Power And Operating Modes
- Active current: Not characterized in seed; extract active current from datasheet tables.
- Sleep / standby current: Not characterized in seed; extract sleep/standby current from datasheet tables.
- Supply rails: Not characterized in seed; capture allowed supply rail range from datasheet.
- Notes: Seed values are search hints only. Verify power modes, rail limits, startup requirements, and reference design passives from the datasheet.
Procurement Classification
- JLC class: Extended Part
- JLC note / assembly basis: EasyEDA/JLC verified common drivers, isolation, and actuation seed
- Assembly status: jlc_extended
- Price-break table: Not captured in seed. Store only timestamped price-break snapshots when intentionally refreshed.
- Live stock: intentionally not stored as durable selection data; refresh externally before ordering.

Selection Notes
- Good for: reuse when package, electrical ratings, footprint, and assembly class match the project constraints
- Avoid when: Not captured yet.
- Known layout constraints: Verify package land pattern, decoupling requirements, thermal pad, RF keepouts, crystal routing, and boot straps from the datasheet.
- Equivalent search hints: match category
