CH334H Description

Short technical summary and product information.

The WCH CH334H is a high-performance 4-port USB 2.0 hub controller featuring MTT (Multi-Transaction Translator) support. This architecture allows each port to handle transactions concurrently, optimizing bandwidth utilization for demanding applications.

 

Key specifications include 4 USB ports with a maximum speed of 480 Mbps. The controller operates within an industrial temperature range of -40°C to 85°C, making it suitable for robust environments. It is designed for industrial PC motherboards, embedded USB hubs, and high-performance peripherals.

 

This highly integrated chip includes an internal USB PHY, LDO, and a high-precision clock, significantly reducing the need for external components. It operates on a 3.3V supply voltage, with an internal LDO capable of converting USB bus power if necessary. Avoid this component for applications requiring USB 3.0 or higher speeds.
