    摘要: A system includes a voltage pump to generate a first pump voltage from an analog voltage signal. The system further includes switching pad to receive an analog signal from an external source and route the analog signal to analog processing circuitry over one or more analog signal busses based on the first pump voltage and the analog voltage signal.

    摘要: In one embodiment, an integrated circuit device includes a power on reset (POR) circuit and a stochastic reset circuit configured to control enabling and disabling of the POR circuit. The stochastic reset circuit may have a value from among many possible values. The POR circuit may be enabled during a power up sequence of the device when the value of the stochastic reset during the power up is not a value designated to allow disabling of the POR circuit. The stochastic reset circuit may be configured such that the probability of the POR circuit being disabled during the power up is extremely low. After the power up sequence, the stochastic reset circuit may be controlled to allow disabling of the POR circuit to conserve power.

    摘要: In one example, a chip includes integrated components configured to operate in the digital domain and the analog domain. An I/O pad located on the chip is configured to provide an external device access to the integrated components. A multifunction I/O interface cell between the I/O pad and the integrated components is configured to selectively connect different combinations of the components to the same I/O pad at different times. The multifunction I/O interface cell may include a first switching device connected to ground, a second switching device connected to a reference voltage, an analog input/output buffer, and a digital input/output buffer.
