Which entity manufactures
which chip family.

Two practical notes for buyers.

First, the difference between Yes and Yes·QC is operational, not commercial. Both ship at production volumes. The QC variant indicates that the manufacturing run is overseen by Cardzgroup\'s own QC team at a partner facility — usually because the regional sister entity is closer to the customer than corporate but still wants corporate-managed quality assurance.

Second, the Spec rating is not a refusal — it means we will absolutely make the product, but it is not on a standing production schedule. Lead times are longer and minimum order quantities are higher. If a chip family shows Spec everywhere except corporate, it usually means corporate is the right place to place the order.
