Chip identification pads for identification of integrated circuits in an assembly

摘要

Chip identification pads for identification of integrated circuits in an assembly. In one example embodiment, an integrated circuit (IC) assembly includes a controller, a plurality of ICs, a shared communication bus connecting the controller to the plurality of ICs and configured to enable communication between the controller and each of the plurality of ICs, and a set of one or more chip identification pads formed on each IC. Each set of chip identification pads has an electrical connection pattern. The electrical connection pattern of each set is distinct from the electrical connection pattern on every other set. Each distinct electrical connection pattern represents a unique identifier of the corresponding IC thereby enabling the controller to distinguish between the ICs.

1. A printed circuit board assembly (PCBA) comprising:
a controller; a plurality of integrated circuits (ICs); a shared communication bus connecting the controller to the plurality of ICs and configured to enable communication between the controller and each of the plurality of ICs; a set of one or more chip identification pads formed on each IC, each set of chip identification pads having an electrical connection pattern that is independent of the controller, the electrical connection pattern of each set being distinct from the electrical connection pattern on every other set, each distinct electrical connection pattern representing a unique identifier of the corresponding IC thereby enabling the ICs to self-identify to the controller and enabling the controller to distinguish between the ICs.
