Infineon Technologies : and TSMC announce RRAM technology for the AURIX™ TC4x product family for the automotive industry

Munich, Germany – November 25, 2022 – Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) and TSMC today announced that the companies have announced the launch of TSMC’s Resistive RAM (RRAM) Non-Volatile Memory (NVM) technology Prepare in Infineon’s next-generation AURIX™ microcontroller (MCU).

Embedded Flash microcontrollers have been the main building blocks of automotive electronic control units (ECUs) since the first engine management systems were introduced. They are essential components for clean, safe and intelligent cars, used in powertrain systems, vehicle dynamics control, driver assistance and body applications. They enable significant innovations in the automotive sector in terms of electrification, new E/E architectures and automated driving. Currently, most MCU families on the market are based on embedded flash memory technology. RRAM is a next step in embedded memory, enabling further scaling to 28nm and beyond.

Infineon’s AURIX TC4x microcontroller products combine performance enhancement with the latest trends in virtualization, security and networking to enable the next generation of software-defined vehicles and new E/E architectures. TSMC and Infineon have successfully created the basis for the introduction of RRAM in the automotive sector. This puts AURIX microcontrollers on a broader technology and range basis. RRAM offers high noise immunity and allows bit-wise writing without the need for erasing. Endurance and data retention performance are comparable to flash technology.

“TSMC and Infineon have a long track record of working together, including the first AURIX generation with TC2x products. We have also collaborated on RRAM NVM technology for almost a decade in a number of different applications,” said Dr. Kevin Zhang, Senior Vice President of Business Development at TSMC. “Moving the TC4x to RRAM will open up new possibilities in terms of scaling MCUs to smaller nodes, and we’re excited to partner with a leader like Infineon.”

“The AURIX TC3x is established as the automotive microcontroller of choice in many application areas. Based on TSMC’s RRAM technology, the AURIX TC4x further builds on this success with increased ASIL-D performance, artificial intelligence capabilities and the latest network interfaces including 10Base T1S Ethernet and CAN-XL,” said Thomas Boehm, Senior Vice President and General Manager of Automotive Microcontrollers “RRAM technology creates significant potential for increasing performance, reducing power consumption and lowering costs.”

Availability

Infineon is already shipping samples of its AURIX TC4x family based on TSMC’s 28nm eFlash technology to leading customers. The first samples based on 28 nm RRAM technology will be available to customers by the end of 2023. For more information, see infineon.com/aurixTC4x
