    Abstract: An Integrated Circuit (IC) (10) package is disclosed comprising an IC chip (11) with a microcontroller (12) therein having an n-bit data bus, and up to n pins (34-38) electrically coupled to the microcontroller (12). The IC package also includes a control register coupled to the microcontroller for receiving enable and disable signals from the microcontroller. One or more of the pins have one or more functional blocks associated thereto. Each functional block defines a specified function for its corresponding pin. Thus, each pin having a plurality of corresponding functional blocks has a number of potential functions equal to the number of corresponding functional blocks. The specific function for a given pin is selected by the enable signal from the control register which selects the appropriate functional block upon appropriate command from the microcontroller. By using pins with multiple functions, the instant invention permits an n-bit architecture microcontroller to use less than or up to n pins.

    IPC: H03K7/06

    Abstract: A microcontroller having digital to frequency converter and pulse frequency modulator capabilities. The digital to frequency converter (DFC) generates a 50 percent duty cycle square wave signal that may be varied in frequency, wherein the 50 percent duty cycle square wave signal is directly proportional and linear with a count value put into an increment register. The pulse to frequency modulator (PFM) generates pulses having pulse widths of the input clock for each rollover of a counter. The frequency of these pulses is directly proportional and linear with the count value put into the increment register.

    Abstract: The present invention relates to a microcontroller that may be configured to operate without the accompaniment of any external components. The microcontroller can function in a proper manner from the application of only power and signal lines with no external components required. The microcontroller has integrated internal reset and oscillator circuitry into the microcontroller. The microcontroller has also integrated simple external components such as current limiting resistors and pull up and pull down resistor into the microcontroller in order to avoid application specific external components.
