Latest Bluetooth IC promotes adoption of low energy communications

Toshiba Electronics Europe (TEE) has launched a low power consumption Bluetooth IC that supports Bluetooth Low Energy (BLE) communications. The IC, the TC35667FTG, is to be targeted at various wearable and healthcare-orientated smart devices, sensors, as well as smartphone accessories, remote controllers and toys.

The number of Bluetooth Smart devices offering Bluetooth LE compatibility is growing rapidly in a wide variety of application areas. The new IC adopts an original low-power circuit design and integrates a highly efficient DC-DC converter, reducing peak current consumption to below 6mA and deep sleep current consumption to below 100nA.

The TC35667FTG also integrates an ARM processor, enabling download and execution of customer programs stored in EEPROM. It supports customiSation 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.

Housed in a 6mm x 6mm QFN40 package with 0.5mm pin pitch, the low power consumption IC will enable the adoption of Bluetooth LE communications in the small devices while also promoting long battery life. The IC supports server and client functions defined by GATT (Generic Attribute Profile).

Toshiba said that it planned to expand the device line-up to include support for automotive applications of Bluetooth Smart devices.
