Abstract: A method and apparatus for classifying a spatial environment as open or enclosed are provided. In the method and apparatus, one or more microphones detect ambient sound in a spatial environment and output an audio signal representative of the ambient sound. A processor determines a spatial environment impulse response (SEIR) for the audio signal and extracts one or more features of the SEIR. The processor classifies the spatial environment as open or enclosed based on the one or more features of the SEIR.

Abstract: A memory device includes first and second dummy word line portions. A dummy word line driver drives the first dummy word line portion. A voltage dropping circuit causes a voltage on the second dummy word line to be less than a voltage on the first dummy word line. At least one dummy memory cell is coupled to the second dummy word line portion, remains in standby until assertion of the second dummy word line, and performs a dummy cycle in response to assertion of the second dummy word line. A reset signal generation circuit generates a reset signal in response to completion of a dummy cycle by the at least one dummy memory cell. An internal clock signal is generated from an external clock signal and the reset signal and is used in performing a read and/or write cycle to a memory array.

Abstract: A leadframe including a metal oxide layer on at least a portion of the leadframe are disclosed. More specifically, leadframes with a metal layer and a metal oxide layer formed on one or more leads before a tin finish plating layer is formed are described. The layers of metal and metal oxide between the one or more leads and the tin finish plating layer reduce the formation of tin whiskers, thus reducing the likelihood of shorting and improving the overall reliability of the package structure and device produced.

Abstract: According to principles as discussed herein, an EEPROM cell is provided and then, after testing the code, using the exact same architecture, transistors, memory cells, and layout, the EEPROM cell is converted to a read-only memory (“ROM”) cell. This conversion is done on the very same integrated circuit die using the same layout, design, and timing with only a single change in an upper level mask in the memory array. In one embodiment, the mask change is the via mask connecting metal 1 to poly. This allows the flexibility to store the programming code as non-volatile memory code, and then after it has been tested, at time selected by the customer, some or all of that code from a code that can be written to a read-only code that is stored in a ROM cell that is composed the same transistors and having the same layout.

Abstract: A circuit includes an input terminal and a regulated supply line for supplying an electronic device with an electrostatic discharge protection and driver circuit for the electronic device. The supply line is coupled to the input terminal via the circuitry, so that current injected into the input terminal may produce a voltage increase on the regulated supply line. A comparator sensitive to the voltage at the input terminal and the voltage on the supply line is provided. A current sink coupled with the supply line and being activatable to sink current from the supply line is also provided. The comparator is configured for activating the current sink as a result of the voltage at the input terminal exceeding the voltage on the supply line of a certain intervention threshold.

Abstract: An electronic device includes a power management circuit generating output for a plurality of voltage monitors that each detect whether voltages received from a test apparatus are at least a different minimum threshold. The power management circuit also generates a test enable signal indicative of whether the test apparatus is supplying the minimum required voltages to the electronic device. A control circuit receives the output for the plurality of voltage monitors and the test enable signal and generates at least one control signal as a function of the output for the plurality of voltage monitors and the test enable signal. An output circuit receives the at least one control signal and generates an interface control signal that selectively enables or disables interface with analog intellectual property packages within the electronic device, in response to the at least one control signal.

Abstract: An RFID transponder includes a coding and modulation unit that generates a transmission signal by modulating an oscillator signal with an encoded bit signal. During a first and a second time segment, the encoded bit signal assumes a first and a second logic level, respectively. The transmission signal includes a first signal pulse having a first phase within the first time segment and a second signal pulse having a second phase that is shifted with respect to the first phase by a predefined phase difference within the second time segment. The transmission signal is paused for a pause period between the first and the second signal pulse. The pause period is shorter than a mean value of a period of the first time segment and a period of the second time segment.
