  • Patent number: 9429468
    Abstract: In an exemplary embodiment, an apparatus includes a sensor integrated circuit (IC) that is adapted for ambient light sensing (ALS) and/or proximity detection. The sensor integrated circuit (IC) includes an integrated analog-to-digital converter (ADC) that is adapted to convert at least one signal related to ambient light sensing (ALS) and/or proximity detection to at least one digital signal, and an integrated light emitting diode (LED) driver that is adapted to drive at least one LED. The sensor IC also includes an integrated power management unit (PMU) that is adapted to reduce power dissipation of the sensor IC by running at a low duty cycle the integrated LED driver and the integrated ADC.

  • Publication number: 20120054379
    Abstract: An integrated control circuit is disclosed including a central processing unit operating in a normal full system power mode and in a reduced system low power mode, and a memory. A plurality of peripheral units are provided, at least one of which includes an input/output for interfacing with at least an external system for receiving information therefrom and a process block. The process block processes the received information from the external system and during the processing of the received information, data is stored in the at least one peripheral unit, and data is transferred at least to or at least from the memory. The input/output and process blocks are fully operable in the full system power mode and the reduced system power mode. A direct memory access (DMA) transfers data directly between the at least one peripheral and the memory when such data transfer is required by the peripheral.
