We are currently highlighting the GL850G USB 2.0 hub controller chip, which is brand-new, genuine, and in ample supply. We support both small-batch sample orders and large-volume orders. At the same time, we offer high-price cash buybacks for surplus GL850G chips and the full range of Genesys Logic USB 2.0 hub controller chips.

Genesys Logic (Stock Code: 6104.TWO), founded in 1997 and headquartered in Taiwan, China, is a globally renowned supplier of USB hub controller chips. The GL850G is the company’s flagship USB 2.0 hub controller, fully compliant with the USB 2.0 specification. It offers proven compatibility, lower power consumption, and a more favorable cost structure among all USB 2.0 hub solutions worldwide. Thanks to its low power consumption, low operating temperature, and minimal pin count, as well as core advantages such as independent overcurrent protection per port, the GL850G is widely used in standalone hubs, laptop docks, motherboard-integrated hubs, and monitor-integrated USB hubs.

GL850G Product Overview

The GL850G is a high-performance USB 2.0 hub controller chip launched by Genesys Logic, fully compliant with the Universal Serial Bus specification Revision 2.0. This chip expands a single upstream USB port into up to four downstream USB ports, supporting High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) data transfer, ensuring full compatibility with all types of USB devices. The GL850G boasts proven compatibility across all USB 2.0 hub solutions worldwide and is a widely adopted USB 2.0 hub chip in the market.

The GL850G integrates an 8-bit RISC processor internally, which operates control/status registers and responds to requests from the USB host. The GL850G’s firmware controls its General-Purpose I/O (GPIO) to access an external EEPROM, then responds to the host based on the custom PID and VID configured in the external EEPROM. In the absence of an external EEPROM, the default settings in the internal mask ROM will respond to the host, providing customers with great design flexibility.
