IC supports BLE communications in wearable devices
A low power consumption Bluetooth IC, which supports BLE communications, has been launched by Toshiba Electronics Europe. The TC35667FTG has been designed for use in wearable and healthcare-orientated smart devices, sensors, as well as smartphone accessories, remote controllers and toys.
The IC adopts an original low-power circuit design and integrates a highly efficient DC-DC converter. This reduces peak current consumption to below 6mA and deep sleep current consumption to below 100nA. An ARM processor is also integrated, enabling download and execution of customer programs stored in EEPROM. It supports customization of applications, eliminating the need for any external microcontroller. The receiver has a sensitivity of -91dBm and transmitter output power can be varied from 0dBm to -20dBm in 4dB steps.
The device is housed in a 6 x 6mm QFN40 package with 0.5mm pin pitch and supports server and client functions defined by GATT. The low power consumption IC will enable the adoption of Bluetooth LE communications in small devices while also promoting long battery life.
There are plans by the company to expand the device line-up to include support for automotive applications of Bluetooth Smart devices.
