1. Purpose of the gate
Last-time buy gives customers a final date to order before the part is withdrawn, with a migration path.
Customers' final demand can be hard to estimate, especially for long-lived infrastructure and industrial products. The plan reaches every customer with active designs, adds an agreed buffer, and checks that wafers or die bank, substrates, filters and test capacity can cover it.
Radio products add a further question: which of the customers' own approvals rely on this module, and what a successor would mean for them. A successor with different approvals may force customers to recertify their products, so the plan states this early and offers support where the company can give it.
The gate also agrees what happens to stock, die bank and test hardware after the final builds, and how long the company will answer quality and certification questions about shipped parts. These commitments are written into the notice where customers need them.
Partial withdrawals follow the same gate. A band, a package option, an assembly site or a firmware branch can be withdrawn while the product continues, and customers using that part of the product need the same notice, migration advice and final order date. The certification file is updated to show which configurations remain on the market, and the notice is coordinated with any regulatory filings needed to keep the remaining approvals valid. The review ends by confirming the dates in the notice, the people who will answer customer questions, and how late requests will be handled.
The gate sits at the start of the stage End of Life and belongs to the product track. In one line: Customers receive a final date to place orders before the part is withdrawn, with a migration path.
