Overview
USB Intelligent Interconnect Solution
Amid the growing diversity of IoT devices and surging demand for interconnectivity, efficient and reliable device connectivity has become a key challenge in product design. Traditional solutions often rely on multi-chip architectures, increasing cost and complexity. Fanlun Technology's USB solution is based on a multi-series IoT SoC platform and integrates USB 2.0 OTG and USB-Serial-JTAG as standard peripherals. It supports both Host and Device modes, enabling a single chip to cover full-scenario requirements ranging from high-speed video transmission to low-power human-machine interaction. The solution requires no additional bridge chip and supports plug-and-play and hot-swapping. It provides a complete USB ecosystem covering audio/video transmission, 4G network expansion, external storage, and human-machine interaction, greatly simplifying hardware design and improving data transmission efficiency. Whether building smart doorbell cameras, 4G IoT gateways, USB wireless flash drives, or extended displays, Fanlun's USB solution can deliver a richer functional experience at minimum BOM cost.
Applications
Industry Challenges
Fragmented Connectivity Solutions
Different peripherals often require different interface chips, making hardware design complex.
Limited Transmission Speed
Traditional serial flashing is slow and video bandwidth is often insufficient.
Difficult Multi-Device Coordination
Connecting several USB devices at once usually requires complex protocol stacks and extra management chips.
Power Management Challenges
Hot plugging and USB power control are difficult to optimize, affecting overall system stability.
High Development Barrier
Implementing USB protocol stacks is complex, and many small and mid-sized manufacturers lack specialized driver expertise.
Complex System Integration
Wireless and wired connectivity often need multiple chips working together, increasing BOM cost by more than 30%.
Difficult Debugging
Traditional JTAG debugging needs extra interfaces and complicated configuration, lengthening development cycles.
Weak Interoperability
Compatibility issues between USB devices from different vendors damage user experience.
Security Risks
USB data transmission often lacks strong security mechanisms and can be vulnerable to man-in-the-middle attacks.
Our Solution
USB Intelligent Interconnect Solution
Fanlun USB solutions provide two core architectures: the USB 2.0 OTG solution and the USB-Serial-JTAG solution. The OTG solution is based on the original manufacturer's mature chip platform and supports both full-speed (12Mbps) and high-speed (480Mbps) modes, enabling flexible switching between host and device roles. In host mode, the solution provides four core applications: UVC/UAC audio and video transmission (1080P@60FPS), 4G connectivity and Wi-Fi sharing, external storage access (up to 2TB), and HID human-machine interaction. All applications support hot plugging and USB Hub expansion. In device mode, it supports multiple standard USB device types, including UAC 2.0 audio devices, UVC video devices, MSC storage devices, HID input devices, and extended displays, and combines with Wi-Fi to achieve wired/wireless dual-mode transmission. The USB-Serial-JTAG solution is based on the original manufacturer's mature chip platform, providing dedicated USB device functionality without an external bridge chip. Firmware flashing speed is increased by 5 times, while JTAG debugging configuration is simplified. The full series of solutions is based on the original manufacturer's mature development framework, providing complete drivers and sample code, supporting LVGL graphical interfaces and the Matter interconnection standard, with full technical support from prototype to mass production.
