Tiny RTC Features Empower Designers to Develop Close-packed Wearable Devices

The tiny real-time clock feature is one of the important drivers for the real-time clock IC market. Compact RTC components are enabling designers of space-constrained systems to deliver extended battery life to devices. This trend is very prominent for medical monitors and portable terminals. Companies in the real-time clock IC market are increasing production capabilities in compact RTC components that eliminate the need for central microcontrollers for timekeeping.

Microcontrollers waste battery life, especially when small batteries power the system. Hence, companies in the real-time clock IC landscape are increasing production expertise in industry-standard power-management circuitry to provide timekeeping with extended battery life. Also, ultra-small wafer-size components significantly reduce the overall design size of wearable systems. Companies in the real-time clock IC market are competing to develop compact external circuitry by incorporating features such as integrated load caps, power management, and trickle chargers.

Innovations in Design for IoT and Wearable Devices Aid Power Conservation

Real-time clock IC components have revolutionized the Internet of Things (IoT) and wearables sector. For the development of ultra-low power devices, manufacturers in the real-time clock IC market are increasing research efforts to thoroughly understand the dynamics of size and connectivity requirements in devices. Manufacturers in the RTC IC space should strengthen their technology supply chain by steering innovation in new semiconductor designs, passive components, software, and the cloud.

The low-duty activity cycle of most IoT and wearable designs has extended battery life, even while executing tasks. However, power conservation still poses a challenge in IoT and wearable devices. Since human intervention is not guaranteed, there is a growing need for ‘self-awareness’ in these devices for efficient power conservation. Hence, manufacturers in the real-time clock IC market should innovate new designs for devices that can starve continuously active circuits of power to meet battery life requirements.
