Intersil Announces Automotive Industry’s First Full HD LCD Video Processor

By Neha Rastogi July 11, 2017

Intersil, a subsidiary of Renesas Electronics Corporation, has announced the TW8844 LCD video processor that interfaces with the latest generation of automotive SoCs. It’s highly integrated first high-definition 1080p LCD processor with analog video decoder along with 2 scalers and MIPI-CSI2 SoC interface. 
 
It offers the reliability needed by automakers to ensure that the rearview camera systems comply with the U.S. Federal Motor Vehicle Safety Standard (FMVSS-111) for preventing injury or death caused by backover accidents. The sensor also allows migration from analog to digital camera systems and supports a variety of video interfaces and LCD panel resolutions up to full HD 1920 x 1080. 
 
As far as the applications are concerned, the LCD processor is ideal for center stack/head units, full display rearview mirrors, instrument cluster displays, and dual-headrest rear-seat entertainment systems. The TW8844 model with MIPI-CSI2 and TW8845 model fitted with BT.656 output display live video with graphics overlay in less than 0.5 seconds after vehicle ignition.

Moving on to the features, the processor offers a robust rear camera architecture to overcome the fast boot reliability issues inherent with today’s more complex center-stack systems. Presently, the head units are prone to the operating system (OS) software freezes and hang-ups that prevent the rear camera from displaying live video. 
 
The TW884X eliminated this issue by monitoring the SoC and camera output to determine if they are in a frozen or corrupted state. Is any glitch is detected, it bypasses the SoC and instantly displays the rearview camera video. 

Key Features and Specs

• Support several video inputs from analog or digital HD cameras
 
• Provide system flexibility to drive most LCD panels
 
• Two input measurement engines with frozen/abnormal image detection diagnostics to monitor input from the SoC and camera
 
• EEPROM fast boot allows register programming without need for external microcontroller
 
• Two separate H/V scalers for outputting up to 1080p (1920 x 1080) resolution, allow processing of two different sources simultaneously while outputting different data to the SoC and display, or they can simultaneously drive two different displays with different content
 
• Automatic Contrast Adjustment (ACA), white balance and gamma correction optimizes video quality
 
• Smooth input switching allows switching between various input sources without screen flicker
 
• AEC-Q100 Grade-2 qualified for operation from -40°C to +105°C

Availability & Pricing

The TW8844 video processor with MIPI-CSI2 output is available now in a 14mm x 20mm, 156-lead LQFP package, and is priced at $10.00 USD in 1k quantities. The TW8845 video processor with BT.656 output is available now in a 14mm x 20mm, 156-lead LQFP package, and is priced at $9.50 USD in 1k quantities.
