Product Lifecycle & PCN

Lifecycle states (GA, NRND, EOL), change notifications, and our commitment to backward compatibility and seamless migrations.

1. Lifecycle states

GA (General Availability): actively sold and supported.
NRND (Not Recommended for New Designs): available for existing programs; not intended for new designs.
EOL (End of Life): sales end date and last‑time‑buy/last‑time‑ship timelines communicated; support transitions to sustaining.

2. Backward compatibility & migrations

We aim to maintain backward compatibility across releases and provide seamless migrations to updated chipsets/modules.
Where a change affects pinout, RF characteristics, or firmware, we provide migration notes and sample reference designs.
Drop‑in replacements: for most EOL modules, a mechanically and electrically compatible successor is offered whenever feasible.

3. Product Change Notice (PCN)

Issued for material changes (e.g., silicon revision, RF front‑end, BOM change, mechanical/thermal envelope).
Includes description, rationale, risk/impact, recommended actions, and effective dates.
Target notice windows depend on change type and supply constraints; we provide commercially reasonable advance notice.

4. Product Discontinuance Notice (PDN)

Communicates last‑time‑buy (LTB) and last‑time‑ship (LTS) dates, along with successor recommendations.
Includes migration guidance and any required certification updates for successor SKUs.
After LTS, we cease stocking inventory; RMA/service support follows warranty terms for shipped units (see Hardware Warranty & RMA).

5. Supply & allocation

During supply constraints, allocation policies may apply. We’ll coordinate with customers to prioritize critical programs and ensure continuity while successor products ramp.

6. Certifications & regulatory continuity

Where practical, successors retain regulatory equivalence to enable drop‑in replacement; otherwise, guidance is provided to update markings or documentation.
See RF Compliance & Certifications for regional status and labeling requirements.

7. Communication

PCN/PDN communications are delivered to customer contacts on file. To ensure you receive notices, keep your program contacts current or reach out via the Contact page.
