Dialog Semiconductor has announced that Samsung has implemented Dialog’s wireless microcontroller unit (MCU) in its latest Galaxy Fit. The Galaxy Fit is a slim and fashionable fitness tracker that enables users to reach their fitness goals with its intuitive tracking features. It tracks a wide range of activities and offers enhanced sleep analysis and stress management technology for users to monitor their wellbeing throughout the day.

Samsung designed the Galaxy Fit band to be easy for users to interact with while on the go, which meant it needed to sync with smartphones to allow users to receive alerts and messages.

Additionally, because the device is easy to style and comfortable to wear all week long, it also required a solution that would support seamless smartphone connectivity while conserving energy to extend battery life. Samsung found its solution with the DA14697, a wireless microcontroller unit within Dialog’s DA1469x SmartBond line that is suitable for wearable devices.

“Samsung’s elegantly designed Galaxy Fit epitomises the features consumers are looking for in next generation fitness trackers,” said Sean McGrath, Senior Vice President and General Manager of Dialog Semiconductor’s Connectivity and Audio Business Group.

“Our collaboration with Samsung not only builds on Dialog’s leadership position in wearable technology, but it serves as a strong example of connected living enabled by low power Bluetooth connectivity with best-in-class power consumption features.”

The DA1469x family, the latest addition to Dialog’s SmartBond line, is the most advanced, feature-rich range of MCUs for wireless connectivity. It offers developers greater processing power, resources, range and battery life for a wide variety of connected consumer applications, including high end fitness trackers and other wearable devices.

The family is also the first set of Bluetooth wireless microcontroller SoC’s in production with a dedicated application processor based on the ARM Cortex-M33 processor. To conserve power, the devices are equipped with a Sensor Node Controller (SNC) that runs autonomously and wakes the application processor only when needed, and a Power Management Unit (PMU) activates the different processing cores as required.
