IC package having direct attach backup battery

An integrated circuit device package assembly comprising:

• a first insulating body having a support surface;
• a plurality of conductive leads carried on said support surface with one of said leads providing a positive power lead having a terminal contact lead portion projecting from said first insulating body and another of said leads providing a negative power lead having a terminal contact lead portion projecting from said first insulating body;
• a second insulting body on said first insulating body with a portion of said leads sealed therebetween, said second insulating body having a cavity for receiving an electronic circuit device, and having a socket for receiving a user loadable backup battery;
• an electronic circuit device in said cavity and having a plurality of input/output nodes electrically connected to said conductive leads;
• and
• the positive and negative power terminal contact lead portions being exposed within said socket for respectively directly engaging positive and negative terminals of a backup battery when the backup battery is loaded into said socket;
• whereby when a backup battery is loaded into said socket, said backup battery can supply backup electrical power to said electronic circuit device.

In an integral electronic circuit package of the type including a circuit device having multiple input/output nodes encapsulated within a body of nonconductive material, a plurality of connector pins mounted on said body of nonconductive material and projecting externally thereof, and a plurality of conductive finger leads encapsulated within said body of nonconductive material electrically connecting said input/output nodes to said connector pins, the improvement comprising:

• said body of nonconductive material having a cavity defining a socket for receiving positive and negative terminals of a backup battery;
• one of said conductive finger leads providing a first power lead having a terminal contact portion projecting into said socket, the projecting terminal contact portion of the first power lead being disposed for direct electrical contacting engagement with the positive terminal of the backup battery when the backup batter is loaded into said socket;
• and,
• another of said conductive finger leads providing a second power lead having a terminal contact portion projecting into said socket, the projecting terminal contact portion of the second power lead being disposed for direct electrical contacting engagement with the negative terminal of the backup battery when the backup battery is loaded into said socket;
• whereby when the backup battery is loaded into said socket, said backup battery can supply backup electrical power to said circuit device.
