Abstract: A semiconductor package includes a flat metal leadframe including spaced apart portions, at least some of which constitute electrical connection leads. A filling material fills the spaces that separate the spaced apart portions of the leadframe to form a plate before fastening an integrated circuit chip to the front of the leadframe. Electrical connections are made between the chip and the electrical connection leads. The chip is then encapsulated on the front of the leadframe using a formed or attached encapsulant.

Abstract: Two processors are provided within a radio communication unit and linked together by a connection internal to the unit comprises. A process is effectuated for detecting transmission errors between the two processors. Codes transmitted between the processors are apportioned into frames which include indicators written by the processor sending the frames. On reception of the frames, the indicators are used by the receiving processor to validate the frames received. The codes transmitted may correspond to information contained in packets. The information of a packet that is intended to be transmitted via the internal connection may be placed in a single frame associated with the packet.
