Infineon Technologies AG and TSMC announced the companies are preparing to introduce TSMC’s Resistive RAM (RRAM) Non-Volatile Memory (NVM) technology into Infineon’s next generation AURIX™ microcontrollers (MCU).
Embedded Flash microcontrollers have been the main building blocks of automotive electronic control units (ECU) since the introduction of the first engine management systems. They are essential components for clean, safe, and smart cars, used in propulsion systems, vehicle dynamics control, driver assistance, and body applications. They enable major innovations in the automotive space with regards to electrification, E/E architectures and automated driving. Currently, the majority of MCU families in the market are based on embedded Flash memory technology. RRAM is a next step in embedded memories that allows to further scale to 28 nm and beyond.
The Infineon AURIX TC4x microcontroller products combine performance extension with latest trends in virtualization, security, and networking features to enable the next generation of software-defined vehicles and E/E architectures. TSMC and Infineon successfully created the basis for introduction of RRAM in the automotive domain. This will put AURIX microcontrollers on a broader technology and supply basis. RRAM offers high disturb immunity and allows bit-wise write without the need of erase. Endurance and data retention performance has comparable performance with Flash technology.
“TSMC and Infineon have a long track record of successful collaboration, including the first AURIX generation with TC2x products. We have also partnered on RRAM NVM technology for almost a decade in a range of different applications,” said Dr. Kevin Zhang, Senior Vice President of Business Development at TSMC. “Moving the TC4x to RRAM will open opportunities in terms of shrinking MCUs into smaller nodes, and we are excited to be working with a leader like Infineon.”
“AURIX TC3x is well established as a first-choice automotive microcontroller in many applications domains. AURIX TC4x based on TSMC’s RRAM technology further expands this success with increased ASIL-D performance, artificial intelligence capabilities and the latest networking interfaces including 10Base T1S Ethernet and CAN-XL,” said Thomas Boehm, Senior Vice President and General Manager of Automotive Microcontrollers. “RRAM technology creates a significant potential for performance expansion, power consumption reduction, and cost improvement.”
Infineon is already shipping samples of its AURIX TC4x family to lead customers that are based on TSMC’s 28 nm eFlash technology. The first samples based on 28 nm RRAM technology will be available to customers by end of 2023.
