Semidrive X9H - Intelligent Cockpit Platform Reference Design

In addition to several R5 cores, the X9H adopts a 6-core A55, with a CPU computing power up to 36kDMIPS, and a GPU computing power up to 140GFLOPS. MPS and Semidrive developed a X9H reference board to realize a smart cockpit solution with up to four screens. The reference board’s input end is directly powered by a 12V battery. Since the SoC power supply rail is typically below 1V, a two-level power supply scheme is recommended to improve the system’s conversion efficiency and support battery voltage fluctuations during crank and load dump conditions.
