Since 2021, it has been the fourth largest mobile processor manufacturer in the world, after MediaTek, Qualcomm and Apple, with 13% of global market share in 2024.[2][3]
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.[4][5] 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.[6]

Perspective
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.[7]
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;[8] the deal completed on 23 December 2013.[9]
In 2014, Tsinghua Unigroup acquired RDA Microelectronics for US$907 Million.[10] 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.[11][12] In February 2018, UNISOC introduced high-end smartphone SOCs with augmented reality capabilities.[13]
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.[14]
In 2021, it beat HiSilicon and ranked third in the Chinese smartphone AP market share.[15]
Main products
Currently, UNISOC's main products include mobile system-on-chips, baseband chips, AI chips, radio frequency chips, and other communication, computing, and control chips, which are widely used in consumer electronic devices such as smartphones, tablets, and smart wearables.
