摘要： The present invention comprises a microcontroller unit including a processor for generating a power down signal. Control logic generates a hold signal responsive to the power down signal. A voltage regulator provides a regulated voltage responsive to an input voltage and powers down responsive to the power down signal. At least one digital device powered by the regulated voltage enters a powered down mode responsive to the voltage regulator entering the powered down state. The at least one digital device provides at least one digital output signal that is provided to an input/output cell. The input/output cell also is connected to receive a hold signal. The input/output cell maintains a last state of the digital output signal responsive to the hold signal when the at least one digital device enters the powered down state.

摘要： The method is described for selecting capacitors from a capacitor array for each bit of a SAR ADC. The process involves selecting a group of capacitors from the capacitor array and determining a weight of the selected group of capacitors. A determination is made if the weights of the selected group of capacitors are substantially equal to their desired values. If the weights are substantially equal to their desired values, the selected group of capacitors is associated with each bit of the SAR ADC. If the weights are not substantially equal to their desired values, a next group of capacitors from the capacitor array is selected for the bits. This process of selecting a group of capacitors and determining their weights is repeated until determined weight for a group of capacitors equals or is closest to the desired values.

摘要： A microcontroller unit includes a processor for generating a first control signal to start a comatose mode of operation for the microcontroller unit. Control logic responsive to the first control signal generates an enable signal at a first level and the control logic is further responsive to a second control signal for generating the enable signal at a second level. A voltage regulator generates regulated voltage from an input voltage. The voltage regulator shuts down to provide a zero volt regulated voltage responsive to the enable signal at the first level and powers up to provide a regulated voltage at an operating level responsive to the enable signal at the second level.

摘要： A method for coding a digital to analog converter of a successive approximation register analog to digital converter includes the steps of first switching capacitors associated with a bit from ground to a reference voltage. Next, a determination is made of whether a logical value of the bit is a first or a second value. If the logical value is the first value, capacitors associated with a next bit are switched from ground to a reference voltage. If the logical value is the second value, one half of the capacitors associated with the bit currently connected are switched from the reference voltage to ground.
