Cypress Semiconductor Corp. announced production availability of a combo solution that delivers robust 2×2 MIMO 802.11ac Wi-Fi and Bluetooth connectivity to vehicles, enabling multiple users to connect and stream unique content to their devices simultaneously. The new Cypress CYW89359 combo solution is the industry’s first to implement Real Simultaneous Dual Band (RSDB) technology, which enables two unique data streams to run at full throughput simultaneously, by integrating two complete Wi-Fi subsystems into a single chip. The solution’s advanced 2.4-GHz Wi-Fi and Bluetooth coexistence engine delivers optimal performance for 2.4- and 5-GHz 802.11ac Wi-Fi and dual-mode Bluetooth/Bluetooth Low Energy (BLE) simultaneously.
The RSDB architecture of the CYW89359 combo solution allows applications such as Apple® CarPlay and a Wi-Fi Hotspot to operate concurrently without the performance degradation caused by real-time switching between radio frequency (RF) bands, which is required by today’s devices. The CYW89359 is fully automotive qualified with AECQ-100 grade-3 validation and is being designed in by numerous top-tier car OEMs and automotive suppliers as a full in-vehicle connectivity solution, supporting infotainment and telematics applications such as smartphone screen-mirroring, content streaming and Bluetooth voice connectivity in car kits.
