#EFM32howto 3. Reducing external components for portable health devices


“Minimizing energy consumption is critical to the success of mobile healthcare devices because it frees users from the worry of frequent battery changes or re-charging. We expect products based on the EFM32 and Continua-Certified protocol stack to be amongst the most energy-efficient available.”

–  Mike Mazzola, CEO of LNI  – 

With rapid development and commercialization of portable medical technology and smart consumer electronics, consumers can easily check their health status on their medical or fitness devices. Although today’s health electronics succeeded to have high portability, the battery life and user-friendliness remains challenging for advanced latest models. The EFM32 Giant Gecko’s large Flash memory size of 1024KB and versatile low power energy modes are ideal for all health devices, with advanced functionality or remote operation. Giant Gecko MCUs enables larger data capacity and longest battery life expectations. Ultimately, the user avoids inconvenience of transferring data and re-charging batteries on a frequent basis.

In addition to the large Flash memory and low power consumption, the EFM32 Giant Gecko microcontroller features a variety of optional peripherals making portable health devices more user-friendly. The USB interface handles up to 14 endpoints and supports for USB host, device and bootloader, and the LCD/TFT controller makes it possible to have advanced animations without CPU intervention. Additional SPI functionality enables rapid transfer of data between devices, making it possible to realize cloud host systems and the “health everywhere” idea. By having all the essential features and peripherals in one microcontroller, the Giant Gecko meets the high performance and efficient connectivity requirements for energy sensitive mobile health applications.
