Renesas, TSMC Team Up to Develop 28-nm MCUs

5 Sep

Renesas and TSMC recently announced they are working together to develop 28nm MCUs. Renesas and TSMC are teaming up to manufacture automotive MCUs for applications such as autonomous vehicle sensor control, coordinated control among electronic control units (ECUs), fuel-efficient engine control for green vehicles, and motor inverter control for electric vehicles.

According to Renesas and TSMC, next-generation MCUs are important for future autonomous vehicles as they enable high-precision use of 3D radar to monitor the environment surrounding the vehicle, integration of data from multiple sensors, as well as real-time judgment processing for autonomous operation.

“By leveraging TSMC’s 28nm high-performance, energy-efficient technology, we believe we can showcase how best we optimize one of our advanced technologies to meet the demands and innovation for the next generation of automotive devices,” said BJ Woo, TSMC’s vice president of business development, in a statement.

At the same time, MCUs with improved computing performance and greater function integration are needed given increasingly stringent emissions requirements and the growing cruising range in electric vehicles (EVs) and plug-in hybrid vehicles Additionally, there is a need large-capacity flash memory to allow more fine-grained support for the environmental regulations and standards of various countries as well as to enable over-the-air (OTA) wireless updating of control programs.

With the 28nm eFlash process technology developed through their cooperation Renesas and TSMC say they will be able to meet the demand of next-generation automotive computing. The two companies say they will be able to deliver up to four times the program memory capacity and greater than four-fold performance improvement compared to current 40nm technology. The new MCUs will also boast multiple CPU cores, more advanced security, and support for multiple interface standards.

“The auto industry is currently undergoing a major transformation, with next-generation green vehicles and autonomous-driving vehicles on the horizon,” said Ryuji Omura, an executive vice president at Renesas. “Innovative semiconductor technology is essential to accelerate the development of next-generation automobiles.”
