LVDS LCD video processor for automotive displays

Renesas Electronics Corporation has recently unveiled the RAA278830 Video Diagnostics Bridge IC, a cutting-edge dual Low-Voltage Differential Signaling (LVDS) LCD video processor. This innovative IC is designed to cater to the needs of ISO 26262-compliant ASIL B automotive display systems, including heads-up displays (HUD), digital instrument clusters, camera monitor systems (CMS), and electronic mirrors.

With the increasing reliance on display systems in automotive safety applications, the demand for clear and reliable images has never been more crucial. The RAA278830 is equipped with Functional Safety features that actively prevent image corruption by monitoring signal integrity and video content. Its internal diagnostics and measurement engines can detect various issues such as frozen video, incorrect colors, and broken or corrupt images, ensuring optimal driver safety.

Featuring dual open-LDI input/output and an ISO 26262 Functional Safety ASIL B rating, the LCD video processor incorporates CRCs, parity, BIST, and redundancy safety mechanisms throughout the data path. Additionally, its video diagnostic capabilities encompass monitoring of video timing, signal integrity, and content, while Spread Spectrum technology minimizes EMI and an image enhancement engine enhances image quality.

Moreover, the RAA278830 boasts a range of advanced features, including SPI-Flash-based OSD, embedded font-based OSD, SPI boot capability, AEC-Q100 Grade 2 qualification, and support for multi-bank for fail-safe OTA updates. These features make it a versatile and reliable solution for various automotive display applications.

Jason Kim, Vice President and General Manager of the Configurable Mixed-Signal Division at Renesas, expressed, “Our automotive customers have consistently requested functional safety features in our video processing technology. The RAA278830 fulfills these demands by providing a comprehensive set of features to create secure, easy-to-implement, and cost-effective LCD displays for passenger vehicles of all kinds.”

The RAA278830 LCD video processor is packaged in a compact 72-lead, 10- x10-mm SCQFN package and is accompanied by the RTK278830 evaluation board, offering a complete solution for automotive display system development.
