Abstract: PROBLEM TO BE SOLVED: To improve functionality of devices in a package by combining a first device with a second device, the second device having at least one feedthrough connector for coupling the first device to one of a plurality of pins via the second device. SOLUTION: A plurality of different devices 12 can be mounted on one lead frame 14 die paddle 16 construction without requiring an excessive bond wire length and bond angle i.e., without extending a bond wire on a second device 12B, while maintaining pin compatibility by an IC package 10. The IC package 10 enables this by providing a first device 12A coupled to one of a plurality of pins 20 via the second device 12B by a feedthrough connector 28 located on the second device 12B.

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.

Abstract: Operationsverstärker mit totem-pole-verbundenen Ausgangstransistoren, der Eingänge aufweist, die zur wählbaren Kopplung von Signalen und Spannungspegeln an diese mit Multiplexern gekoppelten sind. Die Nieder- und Hochleistungstransistoren können zusätzlich zur normalen Kopplung von Signalen mit diesen hart ein- oder ausgeschaltet werden. Der Betrieb der Ausgangstransistoren kann dynamisch geändert werden, um nur positiv verlaufende Signale weiterzuleiten, negativ verlaufende Signale weiterzuleiten, in einem hochohmigen Tristate-Zustand versetzt zu werden, fest mit einer Versorgungsspannung verbunden und/oder fest mit einer gemeinsamen Versorgungsleitungsrückführung verbunden zu werden. Ein kernunabhängiges Peripheriegerät (CIP) kann ebenfalls mit dem Operationsverstärker gekoppelt sein, um die Multiplexereingänge dynamisch in Echtzeit zu ändern, ebenso wie externe Steuersignale an eine Steuerschaltung, die mit den Multiplexern gekoppelt ist.

Abstract: Current sources are selectively coupled to a current controlled frequency determining circuit of an oscillator. A buffer amplifier has an input coupled to the current controlled frequency determining circuit of the oscillator and the buffer amplifier output is selectively coupled to the current sources not coupled to the frequency determining circuit of the oscillator. The buffer amplifier output maintains substantially the voltage of the current controlled frequency determining circuit on each of the current sources not coupled to the frequency determining circuit so that when any current source is coupled thereto, there is substantially no voltage difference therebetween. This substantially prevents generation of undesirable frequency spikes during coupling of the current sources to the frequency determining circuit of the oscillator.
