Bluetooth® wireless technology ICs

Bluetooth® classic/low energy dual and Bluetooth® low energy(LE) are widely used by audio, mobile, wearable and healthcare devices. In the coming years, Bluetooth  classic/low energy dual and Bluetooth® low energy devices will become increasingly pervasive. For over ten years, Toshiba has been serving as a Bluetooth Special Interest Group (SIG) (Note 1) Promoter contributing to the wider uptake of Bluetooth solutions. Toshiba is a leading source of Bluetooth connectivity ICs and original Bluetooth protocols and profiles.
