Cypress advances premium automotive infotainment user experience with Wi-Fi 6 connectivity solution
10 January 2019
Cypress Semiconductor has expanded its wireless connectivity portfolio for automotive infotainment with a trio of new products.
The Wi-Fi and Bluetooth combo chipsets and supporting software serve as application development platforms that enable multiple users to connect and stream content to as many as 10 mobile devices simultaneously. The new infotainment platforms include a Wi-Fi 6 (802.11ax) and Bluetooth combo solution that features Cypress’ Real Simultaneous Dual Band (RSDB) architecture.
RSDB has become the de facto standard for premium connected infotainment experiences, says Cypress, enabling 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.
Cypress also added two Wi-Fi 5 (802.11ac) and Bluetooth combo solutions to its portfolio, providing car makers and automotive system suppliers with a scalable platform solution to address a range of vehicles with a uniform software architecture designed to minimise development and system integration costs.
Premium infotainment systems require high-throughput, multi-role, concurrent operation to implement wireless mirroring for applications such as Apple CarPlay, Android Auto and Mirrorlink. Cypress’ Wi-Fi and Bluetooth combo solutions meet these needs and also offer simultaneous Wi-Fi Hotspot and content access, and multi-band/multi-radio coexistence for video and Bluetooth audio.
The Cypress CYW89650 2×2 plus 2×2 Wi-Fi 6 and Bluetooth 5.0 combo solution delivers more than 1Gbps throughput, and the RSDB architecture enables concurrent operation for these use cases in high-performance infotainment systems without audio or video degradation. The new CYW89459 2×2 Wi-Fi 5 and Bluetooth 5.0 combo with RSDB builds on Cypress’ existing automotive Wi-Fi 5 solutions, enabling more connected devices to the head unit and including emerging features such as WPA3 security, Wi-Fi Location and Wi-Fi Aware.
Cypress’ automotive wireless solutions are fully automotive qualified with AEC-Q100 grade-3 validation. According to Cypress its existing solutions have been designed in by numerous top-tier car OEMs and automotive suppliers and are in production vehicles today supporting infotainment and telematics applications such as smartphone screen-mirroring, content streaming and Bluetooth voice connectivity in car kits.
Cypress’ automotive portfolio includes Traveo and PSoC microcontrollers, CapSense capacitive-sensing solutions, TrueTouch touchscreen solutions, Wi-Fi, Bluetooth and USB connectivity solutions, power-management ICs (PMICs), and NOR flash, F-RAM and SRAM memories.
