A 16bit low-power microcontroller that integrates a liquid crystal display (LCD) driver optimized for smart watches and other wearable devices. Equipped with a real-time clock function and power supply circuit for driving larger HD 2048-dot LCDs. Sensor processing capability supports multiple sensors to achieve advanced operation utilizing sensor data, such as pedometer with navigation function, as well as display sophisticated graphs and icons in activity meters and other wearable devices when used in combination with an LCD and multiple sensors. A clock function provides greater design flexibility to fit various needs (i.e. health monitoring and management), while maintaining normal watch operation.
