摘要： Apparatus for providing multiple of discrete voltage levels to drive a liquid crystal display (LCD) from an LCD module on board a microcontroller chip includes a charge pump with a switched-capacitor that develops the discrete voltages as multiples of the value of a base voltage that remains substantially without change irrespective of change in the supply voltage. A switched-capacitor charging circuit selectively charges a capacitor to produce successive additive charges individually retrievable from the capacitor. An LCD drive selectively transmits the discrete voltage levels to activate the LCD according to status of an external system under the control of the microcontroller. Voltage losses that may occur during the switched-capacitor charging are compensated to maintain the levels of the discrete voltages free of decay. Compensation is achieved by overcharging the capacitor by an amount substantially equivalent to the amount of voltage loss on the capacitor, using active feedback obtained from monitoring the charge on the capacitor.

摘要： A microcontroller for use in battery charging and monitoring applications is disclosed. The microcontroller includes a microprocessor and various front-end analog circuitry including a slope A/D converter and a multiplexer for allowing a plurality of analog input signals to be converted to corresponding digital counts indicative of signal level. The microcontroller further includes an on-chip temperature sensor, used in conjunction with the A/D converter, to monitor the temperature of the microcontroller. The temperature sensor generates and uses a differential voltage that is obtained across the base-emitter functions of two compatible bipolar transistors having dissimilar emitter areas. This differential voltage is proportional to temperature and may be sampled by the A/D converter to obtain a digital count indicative of the temperature of the microcontroller.

摘要： An oscillator with temperature compensation produces a stable clock frequency over wide variations of ambient temperature, and it includes an oscillation generator, two independent current generators, a transition detector and a clock inhibitor. The outputs of the two programmable, independent current generators are combined to provide a capacitor charging current that is independent of temperature. The oscillator is capable of three modes of operation: fast mode, slow/low power mode and sleep mode, which are controlled by the transition detector in response to external control signals. When the transition detector transitions from one mode to another, it controls the clock inhibitor to block a clock output of the oscillator generator for a predetermined number of clock cycles to allow the clock output to stabilize. The oscillator is implemented on a single, monolithic integrated circuit.

摘要： A remote keyless entry (RKE) transponder has a programmable selective wake-up filter for determining whether the RKE transponder should wake-up to process a received signal. The wake-up filter correlates the timing of an input signal's carrier amplitude on and off time periods to a predefined programmable time period profile for a desired signal which has a certain carrier on time (time period on) and a certain carrier off time (time period off) arranged into a coded “header.” When a received signal matches the predefined time period profile, then the RKE transponder will wake-up to process the incoming signal data. The predefined time period profile may be programmable and may be stored in a header configuration register. Each RKE transponder has unique predefined time period on and time period off profiles.

摘要： A fast start-up circuit for use in integrated circuits where there are internal nodes of reference circuits that need to be charged to a predetermined voltage level at a quicker rate than that delivered by the typical ramping up of supply power. The circuit a current driven approach, which is unique from the voltage driven approaches found in the prior art. The circuit is comprised of a high gain reference circuit and a current generator. The reference circuit is comprised of a bias generator and a high gain amplifier. The invention is characterized by a current generator which is capable of rapidly injecting relatively high levels of current into the reference circuit or sinking relatively high levels of current from the reference circuit or both. The invention is further characterized by a current driven feedback loop which deactivates the current generator once start-up is achieved and the high gain reference circuit approaches the quiescent point.

摘要： Apparatus for digitally trimming the output frequency of a real-time clock is disclosed. The output frequency of a divider chain is adjusted by the contents of a trim constant register. The amount of correction and direction (slow or fast) to be effected is determined by the trim constant register. During "slow" real-time clock operation, the divider chain "shortens" the next second produced by the real-time clock. During "fast" real-time clock operation, the production of the next second is blocked and then a portion of the "blocked" signal is "added back" to effectively "lengthen" the next second produced by the real-time clock.

摘要： An operational amplifier is trimmed electrically using non-volatile fuses. The non-volatile fuses may be programmed electrically without destroying any passivation layers or other devices on the electronic component. In the case of an integrated circuit analog component, the trimming may be performed either at the wafer level or at the packaging level. The trimming may be performed specifically to adjust the quiescent current or offset voltage of the operational amplifier.
