Selection reference · illustrative scenario
Clock roles in the application
Cameras, locks, alarms and edge-recognition equipment require different acquisition, communication and event-time references. Select by device function.
Engineering selection review
Separate continuous operation from battery sleep, reviewing image/wireless inputs, RTC and temperature. Component parameters alone do not guarantee recognition performance or battery life.
Procurement and documentation
Include host, imaging or wireless chips and event-time and logging needs, plus the existing full code, sample and production quantities and delivery target. Discuss nominated international brands and domestic candidates separately, confirming parameters and documents by part.
Illustrative validation scenario
Test extended logging, reconnection, event wake and backup behavior, comparing samples on the same board.
Inquiry & validation checklist
- Host, imaging or wireless chips
- Event-time and logging needs
- Continuous/sleep states
- Temperature, enable and validation records
