Nanjing Qinheng Microelectronics Co., Ltd. was established in 2004 and is an interface chip and full-stack MCU chip company. Qinheng focuses on the research of connection technology and MCU core, and adopts a full-stack R&D model based on the underlying IP R&D chip design and underlying common software development. It mainly uses self-developed processor IP and transceiver IP modules to integrate and build USB, Ethernet, Bluetooth and other interface chips, as well as connection/interconnection/wireless full-stack MCU microcontrollers. The technology involves "perception, control, connection, and cloud gathering": ADC analog detection, MCU intelligent control and motor drive algorithm, HID human-computer interaction, Ethernet/Bluetooth-LE network communication, UART/USB/PD/PCI/CAN and other interface communications, Internet of Things protocols and cloud services. We are committed to providing customers with chips and solutions that connect everything and communicate with each other.
