Integrierte Schaltungspackung mit eingekapselter Batteriezelle

摘要

An integrated circuit package (10) encapsulates a volatile memory chip (12) and a backup battery (34) for preserving data in the event of loss of main power supply. The package includes a lead frame (20) assembly encapsulated within a body (32) of non-conductive material, with the memory chip being mounted onto a base plate (22) on one side of the lead frame. The battery is supported in offset relation by axial power leads on the opposite side of the lead frame. The integrated circuit chip, the battery, the lead frame assembly and the gold interconnect wires (36) are completely encapsulated within the molded package body.
