It has been announced by Cypress Semiconductor that Pioneer Corporation has integrated Cypress WiFi and Bluetooth Combo solution into its flagship in-dash navigation AV receiver. The solution enables passengers to use their smartphone apps on the receiver screen via Apple CarPlay or Android Auto, which allows smartphone voice recognition to search for information or respond to text messages.

The Cypress WiFi and Bluetooth combo solution uses Real Simultaneous Dual Band (RSDB) technology so that Apple CarPlay and Android Auto can operate concurrently without degradation caused by switching back and forth between bands.

Takashi Miyake, General Manager of Consumer Car Electronics Business Planning Division at Pioneer, stated: “People want to be able to access their favourite smartphone apps and features everywhere they go, and our new flagship in-dash navigation AV receiver brings that user experience to their cars via Apple CarPlay and Android Auto. Robust wireless connectivity is a critical part of that experience, and Cypress’ wireless combo solution with its unique RSDB technology offers the dedicated bandwidth required to deliver the performance customers expect.”

Sudhir Gopalswamy, executive vice president of the Microcontrollers and Connectivity Division at Cypress, added: “Switching between bands for smartphone mirroring just doesn’t deliver the user experience people want, but our wireless solution with dual-WiFi subsystems delivers double the bandwidth to bring an optimal mirroring experience to Pioneer. This solution is helping Cypress to capture the growing chip content in cars, and we’re seeing demand for similar forward-looking infotainment features for the connected living room.”

The Pioneer AVH-W8400NEX receiver uses Cypress’ CYW89359 combo solution, which includes an advanced coexistence engine that enables optimal performance for dual-band 2.4 and 5GHz 802.11ac WiFi and dual-mode Bluetooth/Bluetooth Low Energy (BLE) simultaneously for superior multimedia experiences. The CYW89359’s RSDB architecture enables two unique data streams to run at full throughput simultaneously by integrating two complete WiFi subsystems into a single chip.

The CYW89359 is fully automotive qualified with AECQ-100 grade three 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.
