USX2064T/M2

Controllers Overview

The USX2064T/M2 is a USB 2.0 hub controller IC manufactured by Microchip Technology, designed for high-performance and ultra-low-power applications. It features four downstream ports compliant with the USB 2.0 specification and utilizes MultiTRAK technology to provide one transaction translator per port. The device operates on a single external 3.3 V supply source, supported by internal regulators providing a 1.2 V core voltage. It includes an onboard 24 MHz crystal driver or supports external 24/48 MHz clock inputs. The component offers 4 kV HBM ESD protection and supports self- or bus-powered operation. It is housed in a space-saving 36-pin QFN package measuring 6x6 mm.

• PortSwap enables programmable USB differential-pair pin locations to align signal lines directly with connectors.
• PHYBoost offers programmable USB signal drive strength with four-level resolution to recover signal integrity.

Controllers Applications

• Mobile PC Docking Stations
• LCD Monitors and TVs
• PC Motherboards
• Gaming Consoles
• Point-of-Sale (POS) Systems

Controllers Procurement Notes

Verify the specific ordering suffix against official documentation to ensure correct packaging and temperature ratings. Confirm current availability status as distribution channels may update stock levels frequently. Ensure compliance with RoHS standards and check for any recent Product Change Notifications regarding assembly or material changes before finalizing procurement orders.

Controllers Selection Notes

Select this component when designing space-constrained systems requiring scalable USB expansion from two to four ports. Consider its integrated power management features for individual or ganged downstream port control. Evaluate the need for customizable vendor and product IDs for OEM integration. Verify that the 3.3 V single-supply architecture aligns with the target system's power budget and thermal constraints.

Controllers Part Context

The USX2064T/M2 belongs to the USX2064 family of versatile, cost-effective, and power-efficient USB 2.0 hub controllers. This family shares a common 36-pin package, allowing for scalable port expansion across different models within the series. The design emphasizes small footprint solutions without compromising performance, making it suitable for consumer and mobile applications where board space is limited.

Controllers Replacement Considerations

Consult the official Microchip USX2064 Development Tool Selector for verified substitute part numbers. Ensure any replacement maintains compatibility with the 36-pin QFN package and USB 2.0 specifications. Verify that alternative components support the same MultiTRAK technology and configuration options required for the existing design.
