The system is sufficiently flexible that it can be used for the full spectrum of automotive camera applications including advanced driver assistance systems (ADAS), surround and rear viewing systems, in-cabin cameras (for gesture recognition, driver eye monitoring, or light level inspection purposes), and autonomous driving.
MARS aims to enable shorter design cycles, reduced engineering costs, and to assist automotive design teams in the implementation of imaging systems by providing them with a mix-and-match solution. Through it, various items of hardware can be combined in a robust and highly adaptable system with a compact form-factor. Due to the many different boards available, engineers have access to ON Semiconductor’s portfolio of image sensors and co-processors, plus various automotive communications protocols from a group of third party supply partners. This provides scope in terms of finding the combination that best fits specific system requirements. The platform can accommodate multiple combinations due to consistent signal/power definitions for the interconnects utilised by these respective boards.
Creating custom boards (each capable of accommodating a different sensor option), testing out high-speed interface standards, or writing code for drivers, is no longer necessary. MARS is supported by a complete ecosystem, encompassing software development tools, schematics, Gerbers, bill-of-materials (BOM) and more. A comprehensive user guide is also included within the accompanying documentation.
The support of commonly used communication standards (such as GMSL, FPD-Link, LVDS, MIPI, Ethernet) enables direct interfacing with existing vehicle ECUs. ON Semiconductor is working with an ecosystem of partners spanning lens developers, third party ISP vendors, communications IC vendors, software developers and SoC vendors. MARS modules are already pre-qualified with a range of these third party products and the company will expand these offerings going forward.
MARS development boards are available now. The MARS product recommendation tool provides a step by step process to select the correct board(s) for a design. There is an Introduction to MARS webcast, and a blog, “Optimizing the Automotive Camera Development Phase Using a Modular Design Approach”. Board pricing, ON adds, enables fully configured cameras at $1,000.00 or less.
