Freescale and Tongji University launch a window lift system reference design

On August 30, Freescale Semiconductor and Tongji University jointly launched a reference design for automotive window lift systems. The reference design is based on the S12 MagniV S12VR64 mixed-signal microcontroller, enabling an easy-to-use, powerful anti-clamp vehicle window lift control system that helps automotive OEMs reduce development time and accelerate time-to-market.

The single-chip S12VR64 is based on Freescale's innovative LL18UHV technology, which enables extended analog integration on the MCU, allowing developers to directly connect high-voltage signals and power to the MCU in their automotive designs, saving board space and improving System quality, reduced complexity, and cost savings. Using the S12VR64 MCU in a new automotive window lift reference design helps reduce system BOM, board size, and system performance.

In the past automotive electronics designs often required multiple devices, including some that were fabricated using a high-voltage process, used to connect batteries and power brakes, and used a low-voltage digital logic process. This poses a challenge to the ultimate application of space constraints.

Sun Zechang, deputy dean of the School of Automotive Engineering at Tongji University, said: “The S12 MagniV mixed-signal MCU optimizes the integration of high-precision analog components with a reliable S12 16-bit MCU. We chose the S12VR64 for anti-clamp window design that can truly meet cost savings. Demand, reduced board size, and reduced time-to-market time. In these respects, the S12VR64 goes far beyond traditional multi-component solutions."

Tongji University’s academic achievements in the field of automotive technology enjoy a good reputation both at home and abroad. Tongji Automotive College is located in Shanghai Automobile City and has close cooperation with OEMs and auto parts manufacturers. The Tongji University and Freescale Automotive Electronics Laboratory was established in 2003. The lab focuses on battery management, powertrain, chassis and safety, R&D of body and in-vehicle infotainment systems, and hybrid electric vehicle/electric vehicle technology development. . The cooperation between the two parties has achieved a number of remarkable results. For example, fuel cell vehicles based on the Freescale Qorivva MPC55xx MCU have been used in the 2008 Beijing Olympic Games and the 2010 Shanghai World Expo.

Raymond Cornyn, product controller director of Freescale Automotive Microcontrollers, said, “The launch of reference window design for electric window lifter based on Freescale's S12VR64 MCU is our leading position in the field of automotive semiconductors and mature process technology to continuously create optimal solutions. An important step in the program is Tongji University is one of the top universities in the automotive electronics field in China, and we will continue to cooperate in the continuous launch of solutions that meet the needs of the automotive market."

The S12 MagniV mixed-signal MCU family uses a full-featured S12 16-bit MCU for a wide range of applications, software compatibility with other S12 devices, and tool reusability. When developers apply this reference design, they can build on previous work.
