Infineon, TSMC to introduce RRAM for automotive
Infineon Technologies is preparing to launch TSMC’s Resistive RAM (RRAM) Non-Volatile Memory (NVM) technology in its next generation of automotive microcontrollers.
RRAM is an emerging embedded flash technology for microcontrollers that scales to 28nm process technologies and beyond with the reliability needed for automotive designs. The technology is more immune to interference and allows bit-wise write without the need of erase, while having the endurance and data retention performance comparable to current flash memory technology.
Part of the chip shortage for automotive over the last two years has been the lack of capacity at older process nodes with the older embedded flash technology.
The next generation Aurix TC4x microcontroller, to be launched next year, is intended to support new virtualization, security, and networking features for software-defined vehicles. The development of the RRAM memory process with TSMC will allow broader availability of Aurix microcontrollers.
“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 new 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,” said Thomas Boehm, Senior Vice President and General Manager of Automotive Microcontrollers. “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.
“RRAM technology creates a significant potential for performance expansion, power consumption reduction, and cost improvement,” he added.
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.
