Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain integrated circuits by type and function, help identify and use chips from datasheets, describe manufacturing and supply chain at a general level, and support learning and repair.

A set of electronic circuits fabricated on a single piece of semiconductor material, usually silicon, containing transistors, resistors and interconnections, from simple logic and analogue chips such as shift registers and radio receivers to microprocessors, memory and systems on a chip; integrated circuits are the foundation of modern electronics.

What it is for: Electronics, computing and communications.

It can be identify a chip from its markings; read datasheets and pinouts; explain IC types and manufacturing; support design, repair and sourcing.
