Bluetooth 5 IC for automotive applications

By eeNews Europe

The TC35681IFTG will be fully AEC-Q100 qualified by spring 2019 and is based on an Arm Cortex-M0 CPU. The mixed-signal device has both RF and baseband parts to provide a complete solution in a single QFN40 ‘wettable flank’ package measuring 6.0mm x 6.0mm. The wettable flank package makes automatic visual inspection easier and to ensures the soldering quality required to withstand vibration.

Besides normal Bluetooth functions, such as Host Control Interface (HCI) profile and GATT profile, new functions as found in Bluetooth core specification 5.0 are provided – including 2Mbps data rates, long range and advertising extension functions, all of which are stored in the internal mask ROM. In addition, the TC35681IFTG integrates a high gain power amplifier and realises +8dBm for long distance communication.

The device features a wide operating temperature range of -40°C to +125°C and has high RF transmission power and excellent RF reception sensitivity (the link budget is 113dB @125kbps in long range operation).
