Socionext Introduces ISO26262 Certified
Smart Graphic Display Controllers
4th Generation Smart Graphic Display Controllers Enable Panoramic and Multi-displays
[Langen/Germany and Yokohama/Japan. July 15, 2022] --- Socionext, a global leader in the design and
development of innovative System-on-Chip products, has announced a new series of smart display controllers,
“SC1721/ SC1722/ SC1723 Series”, certified with ISO26262 for functional safety. Samples will be available at
the end of July 2022.
The automotive industry is currently undergoing major transformations that occur approximately once every
100 years. The E/E (Electrical/Electronic) architecture, which is the system structure of automobiles, is changing
from a distributed architecture to a domain/zone architecture. Automakers are adopting integrated cockpit
systems linking multiple displays, such as meters, In-Vehicle Infotainment (IVI), and head-up displays. Larger
display size and screen resolution are also driving the demand for improved image quality. Due to the changes,
complying with the ISO26262 functional safety standard is critical for new automotive ADAS and infotainment
systems development.
Socionext has been developing smart display controllers for automotive applications for many years. This fourth
generation is equipped with an APIX®3 SerDes-repeater function that allows daisy-chaining of multiple smart
display controllers, enabling up to four display connections in a chain. Compared to the previous generation,
this function greatly improves the wiring efficiency of the vehicle and facilitates the cooperation of multiple
displays. In addition, the company's proprietary SEERIS™ 2D graphics IP is integrated with cutting-edge
functions, such as LED control and pixel compensation by Local Dimming, and Warping-on-the-fly dynamic
interpolation of the Warp Map. Socionext improves vehicle safety by adding a mechanism to monitor external
LED driver error detection and internal algorithm, and supports functional safety (ASIL-B) by complying with
the ISO26262 development process.
These features enable new architectures, such as panoramic displays for dashboards, to meet a growing trend
of larger multi-display applications.
