摘要： A microcontroller includes a memory, direct memory access (DMA) controllers and a microprocessor. The microprocessor maintains one or more memory protection (MP) configurations to control access to protected memory areas of the microcontroller. In response to a secure service call of an unsecure user-application, the microprocessor executes a state machine which disables interrupt requests, determining whether DMA controller configurations and MP configurations satisfy secure-service criteria. When the secure-service criteria are satisfied, at least one secure operation associated with the secure service call is performed, and memory areas accessed during the execution of the at least one secure operation are cleaned. The interrupt requests are re-enabled and a response to the secure service call is generated.

摘要： Embodiments of the present disclosure are directed to leadframe semiconductor packages having die pads with cooling fins. In at least one embodiment, the leadframe semiconductor package includes leads and a semiconductor die (or chip) coupled to a die pad with cooling fins. The cooling fins are defined by recesses formed in the die pad. The recesses extend into the die pad at a bottom surface of the semiconductor package, such that the bottom surfaces of the cooling fins of the die pad are flush or coplanar with a surface of the package body, such as an encapsulation material. Furthermore, bottom surfaces of the cooling fins of the die pad are flush or coplanar with exposed bottom surfaces of the leads.

摘要： A method for operating an electronic device includes while a display is in low power mode, detecting based on data collected by a time of flight (ToF) sensor, a movable object within a field of view of the electronic device; in response to the detecting initiating a period of detection having a plurality of frames, the period of detection being a time period over which a distance value indicative of a distance between the movable object and the display is detected; for each of the plurality of frames, changing the distance value to reflect whether the movable object is moving near or further from the electronic device; detecting that the distance value after the period of detection is less than a threshold distance value indicative of the movable object approaching the display; if the distance value is less than the threshold distance value, waking up the display.

摘要： A method and device for unlatching a door from a frame, using a keyless door latch system, is provided. In one embodiment, a secondary unlocking component receives a signal and derives power from the signal to provide a power source for the keyless door latch system. A microcontroller generates a control signal and an actuator, in response to receiving the control signal, actuates the secondary unlocking component, which allows an energy source, from an exterior of the door, to be transferred to the keyless door latch system for the unlatching of the door.

摘要： A microelectromechanical system (MEMS) gyroscope includes a driving mass and a driving circuit that operates to drive the driving mass in a mechanical oscillation at a resonant drive frequency. An oscillator generates a system clock that is independent of and asynchronous to the resonant drive frequency. A clock generator circuit outputs a first clock and a second clock that are derived from the system clock. The drive loop of the driving circuit including an analog-to-digital converter (ADC) circuit that is clocked by the first clock and a digital signal processing (DSP) circuit that is clocked by the second clock.

摘要： An interconnect structure for use in coupling transistors in an integrated circuit is disclosed, including various configurations in which ferroelectric capacitors exhibiting negative capacitance are coupled in series with dielectric capacitors. In one embodiment, the negative capacitor includes a dielectric/ferroelectric bi-layer. When a negative capacitor is electrically coupled in series with a conventional dielectric capacitor, the series combination behaves like a stable ferroelectric capacitor for which the overall capacitance can be measured experimentally, and tuned to a desired value. The composite capacitance of a dielectric capacitor and a ferroelectric capacitor having negative capacitance coupled in series is, in theory, infinite, and in practice, very large. A series combination of positive and negative capacitors within a microelectronic interconnect structure can be used to make high capacity DRAM memory cells.

摘要： A method to determine a relative delay between a current-overshoot signal and a write data signal for a hard disk drive preamplifier, the method including using a memory element to strobe a test current-overshoot signal with a test data signal; counting a number of strobed transitions of the test current-overshoot signal; adjusting the delay based on the number of strobed transitions; setting a phase difference between the current-overshoot signal and the write data signal according to the delay; and using the memory element to strobe the current-overshoot signal with the write data signal.
