Making outline
- Package one mixed-signal capacitance-controller die with wire-bond interconnect and physical firmware/test/loading interfaces
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Identified requirement; no researched making route or qualified output yet.
- Current memory-first method needs source and compatibility review.
