摘要： An apparatus for providing power control to a real-time clock oscillator is disclosed. The apparatus includes a clock oscillator, a set of current limiting resistors and a set of latches. The current limiting resistors are coupled between a power supply and the clock oscillator. Coupled to the clock oscillator and the current limiting resistors, the latches control the current limiting resistors to limit the amount of current flowing from the power supply to the clock oscillator such that the power consumption by the clock oscillator is minimized.

摘要： A microcontroller with a mixed analog/digital architecture including multiple digital programmable blocks and multiple analog programmable blocks in a communication array having a programmable interconnect structure. The single chip design is implemented by integration of programmable digital and analog circuit blocks that are able to communicate with each other. Robust analog and digital blocks that are flash memory programmable can be utilized to realize complex design applications that otherwise would require multiple chips and/or separate applications. The programmable chip architecture includes a novel array having programmable digital blocks that can communicate with programmable analog blocks using a programmable interconnect structure. The programmable analog array contains a complement of Continuous Time (CT) blocks and a complement of Switched Capacitor (SC) blocks that can communicate together. The analog blocks consist of multi-function circuits programmable for one or more different analog functions, and fixed function circuits programmable for a fixed function with variable parameters. The digital blocks include standard multi-function circuits and enhanced circuits having functions not included in the standard digital circuits. The programmable array is programmed by flash memory and programming allows dynamic reconfiguration. That is, “on-the-fly” reconfiguration of the programmable blocks is allowed. The programmable analog array with both Continuous Time analog blocks and Switched Capacitor analog blocks are offered on a single chip along with programmable digital blocks. The programmable interconnect structure provides for communication of input/output data between all analog and digital blocks.

摘要： There is provided an oscillator circuit capable of obtaining stable frequency by avoiding output having unstable frequency that is likely to occur to an operation/stop-control-feasible type oscillator circuit when oscillation begins. In such an oscillator circuit, an oscillation permitting signal (EN) sets an oscillator section in oscillation-operable state, whereby a controller section starts operation. The controller section that has stared its operation change an oscillation-frequency control signal (VR) into a signal value corresponding to predetermined oscillation frequency so as to set oscillation frequency at an oscillator section. Further on, the oscillator section outputs an oscillation signal in response to a detection signal (MON) that is outputted after a detector section compares a signal inputted therein with a predetermined signal value and detects that the inputted signal reaches a predetermined signal value. Thereby, transient state of an oscillation-frequency control signal (VR) can be detected. That is, there can be avoided an output of an unstable oscillation signal due to a transient oscillation-frequency control signal (VR).

摘要： A method and a system for supplying power to a microcontroller with a single cell battery. A power supply pump circuit may be incorporated with the microcontroller having dynamic interaction. The microcontroller sends its power requirements to the power supply pump circuit and in response, the power supply pump circuit controls the operating voltage with optimal efficiency. The dynamic update of power supply pump circuit results in an efficient use of the power supply pump circuit and thus results in a reduction of the number of dry cell batteries to only a single cell. Incorporation of the microcontroller and power supply pump circuit onto a single chip reduces the pin number requirements as well as the space required on the printed circuit board.
