ST wins application in Pebble Smart Watch

September 19, 2013 // By Graham Prophet
STMicroelectronics' STM32 microcontroller is the processor controlling the Pebble Smartwatch for iPhone and Android.

The Pebble Smartwatch connects to iPhone and Android smartphones using Bluetooth to alert users with a silent vibration to incoming calls, emails and text messages. The real-time performance and power efficiency of the embedded STM32 F2 MCU gives Pebble users a balance of functionality and battery life as well as full customisability - complete with downloadable watch faces and useful Internet-connected apps.

When dealing with wearable technology, the packaging size is also extremely important. At just 4mm x 4mm, the STM32 F205 chip uses a minimal amount of space while delivering performance and battery life.

In addition to the STM32 microcontroller, 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.
