    Abstract: In one embodiment, the invention comprises a flash-media controller used for writing new data from an external system to a local flash-memory device. The newly written data may replace old data previously written to the flash-memory device, and may be written directly to unused locations within the flash-memory device. The flash-media controller may comprise a table of block descriptors and sector descriptors used to track specified characteristics of each block and sector of the flash-memory device, thereby allowing for write sequences to non-contiguous sectors within a block. Accordingly, copy operations may be deferred under the expectation that they will eventually become unnecessary, thereby designating old data as having become stale. Once all data within a block has been designated as being stale, the block may be marked as unused and may be made available for subsequent write operations, thereby providing fast write access to the flash-memory device, and significantly reducing the number of required copy operations during data transfer to the flash-memory device.

    Abstract: A communication system, network, interface, and port architecture are provided for transporting different types of data across a network. The network can be arranged by connecting the ports in a daisy chain fashion to achieve a ring architecture or topology. The network forwards data according to a specific network protocol, and any incoming data that follows that protocol will be sent onto the network. If the incoming data protocol does not match the network protocol, then the incoming data is not sent immediately to the network, but instead is sent to an input pin of a device upon the network specifically designed to receive that incoming data. The network, therefore, has ports that support both compliant and non-compliant incoming data, and the devices that produce such data. Examples of non-compliant data include any data which does not time-division multiplex different asynchronous, isochronous, and synchronous data in dedicated channels within each frame, and which have a preamble, coding, frequency, or overall protocol different from that which is established for network transfer.

    Abstract: System and method for enumerating and/or enumerating a device. The device may be a USB portable device which adheres to a first standard, e.g., the USB specification, and may engage in enumeration with respect to a USB hub/USB host device. Where a battery included in the device is sufficiently low, the device may engage in low power enumeration, e.g., to begin charging the device using enumerated power. Low power enumeration may allow the device to enumerate even when the device is incapable of powering on. Additionally, or alternatively, the device may determine whether the hub/host device is capable of providing high power charging. If it is, the device may begin charging the battery of the device using power provided by the hub/host device at a high power level.

    Abstract: A level-shifter circuit configured to transfer data between two voltage supply domains may eliminate crowbar current while simultaneously providing a valid output signal. The level-shifter circuit may transfer a data signal between the two voltage domains using a latch that is capable of maintaining its output level—based on the destination supply rail—to correspond to the same state to which the level of the input signal—based on the originating supply rail—corresponds, even when the originating supply is decreased to a zero-volt state, or to a voltage equivalent to a low state. During normal operation, when both power supplies are available, the signal at the output of the latch, and hence at the output of the level-shifter circuit may toggle to always track the input signal. Thus, the level of the signal at the output of the level-shifter may always represent the same state (e.g. binary value) as the level of the input signal, during normal operation and also when the originating power supply is powered down.

    Abstract: A power supply management device including a current limiting protection circuit. The power supply management device may include an output terminal, a first transistor, a replication circuit, a comparator circuit, and a control circuit. The first transistor may provide an output current to the output terminal of the power supply management device. The replication circuit may be connected to the first transistor and may replicate the output current to a separate path to monitor the output current. The comparator circuit may be connected to the replication circuit and may compare the replicated output current to a current reference. The control circuit may be connected to the first transistor and to the comparator circuit. In response to the replicated output current being greater than the current reference, the control circuit may limit the output current the first transistor provides to the output terminal to an amount corresponding to the current reference.

    Abstract: A system, e.g. an integrated circuit or part, may include a plurality of pads, e.g. digital I/O pads, each comprising a physical pad and associated pad circuit. In case of an ESD event affecting one or more of the digital I/O pads, PMOS devices configured in an output buffer section between an I/O pad supply rail and the physical output pad—within their respective pad circuits in the affected digital I/O pads—may all be turned on in response to the ESD event. This may allow the capacitance of each pad, in some cases approximately 3 pF capacitance per pad, to charge up, absorbing the energy of the ESD event and reducing the peak voltage the integrated circuit or part experiences as a result of the ESD event. The reduced peak voltage may be directly correlated with improved ESD performance of the product.

    Abstract: A system for automatically switching peripheral connectivity between two host devices based on respective connectivity of the hosts. The method may be used where peripherals are usually attached to one host and are automatically switched to a second host when the second host is attached to the system. A USB switching hub may be operable to automatically switch connectivity of the peripheral device(s) from the first host device to the second host device when the second host device is connected to the USB device. This automates the process for the end user when normally all peripherals are attached to one host, and some or all peripherals are shared with a second host when the second host is attached.

    Abstract: A temperature measurement device may be implemented by coupling a PN-junction, which may be comprised in a diode, to an analog-to-digital converter (ADC) that comprises an integrator. Different currents may be successively applied to the diode, resulting in different VBE values across the diode. The ΔVBE values thus obtained may be successively integrated. Appropriate values for the different currents may be determined based on a set of mathematical equations, each equation relating the VBE value to the temperature of the diode, the current applied to the diode and parasitic series resistance associated with the diode. When the current sources with the appropriate values are sequentially applied to the diode and the resulting diode voltage differences are integrated by the integrator comprised in the ADC, the error in the temperature measurement caused by series resistance is canceled in the ADC, and an accurate temperature reading of the diode is obtained from the output of the ADC.
