UNISOC (Chinese: 紫光展锐; pinyin: Zǐguāng zhǎn ruì), formerly Spreadtrum Communications, Inc. (Chinese: 展讯通信有限公司; pinyin: Zhǎnxùn Tōngxìn Yǒuxiàn Gōngsī), is a Chinese fabless semiconductor company headquartered in Shanghai which produces chipsets for mobile phones. UNISOC develops its business in two major fields - consumer electronics and industrial electronics. Consumer electronics includes smartphones, feature phones, smart audio systems, smart wearables and other related devices. Industrial electronics cover fields such as LAN IoT, WAN IoT and smart displays.
From 2021, it has been the fourth largest mobile processor manufacturer in the world, after MediaTek, Qualcomm and Apple, with 9% of global market share.
Background
In 2021, Tsinghua Unigroup, UNISOC's former parent company, was on the verge of bankruptcy. After a year-long restructuring, a private equity consortium headed by Chinese government-backed Wise Road Capital took over in 2022 and now controls the company. In addition to Wise Road, the company’s shareholders include the China Integrated Circuit Industry Investment Fund, a Chinese government-backed investment fund for chips, which has a 13% stake in the company.
Research and development
UNISOC products support a broad range of wireless communications standards, including GSM, GPRS, EDGE, TD-SCDMA, W-CDMA, HSPA+ and TD-LTE. UNISOC has a global R & D layout, with more than 5,000 employees worldwide, 90% of whom are R&D personnel.
The company originally produced chips for GSM handsets, but most of its resources in the late 2000s were then focused on the Chinese TD-SCDMA 3G standard. In addition to GSM and combined GSM/TD-SCDMA baseband chipsets, they also supplied chips for two Chinese mobile TV standards: TD-MBMS and CMMB. UNISOC (then known as Spreadtrum)'s customers accounted for 50% of TD-SCDMA handset sales in China Mobile's round of TD-SCDMA trials in 2008.
UNISOC, then still known as Spreadtrum, was formerly a public company listed on NASDAQ, but agreed to an acquisition by Tsinghua Holdings subsidiary Tsinghua Unigroup, in July 2013, for about US$1.78 billion; the deal completed on 23 December 2013.
In 2014, Tsinghua Unigroup acquired RDA Microelectronics for US$907 Million. RDA Microelectronics was a fabless semiconductor company that designed, developed and marketed wireless system-on-chip and radio-frequency semiconductors for cellular, connectivity and broadcast applications.
In 2018, the company Spreadtrum Communications and RDA Microelectronics was merged and rebranded to UNISOC, in which Intel agreed to invest $1.5 billion for a 20 percent stake. The company also began working on a 5G smartphone platform with an Intel 5G modem. In February 2018, UNISOC introduced high-end smartphone SOCs with augmented reality capabilities.
UNISOC released the 5G technology platform Makalu 1.0 and the V510 5G baseband chip in February 2019. A year later, they launched the UNISOC T7520, a 5G SoC that uses of 6nm EUV advanced process technology.
In 2021, it beat HiSilicon and ranked third in the Chinese smartphone AP market share.
