Union Semiconductor, formally Shenzhen Union Semiconductor Co., Ltd., is a high-tech semiconductor company founded in 2020 and headquartered in Nanshan District, Shenzhen, China. Its official website positions the company as a developer and supplier of high-end chips, focusing on energy management, motor control, high-end electrified equipment, and smart terminal applications. It emphasizes using SoCs, smart IPMs, and power semiconductors to help customers shorten product iteration cycles.
Its product portfolio is fairly broad, covering MCUs, CPUs, ECUs, protocol chips, memory chips, FPGAs, PMU power management ICs, IGBTs, MOSFETs, and IPM integrated power modules. For MCUs, the site mentions support for Cortex-M0, M23, M3, M33, M7, and other series. Its FPGA offerings range from around 7k to 100k in scale, with packages such as QFP100, BGA256, BGA324, and BGA484. The SoC solutions highlight multi-core architecture, intelligent algorithms, high-precision ADCs, protocols, and dedicated control computing units, while the IPM products emphasize integration of drivers, sensors, and power modules.
The official website does not publish pricing, sample policies, MOQ, lead times, or distribution channel information. Given that its products are semiconductor chips and system-level solutions, actual procurement will most likely follow a project-based quotation, sample validation, volume negotiation, and custom collaboration model. Enterprise users need to contact the company through Contact us to obtain quotations and technical support.
The main advantage is its focused direction: the company builds its portfolio around growth markets such as new energy, industrial control, motor drives, and smart hardware. Its coverage from control chips to power devices and IPM modules also makes it better positioned to provide system-level solutions. Being based in Shenzhen may also make it easier to serve domestic manufacturing customers.
The downside is that the website is more presentation-oriented and lacks detailed datasheets, selection guides, development toolchains, reference designs, certifications, mass-production case studies, and supply capability information. The English content has spelling and formatting issues, which somewhat affects its professional image for overseas customers. Since the company was founded relatively recently, its ecosystem, reliability, and mass-production experience still need to be verified through real-world projects.
It is suitable for manufacturers of new energy inverters, motor control systems, industrial control equipment, smart home appliances, electric mobility products, rail transit systems, medical devices, and wearable devices that are evaluating chips or discussing custom solutions. If you are simply looking for mature general-purpose part numbers and complete public documentation, you may still need to compare it with established international vendors or more mature domestic MCU and power device suppliers.
The site is primarily a corporate showcase and its content is in English. Based on its domain and the company’s location, users in mainland China can generally access it directly. The website does not appear to offer a Chinese interface or online purchasing, so its main value is in understanding the company and its product direction, then contacting the business or technical team for further discussion.
