Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Renesas Electronics today announced the expansion of its popular R-Car product family with the R-Car V4M series, a system-on-chip (SoC) for entry-level advanced driver assistance systems (ADAS). The new R-Car V4M series and the expanded R-Car V4H series offer powerful AI processing and fast CPU performance with a good balance of performance and power consumption. Their excellent TOPS/Watt performance and optimised power-saving features make them ideal for entry-level, cost-sensitive ADAS applications such as front-facing smart camera systems, surround view systems, automatic parking and driver monitoring systems.

The R-Car V4M and R-Car V4H families feature up to four Arm® Cortex®-A76 cores, delivering 32K to 81K DMIPS of application processing performance. and three Arm Cortex-R52 lock-step cores for up to 25K DMIPS of real-time operating performance. Thanks to a highly integrated design and advanced manufacturing process technology, these products deliver 9 to 34 TOPS of arithmetic power with extremely low power consumption and performance of 9 TOPS/watt. In a typical full-featured smart camera with an 8-megapixel sensor, the R-Car V4M consumes about 5 watts of power, which is 50 per cent lower compared to similar products on the market.

To date, Renesas has shipped more than 450 million automotive-grade R-Car products, including devices that meet the ASIL D quality rating, which is the highest level in the automotive safety integrity hierarchy and represents a minimisation of risk.

Key features of the R-Car V4M family and R-Car V4H family:

• Up to four Arm® Cortex®-A76 cores for application processing

• Up to three Arm Cortex-R52 lock-step cores; supports ASIL D real-time operation without an external MCU

• Dedicated deep learning and computer vision IP

• 3D graphics processing unit (GPU)

• Image Signal Processor (ISP) with parallel processing for machine vision and human vision

• Image renderer (IMR) for fisheye aberration correction or other mathematical operations

• Low power consumption

• Fast start-up of the camera display (less than 1 second)

• AUTOSAR software partition with expandable memory size

• Dedicated on-board interfaces: CAN, Ethernet AVB, TSN and FlexRay

• BOM optimised for NCAP, GSR2, L2+ with single chip SoC, no external MCU required

• Scalability within the R-Car product family

• Equipped with dedicated power management IC (PMIC) and power transistors
