Unisoc

Unisoc Technologies Co., Ltd., commonly known as Unisoc, is a Chinese fabless semiconductor company that designs system-on-chip (SoC) solutions for mobile devices and connected products. It is a subsidiary of the state-backed technology group Tsinghua Unigroup and is headquartered in Shanghai, China. Unisoc focuses on mobile application processors, baseband/modem chips, and IoT-oriented SoCs, with products intended for smartphones, feature phones, tablets, wearables, and other connected devices.

The company traces its origins to the 2018 merger of Spreadtrum Communications and RDA Microelectronics, two Chinese chip designers that specialized in wireless communications technologies. The merger created a single entity aimed at competing in the global mobile semiconductor market. As a fabless company, Unisoc designs chips and relies on external semiconductor foundries for manufacturing, while maintaining research and development and customer support operations in China and other regions.

Products and market emphasis: Unisoc’s portfolio covers 2G/3G/4G and 5G-capable mobile SoCs, along with chips for Internet of Things applications and AI-enabled devices. The firm emphasizes cost efficiency, power efficiency, and broad connectivity to serve price-sensitive segments in China, South Asia, Africa, and other emerging markets. While it does not reach the market share of larger incumbents in flagship smartphones, Unisoc remains a notable supplier for mid- and entry-level devices and for various IoT platforms.

Overall, Unisoc represents China’s ongoing efforts to develop independent mobile semiconductor design capabilities, focusing on affordable, energy-efficient solutions across mobile, IoT, and related applications.
