Abstract: An apparatus for remote wake-up during dedicated charging mode includes: a USB transceiver port; a USB connector port; a switch network coupling the USB transceiver port to the USB connector port; and control logic coupled to the switch network and operative to control the switch network to disconnect the USB transceiver port from the USB connector port during a dedicated charger operational mode and to connect the USB transceiver port to the USB connector port upon the detection of a potential remote wake-up condition.

Abstract: In an embodiment, set forth by way of example and not limitation, a USB dedicated charger identification circuit includes a USB D+ port, a USB D? port, a first circuit conforming to a first identification protocol, a second circuit conforming to a second identification protocol, and logic selectively coupling one of the first circuit and the second circuit to the USB D+ port and the USB D? port. In an alternate embodiment set forth by way of example and not limitation, a method to provide USB charger identification includes providing a first USB charger identification at a USB D+ port and a D? port, Next, it is detected if the first USB charger identification was inappropriate. Then, if the first USB charger identification was inappropriate, a second USB charger identification is provided at the USB D+ port and the D? port.

Abstract: Methods and apparatus for adding an autonomous controller to an existing architecture such as by way of example, portable devices such as cell phones, MP3 players, and digital cameras. A circuit interposed between the memory card and the system controller of the device is controllable to couple the memory card to the system controller, or to couple the memory card to a high speed I/O controller on the circuit. When the memory card is coupled to the high speed I/O controller on the circuit, the circuit provides signals to the system controller indicative of a memory card removal event. In systems having an I/O connection such as a USB connection, the circuit also disconnects that connection from the system controller, provides signals to the system control indicative of a USB disconnect and connects the I/O connection to the memory card through a high speed data transfer unit to provide a higher speed I/O capability. Various features and capabilities are disclosed.
