Mie Fujitsu and SST Announce Automotive Platform Development on 40 nm Technology

SuperFlash® Memory Technology to be Developed by First Pure-play Foundry in Japan

Yokohama, Japan and CHANDLER, Ariz., Aug. 09, 2017 – Mie Fujitsu Semiconductor Limited (MIFS), a Japanese pure-play foundry company, and Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, through its Silicon Storage Technology (SST) subsidiary, today announced their plans to develop an automotive platform on 40 nm technology using SuperFlash^® memory technology licensed by SST. MIFS will be the first pure-play foundry in Japan to offer the industry-standard SuperFlash technology platform. While the technology will be available for multiple applications, including Internet of Things (IoT) and high voltage, the focus will be on automotive AEC-Q100 (Grade 1) applications.

"We are thrilled to have the opportunity to partner with SST," said Masahiro Chijiiwa, executive vice president of Mie Fujitsu Semiconductor, "Customers currently have to go outside of Japan to manufacture their semiconductor devices. We have received a great demand for what we now have the ability to offer with this new partnership. The combination of our high-quality foundry services and SST's SuperFlash technology will yield an excellent offering to customers in several industries including automotive, IoT and high voltage."

"I am confident that the combination of SST and MIFS for a 40 nm embedded Flash platform will ultimately bring a great and needed product to the market," said Mark Reiten, vice president of SST. "This partnership presents a unique opportunity to combine SST's industry-standard SuperFlash technology with MIFS' years of automotive manufacturing experience."

SST's embedded SuperFlash memory solution offers low-power, high-reliability and high-density performance-driven IC designs. SuperFlash technology is based on a proprietary split-gate Flash memory cell with the following capabilities:

• Low-power program, erase and read operations
• High performance with fast read access
• Good scalability from 1 um technology node to 28 nm technology node
• High endurance cycling up to 500,000 cycles
• Excellent data retention of over 20 years
• Good performance at high temperature (Tj Max = 150 C) for automotive-grade applications
• Immunity to Stress-Induced Leakage Current (SILC)

The platform is expected to be available for client's test chips starting in calendar quarter one 2018. For more information, visit: http://www.fujitsu.com/jp/mifs/en/
