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： 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： A digital power supply controller is disclosed for controlling the operation of a switched power supply. The controller is contained within an integrated circuit package enclosing an integrated circuit chip. A plurality of inputs are provided on the package for interfacing with the switched power supply for receiving sensed inputs therefrom. A plurality of outputs provide switch control signals for turning on and off switches in the switched power supply. An integrated digital controller on the chip receives the inputs and generates the outputs, and includes an integrated instruction based processing engine for providing a portion of the digital control of the digital controller. A memory associated with the processing engine stores instructions for the processing engine.
