provide encoding parameters to thereto, and a housing enclosing the encoding processor and providing at least one access panel providing user access to the video input port, the audio input port, the digital output port, and the set of control buttons. The housing having a size and configuration that allows the encoder to be hand carried by a single individual.
