Infineon AIROC CYW43455 WiFi and Bluetooth combo chip now in TomTom satellite navigation devices

Infineon Technology leverages TomTom satellite navigation devices with its AIROC CYW43455 Wi-Fi and Bluetooth combo chip.

According to Infineon, the AIROC wireless solution combines WiFi 5 and Bluetooth 5.0 on a single chip and adds fast wireless connectivity that is critical to the navigation device. Infineon’s AIROC family includes a range of wireless solution that delivers high performing connectivity.

The TomTom Go Discover downloads map updates three times faster than other navigation devices, powered by the integrated 5Ghz WiFi frequency band. Furthermore, with the integrated Bluetooth interface, the TomTom Go Discover can also be connected to the smartphone, making both real-time traffic information and TomTom’s premium live services available at all times, which include up-to-date information on fuel prices, parking availability, and the localization of charging points for electric vehicles.


The AIROC wireless connectivity portfolio offers 1×1 WiFi 5, Bluetooth, and operates in the 2.4GHz and 5GHz frequency spectrum. The WiFi 5 mode supports 20MHz, 40MHz and 80MHz channels for data rates up to 433.3Mbps, and all rates specified in 802.11/a/b/g/n are also supported. This triples the throughput and transmission speed over WLAN and significantly improves scalability, according to Infineon.

The high-data transmission speed proves beneficial when streaming media such as HD videos, transferring and storing files, as well as for extending the range of WiFi networks. Furthermore, the WiFi 5 specification helps extend the battery life. Once the WiFi interface has exchanged data at a high rate with its access point, the radio is immediately deactivated and goes back to sleep mode, reducing overall power consumption.
