Abstract: An apparatus and methods are disclosed for a bidirectional front-end circuit included within a system on chip (SoC). The bidirectional front-end circuit includes a differential bidirectional terminal for receiving and transmitting signals. The bidirectional front-end circuit is configured to provide a first communication path between a first controller and a connector through the differential bidirectional terminal when operating in a first mode. And, the bidirectional front-end circuit is reconfigured to provide a second communication path between a second controller and the connector through the differential bidirectional terminal when operating in a second mode.

Abstract: Systems and methods for conserving power in a universal serial bus (USB) are disclosed. In one aspect, when a USB device enters a low power mode (e.g., U1 or U2), a clock associated with the USB device is modified to also enter a low power mode. Since the PIPE interface associated with the USB device still requires a clock signal, the low power clock mode must still be able to provide the PIPE interface with a clock signal. However, the clock signal to the PIPE interface does not need to be the same frequency or accuracy as the clock signal used by the USB interface. The modification to the clock changes the clock frequency to a low frequency compared to the normal clock frequency. By using a low frequency clock for the PIPE interface, power is conserved while preserving the functionality of the PIPE interface.

Abstract: Device identification generation in electronic devices to allow external control, such as selection or reprogramming, of device identification for bus communications identification, is disclosed. In this manner, device identifications of electronic devices coupled to a common communications bus in a system can be selected or reprogrammed to ensure they are unique to avoid bus communications collisions. In certain aspects, to select or reprogram a device identification in an electronic device, an external source can be electrically coupled to the electronic device. The external source closes a circuit with a device identification generation circuit in the electronic device. The closed circuit provides a desired electrical characteristic detectable by the device identification generation circuit. The device identification generation circuit is configured to generate a device identification as a function of the detected electrical characteristics of the closed circuit from the external source.

Abstract: Dynamic predictive wake-up techniques are disclosed. A central processing unit (CPU) may initiate an input/output (I/O) transfer. The CPU may ascertain if a predicted time for the transfer exceeds an amount of time required to enter and exit a low-power mode and enter the low-power mode after the transfer is initiated. An I/O controller may calculate how long the transfer will take and compare that calculation to a known exit latency associated with the CPU. The calculated value is decremented by the amount of the known exit latency and the I/O controller may generate an early wake command at the decremented value. The CPU receives the early wake command and wakes such that the CPU is awake and ready to process data at conclusion of the transfer.

Abstract: Enhanced communications over a Universal Serial Bus (USB) Type-C cable are disclosed. In one aspect, a link control circuit is provided in a USB host to enable one or more communication circuits in the USB host to transmit and receive protocol-specific data over a sideband use (SBU) interface according to communication protocols that may or may not be USB compliant. In another aspect, the link control circuit is provided in a USB client to enable one or more communication circuits in the USB client to transmit and receive protocol-specific data over the SBU interface according to communication protocols that may or may not be USB compliant. By configuring the USB host and the USB client to support multi-protocol communications via the SBU interface, it is possible to enable more flexible architectural design in mobile communication devices for enhanced performance and reduced costs.

Abstract: Systems and methods for low voltage secure digital (SD) interfaces are disclosed. Embodiments of the present disclosure relate to systems and voltage for a lower voltage SD or SD Input/Output (SDIO) interface such as two integrated circuits. In particular, a SD or SDIO interface may be established between two SD compliant devices. While the SD compliant devices may otherwise comply with the SD standard, the voltage levels for signals passed between the SD compliant devices may be below 1.8 volts that the standard mandates. This reduced voltage is possible because the distances involved for interchip communication or the short distances involved for mobile terminal to peripheral connection are short enough that the reduced voltage is sufficient to still provide the desired signal strength at the receiver.
