Why this exists

Every electronics company is quietly bleeding money to the same four problems.

Not solved by another distributor portal, another spreadsheet, another portal login — solved by everyone reading one current, canonical record.

The problem
The EOL notice arrives after the last-time-buy has passed
PCNs go to an inbox nobody reads. By the time the shortage surfaces, the redesign is forced.
How Semi360 solves it
Every PCN tracked, years-to-EOL forecast per part. You're told the day status moves — drop-in alternates attached.
A forced respin runs $50K–250K in NRE and requalification. A planned last-time-buy is a purchase order.
Comp360 · Xref360 — lifecycle alerts never metered
Core360 · the Semi360 data layer

The data is the product. Core360 is the engine that reads it.

42.6M sources — datasheets, PCNs, errata, compliance docs — normalized into one record per part, every field traceable to its source. Core360 is the engine that reads it; every product is a different view of the same record.

Core360 · reading the record live
Why is MAX3232CSE not recommended for new designs?
A product change notice moved it to Not Recommended for New Designs; last-time-buy has already passed. MAX3232ECSE and SP3232EEN are the two drop-in routes we can evidence.
