Real-time clock (RTC) modules are increasingly being designed with ultra-low power modes to extend battery life. But that’s not the only trend happening in this space as miniaturization and high integration are also driving demand due to their benefits in space constrained applications.
These RTC modules are being used in a range of devices like:
- IoT
- Wearables
- Healthcare devices
- Smartwatches
- Hearing aids
Integration of electronic components like the addition of temperature sensors or event detection continues its move into RTC modules. This allows the modules to be used across these smart applications and potentially into more use cases in the future where power savings and high levels of integration are desired.
Additionally, with IoT networks and AI-power devices on the rise for real-time decision-making and automation, RTC modules are becoming popular as well.
