STMicroelectronics announced that the company’s Bluetooth chipset has been chosen by LensLogica for an innovative motorcycle helmet solution that allows hand-free wireless calls with any Bluetooth-enabled mobile phone and easy communication between two helmets that are within the Bluetooth transmission range of a few meters, enhancing safety and comfort.

The STLC2410 Bluetooth base-band chip allows telephone and intercommunication functions to be combined easily, so that a conversation between two helmets can be automatically interrupted to answer an incoming call and then resume at the end. In addition, the noise immunity of the radio chip allows LensLogica helmet solution to reject interfering radio signals and improve audio quality. ST’s chipset was the only one evaluated by LensLogica to meet their stringent noise- immunity requirements.

The helmet application has been designed by LensLogica with a dedicated user-friendly interface to offer comfortable access to intercom and GSM functions. In particular, attention has been paid during design to power consumption to achieve a full-day operating device and extremely low consumption of less than 5uA, in standby.
