What Nanjing Qinheng Microelectronics Co does

Nanjing Qinheng Microelectronics Co (legal name 南京沁恒微电子股份有限公司, brand WCH/WinChipHead) is a privately-held, fabless integrated circuit design company founded in 2002 and headquartered in Nanjing, China. The company designs and sells USB interface chips, Bluetooth Low Energy chips, Ethernet controllers and PHYs, USB PD / Type-C controllers, and a broad portfolio of microcontrollers built around its proprietary Qingke (青稞) RISC-V processor core family — now in its fifth generation (V2A through V5F). Its technical differentiator is full vertical integration from PHY transceivers through link-layer controllers to protocol stacks, combined with self-developed RISC-V cores, eliminating third-party IP licensing and enabling tight hardware-software co-design.

The product catalog spans hundreds of variants across general-purpose MCUs (CH32V003/103/203/303/307/317/407), Bluetooth wireless MCUs/SoCs (CH572/573/582/583/585/592/596), motor-control MCUs with integrated pre-drivers (CH32M series), USB3.0 HUB and interface MCUs (CH569/CH634/CH637/CH32H417), wireless-charging SoCs, and legacy ARM Cortex-M and 8-bit lines. The company reports annual USB chip and Qingke-core chip volumes each exceeding 100 million units, deployed across more than 10,000 companies worldwide in industrial control, IoT/networking, and computer/mobile peripheral applications.

Revenue is generated through B2B hardware sales of chips via direct sample-request channels, regional distributors, and a community-supported sales (BBS) channel. Pricing is quote-based and not publicly listed. The company has been recognized as a National Specialized and Innovative 'Little Giant' Enterprise (MIIT), a National High-Tech Enterprise, and a National Intellectual Property Advantage Enterprise. It is founder-owned, has not raised disclosed outside capital, and maintains R&D collaborations with Southeast University, Hefei University of Technology, and Soochow University to support its RISC-V talent pipeline.
