Infineon now offers the industry’s most comprehensive portfolio for linking the real with the digital world – comprising an unparalleled range of hardware, software and security solutions for the connected age.
Strengthening the link between the real and the digital world
System design challenges solved on chip
Our Wi-Fi / Bluetooth Combo Chipsets and supporting software serve as application development platforms enabling multiple users to connect and seamlessly stream unique content to as many as 10 mobile devices simultaneously. The infotainment platforms include a Wi-Fi 6 (802.11ax) and Bluetooth combo solution that features Infineon‘s Real Simultaneous Dual Band (RSDB) architecture. RSDB enables two unique data streams to run at full throughput simultaneously by integrating two complete Wi-Fi subsystems into a single chip. Wi-Fi 6 enables gigabit-level throughput and improves reliability for content streaming to multiple devices at once. Two Wi-Fi 5 (802.11ac) and Bluetooth combo solutions empower car makers and automotive system suppliers with a scalable platform solution to address a wide range of vehicles with a uniform software architecture that minimizes development and system integration costs.
CYW89335 and CYW89359 Automotive Wi-Fi + Bluetooth Combos are pioneering Real Simultaneous Dual Band (RSDB) solutions providing simultaneous operation in both 2.4GHz and 5GHz bands as well as Multiple-Input Multiple-Output (MIMO) support.
RSDB solutions provide the necessary bandwidth and the software architecture required to support complex use-case scenarios for cars, enabling combinations of AP, Station, and P2P connections simultaneously. This allows automakers to support several simultaneous application scenarios: driver and passenger devices streaming high-bandwidth data and media content, mirroring phone/tablet displays (Apple CarPlay, Android Auto, and Mirrorlink), and external Wi-Fi hot-spot access for on-the-go connectivity without relying on cellular data service. All this while using Bluetooth hands-free calling with the integrated Bluetooth technology that provides coexistence support for shared Wi-Fi and Bluetooth operation in 2.4GHz band.
Automakers can leverage in-car Wi-Fi to deliver software upgrades and new features. Drivers can use a mobile device to check remotely on their car's location, gas levels and mileage. The same device can receive alerts about vehicle performance and diagnostics.
WiFi is the communication technology for Electric Vehicle (EV) charging infrastructure, both for optimizing energy transfer from the electric grid to cars and to facilitate convenient payment systems for car battery charging. WiFi-based Dedicated Short-Range Communication (DSRC) technology is also expected to play a key role in Vehicle-to-Everything (V2X) communications to improve safety and to create smart infrastructure for traffic management and eventually the enablement of the self-driving vehicle.
CYW89071 and CYW89072 are automotive qualified, WICED™ SMART ready, Bluetooth devices allow products to sip power at an incremental rate, enabling connectivity between the car and the latest mobile devices and wearable gadgets. Support for Bluetooth's Enhanced Data Rate (EDR) enables best-in-class wireless audio for hands-free calling and Advanced Audio Distribution Profile (A2DP) music streaming between a mobile device and the vehicle infotainment radio system.
The portfolio supports narrowband and newer wideband speech capabilities with a variety of SmartAudio™ algorithms, including packet loss concealment and bit error correction. Bluetooth's technology also enables drivers to use their smartphones to adjust the seat, temperature, and infotainment settings while providing vital data on automotive performance and diagnostics.
All automotive qualified, Bluetooth devices offer an industry-standard Host Controller Interface (HCI) and can be used with almost any Bluetooth stack, operating system and host processor.
