Toshiba Electronics Europe has launched a Bluetooth Low Energy Communication IC which adopts Bluetooth Core Version 4.1 and is suited for use with Scatternet devices. The TC35667WBG-006 is suitable for Bluetooth Smart products, such as wearable sport and lifestyle technology, remote controls, smartphone accessories and devices for the IoT.

The Scatternet standard defines two functions in the Bluetooth Core specification, for version 4.0 and higher. Adopted devices have to support either multiple or simultaneous connections with Master and Slave devices or multiple connections between two or more Master devices at the same time. Toshiba’s new IC supports both functions with Bluetooth Low Energy, making it easy to create a network with very small devices.

The TC35667WBG-006 is configured with ROM software for Scatternet and multipoint connections and combines the functionality and compact size needed to equip a Bluetooth low energy communication network in low-profile applications, such as contactless cards, tags and tickets.

Compatible from voltages of 1.8 to 3.6V, the TC35667WBG-006 operates with current consumptions down to 5.9mA and has a deep sleep mode that reduces current consumption to just 0.5μA. On-board functionality includes DC/DC converter, low drop-out regulator, a general-purpose ADC and PWM function. User program function and a wake-up signal for a host device are also available.

In order to meet the demand for ever thinner Bluetooth devices, the TC35667WBG-006 is housed in a very thin, chip-scale package with dimensions of just 2.88x3.04x0.3mm high. Toshiba also supplies the IC in a QFN package.
