21ic STMicroelectronics (ST) has released the Cannes Wi-Fi (STiH390) SoC, targeting the HD HEVC Wi-Fi® IP client and interactive set-top box market.

When watching a favorite TV show connected to a wireless network via a mobile phone, tablet, and set-top box, users expect a perfect visual experience at home. However, limited network coverage is depressing, which also inhibits the potential of Wi-Fi bearer services, causing MSOs (Multi-Service Operators) to find alternative solutions that are cost-effective, flexible, and easy to install. The program to provide users with the perfect multi-room multimedia service.

In order to meet the demand for high-quality, high-definition video for family economy, STMicroelectronics and Quantenna have developed the Cannes Wi-Fi (STiH390) system chip. The chipset integrates Quantenna's market-proven Wi-Fi 802.11 IP with ST's latest HD HEVC system chip to dramatically reduce cost without sacrificing performance.

Philippe Notton, vice president of the STMicroelectronics business unit and general manager of the Consumer Electronics Division, said: "We are very much looking forward to this groundbreaking solution to become a reference solution for the Wi-Fi HD network video market, to promote the industry's large-scale deployment performance and affordable Wi-Fi IP client products, through the Cannes Wi-Fi system chip, we optimized the cost and development speed of the chipset-integrated Quantenna Wi-Fi 802.11 IP, and in new and existing video-distribution It verifies the functionality of the new product, and the test results prove that its performance is very good, giving full play to the technical advantages of the latest Wi-Fi 802.11 ac."

Lionel Bonnot, senior vice president of marketing and business development at Quantenna, said: "We are very pleased to see STMicroelectronics take the lead in introducing a set-top box system chip that integrates 4x4 11ac Wi-Fi, the first STMicroelectronics integrated Quantenna digital baseband IP product. The next-generation integration that meets customer requirements, the baseband processor supports 4x4 802.11ac/11n wave2, providing state-of-the-art Wi-Fi performance and robustness to meet the family's internal video transmission reliability requirements."

The Cannes Wi-Fi chipset is compatible with the STMicroelectronics Cannes family of system chips, allowing OEMs to leverage the vast development ecosystem and easily design innovative client set-top boxes with multiple middleware products.

The main features of the STiH390 include:

· ARM® multi-core CPU with 6K DMIPS performance;

· Wi-Fi 802.11.ac 4x4;

· Support high dynamic range kernel decoding and display functions to achieve excellent visual effects on a new generation of TV sets;

· MaliTM 400 GPU supports smooth 3D user interface and games;

· Faroudja® post-processing video transcoding engine, the image quality is excellent in multi-screen applications;

· Extensive interoperability testing with all major encoder vendors to verify the superior performance of HEVC 10-bit;

· Rich and future-oriented interfaces, including USB3 and HDMI; advanced secure video content protection based on DRM;

· 28nm FD-SOI silicon technology, integrated with energy-efficient RF modules and analog functions, excellent energy efficiency, and support for a very compact fanless design;

STMicroelectronics has now begun offering Cannes Wi-Fi/STiH390 samples to major customers.
