Nanjing Qinheng Microelectronics Co., Ltd.

Nanjing Qinheng Microelectronics Co., Ltd. focuses on connectivity technology and microprocessor research and is an IC design company that designs chips based on self-developed professional interface IP and microprocessor IP. We are committed to providing customers with chips and solutions for the interconnection of everything, up and down, and its main products include USB/Bluetooth/Ethernet interface chips and connected/interconnected/wireless MCUs, which focus on connectivity, networking and control.

SoC and MCU chips can usually be decomposed into several lower-level IP components. For example, the first step in designing a USB network card chip is to purchase or develop the 3 major components of USB PHY and controller, Ethernet PHY and MAC, and processor core. Different from the quick and trouble-free route of outsourcing PHY or processor IP component technology license and then assembling and designing chips, we insist on long-termism based on the consideration of performance, cost and autonomy, and has been continuously laying out the self-research of key IP components for many years, focusing on the tracing of the origin and the bottom layer construction.Our IP system brings flexibility in chip architecture. Compared with the black box of outsourced components, self-developed underlying components are conducive to integrated articulation and optimization, improve overall performance and efficiency, reduce power consumption, reduce size, and have a sustainable development path and long-term marginal cost advantage.

Our advantage: Solid foundation, core autonomy, overall synergy 

Based on our specialization in connectivity and networking, we conducted dedicated to research on key and common technologies of interface chips and MCUs especially suited for this era of interconnectivity and networking everywhere. These include microprocessor cores, professional interfaces such as USB/Bluetooth/Ethernet, and other IP modules. This combination is referred to as "one core and three interfaces" in short.

Self-developed interface IP: highly optimized system-level interface chips provide efficient connectivity solutions for a connected world

Connection technologies include PHY physical layer transceivers, MAC or link controllers, protocol stacks or operating system drivers, interconnection application layers, etc. Among them, the physical layer is located at the bottom layer of the connection and is usually implemented by mixed digital and analog technologies such as SerDes or RF transceivers, ultra-high-speed ADCs, and DSP-level baseband algorithms. It is the "root" technology of the connection. Based on years of research on connection, Qinheng's independent IP system covers and passes the vertical data chain composed of transceiver, controller and protocol stack, and the strong coupling integration design improves the synergy of software and hardware, reduces power consumption, and improves efficiency and compatibility. The cross-combination of professional interfaces and the matrix combination of professional interfaces and core form the verticalized products such as PHY chip, controller chip, protocol stack chip and interface conversion chip, which realize the function expansion or bridge conversion of USB, Bluetooth and Ethernet, and adapt to the diversified industrial application requirements with the multi-level product structure and professional performance.

Self-developed IP: a flexible combination of multi-level cores and professional peripherals to form a wide range of MCUs and system-level SoC

Our company's self-developed “core” technology includes QingKe RISC-V and early E8051 core, after more than 10 years of research and development and iteration, realize the core freedom, part of the RISC-V chip has been mature commercial at least 5 years. We stand at the forefront of the RISC-V industry and is committed to promoting the landing and development of RISC-V in the MCU industry, and has published the key technologies of the QingKe RISC-V series of mass-production chips at the RISC-V World Conference CHINA 2021.

QingKe core is based on the concept of RISC-V eco-compatibility and optimized expansion. We incorporate technologies like VTF to accelerate interrupts, expand the protocol stack and support low-power application instructions, and streamline debug interfaces. MCUs and high-speed interface SoCs equipped with QingKe cores avoid dependence on third-party chip technology, reduce dependence on offshore software platforms and application ecosystems, and eliminate the licensing fees and per-chip commission fees for outsourced IP technology, saving costs for the industry chain and customers. Our company's flexible matrix combination of multi-layer cores with specialized peripherals such as high-speed USB, PD, Ethernet, BLE and other peripherals, focusing on application optimization and overall synergy, enables MCUs and SoCs to excel in connectivity scalability, performance, power consumption, integration and other aspects.

Combining hardware and software to break through the barriers of device connectivity, promoting seamless communication and cross-platform mobility

In addition to the chip design team, hardware, and embedded software teams specialized in lower-level development, our company also has a system and software team specializing in upper-level deployments like computers, servers, and the Core Cloud platform. The team specializes in the development of underlying core drivers, communication libraries, and APP application tools for various operating systems and platforms such as Windows, Linux, macOS, Android, iOS, and WeChat. We utilize virtualization technology to enable seamless cross-platform connectivity and application migration, facilitating the transformation of offline devices into connected devices, and enhancing the added value of end products. Furthermore, we provide customers with comprehensive system-level solutions.
 

Cumulate & Perfect 

After years of dedicated efforts, our company has provided more than 100 chip categories and technical solutions to customers. WCH chips are integral components found in products from tens of thousands of companies worldwide. Each year, over 100 million devices establish connections through them. Boasting over 100 million cumulative shipments of its USB series chips, our company also sells more than 100 million units of its QingKe RISC-V core-based chips annually. Additionally, our self-service programming platform programs MCUs with target firmware for clients on the order of a million units monthly.

Thanks to the autonomy and overall synergy of the underlying components, WCH chips have reduced the number of internal links, lowered power consumption and shrunk in size. For example, the Bluetooth chip CH585 with integrated high-speed USB is only QFN3*3, the USB3.0 HUB chip CH634F is only QFN4*4, and the CH32M007E with built-in high-voltage LDO and motor pre-driver is only QFN3*3. While the packages are shrunken, the cost is optimized and the high-frequency characteristics are improved.

Qinheng places great emphasis on investment in research and development, acquiring multiple independent intellectual property rights through innovation, including patents, integrated circuit layout design rights, software copyrights, and more. Our company has been recognized as a high-tech enterprise, a national-level specialized and new "small giant" enterprise, a national intellectual property advantageous enterprise. We have also registered international trademarks in many countries and regions such as the United States, United Kingdom, Germany, Japan, and South Korea.

We never forget the essence and social significance of our enterprise. As we grow, we strive for mutual growth with our staff. We also adhere to a healthy market-oriented operation and use high-quality, professional chips to assist our customers in providing society with better products.
