ST MCU at the core of Pebble smart watch
STMicroelectronics has revealed that its STM32 MCU is the brain controlling the Pebble smart watch for iPhone and Android. In addition to providing the 32bit performance and processing capacity required for advanced signal processing, the device claims to offer real-time responsiveness, exceptional power efficiency, and highly integrated peripherals and memory required for the most demanding embedded applications, indicated the company.
The Pebble smart watch seamlessly connects to iPhone and Android smartphones using Bluetooth to alert users with a silent vibration to incoming calls, emails and text messages. The embedded STM32 F2 MCU affords Pebble users a balance of functionality, battery life and customisability, complete with beautiful downloadable watch faces and Internet-connected apps.
When dealing with wearable technology, the packaging size is also extremely important. At just 4 x 4mm, the STM32 F205 chip uses a minimal amount of space.
In addition to the STM32, Pebble also uses ST's LIS3DH MEMS digital-output motion sensor. The LIS3DH senses acceleration along all three axes and contributes to the watch's usefulness via ultra low-power operational modes that allow advanced power saving and smart embedded functions.
The watch is available to order at http://getpebble.com. At this time, the following smartphones are compatible with Pebble: iPhone 3GS, 4, 4S, 5 or any iPod Touch with iOS 5 or iOS 6 and Android devices running OS 2.3 and up.
