My own mobile phone core chip realizes 28nm process full line upgrade

The Tianjin Science and Technology Support Program major project "based on 28nm multi-core smart phone core chip" has been accepted and certified by the expert group, and has achieved international advanced level, marking China's independent research and development of mobile phone core chips, from the mainstream technology in the 40nm market to the international advanced The 28nm process has taken an important step in the whole line upgrade, which is of great significance to lead the development of China's mobile intelligent terminal technology and industry. Spreadtrum Communications (Tianjin) Co., Ltd., the leading company of the city's small giants, undertook the launch of the 28-nm high-integration quad-core smartphone platform, SC883XG, yesterday. Spreadtrum uses the internationally advanced 28nm semiconductor process to develop and design mobile phone core chips, which will help mobile phone manufacturers develop high-end mobile phones with cost-effective solutions, and promote the rapid improvement of the IC design industry in this city. It is reported that Spreadtrum SC883XG has begun to provide samples, and is expected to put into mass production in the second half of this year.

The "28nm-based multi-core smartphone core chip" project is a major scientific and technological project implemented under the joint support of the municipal science committee, Binhai New Area, and the airport economic zone. As one of the leading core chip suppliers for 2G, 3G and 4G wireless communication terminals in China, Spreadtrum Communications (Tianjin) Co., Ltd. introduced a highly integrated TD-SCDMA/GSM/GPRS/EDGE multimode with advanced 28nm technology. The quad-core smartphone platform - SC883XG, adopts the most advanced 28nm processing technology of mobile communication. The core adopts ARMCortex-A7 quad-core architecture, the main frequency can reach 1.4GHz, and supports Android4.4 intelligent operating system. Compared with the previous generation 40nm process, the area of ​​the functional die is reduced by about 40%, which reduces the cost, greatly increases the number of chips that can be produced on a single wafer, reduces the dynamic power consumption by about 40%, and improves the overall performance by more than 20%. Spreadtrum SC883XG platform has significant advantages in power control, thermal management and chip size due to the most advanced process technology available at the commercial level.

Spreadtrum Communications is one of the largest integrated circuit design companies in China, the world's third largest mobile phone baseband chip supplier, and its products have been widely used in Samsung, HTC, ZTE, Huawei, Lenovo, Xiaomi and other major domestic and foreign mobile phone manufacturers, GSM market possession The rate is over 24%; the TD market share is over 60%. In 2010, Spreadtrum Communications Co., Ltd. established a wholly-owned subsidiary, Spreadtrum Communications (Tianjin) Co., Ltd. in Binhai New Area, and built Tianjin Company into the Group's North Headquarters Base.
