Toshiba Corporation today announced the launch of “TC35667FTG”, a low power Bluetooth IC that supports Bluetooth® Low Energy (LE)[1] communications. Sample shipments start today.


Recently, the number of Bluetooth® Smart[2] devices offering Bluetooth® LE compatibility is growing. 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. It promotes long life for small coin cell batteries and will facilitate adoption of Bluetooth® LE communications for small devices, such as wearable healthcare devices, sensors and toys.

The IC also integrates an ARM® processor, enabling download and execution of customer programs stored in EEPROM. It supports customization of applications, eliminating need for any external microcontroller.

Toshiba will expand the device line-up to include in automotive applications, supporting a wide range of Bluetooth® Smart devices.
