STMicroelectronics has announced its 55nm embedded Flash (eFlash) process technology, which will be implemented in its next-generation automotive microcontroller (MCU) chips. ST is extending its production of eFlash technology to this advanced process node at its 300mm manufacturing facility at Crolles, France.
The 55nm eFlash technology builds upon ST’s 20-year expertise in embedded Flash and is also the continuation of the company’s successful 90nm eFlash automotive microcontroller family. Automotive market demands are driving the technology beyond the performance currently delivered by 90nm-based chips. Next-generation automotive systems will increasingly require MCUs with more computational performance, better power efficiency and greater memory content to meet market requirements in automotive applications, such as functional safety, tougher emission standards or ADAS (Advanced Driver-Assistance Systems) solutions. The new technology will enable ST to provide substantial performance improvement and greater value to its customers and will be the basis for ST’s future Automotive 32-bit Power Architecture-based MCU roadmap.
ST’s eFlash technology has been developed, and also will be manufactured, at the company’s Crolles facility, which is automotive certified and is considered the world’s leading manufacturing site for 55nm eFlash. Same-site development and manufacturing means ST can deliver high process stability and exceptionally high levels of quality, in addition to long-term availability. At Crolles, ST is in production with 55nm technology for automotive products and has already produced several fully working embedded Flash technology test vehicles implementing key automotive system IP.
ST’s first MCUs to implement the 55nm eFlash technology are expected to target automotive applications, including engine management and transmission, car body controllers and safety/ADAS. First 55nm embedded-Flash product is expected to be available for customer sampling in mid-2011, and automotive qualification in 2013.
