CY7C65634-28LTXCT

Controllers Overview

The CY7C65634-28LTXCT is a USB High Speed Hub Controller from the EZ-USB HX2VL series, manufactured by Infineon Technologies. It complies with the USB 2.0 specification and supports data rates of 12 Mb/s and 480 Mb/s. The device operates within a supply voltage range of 3.15 V to 5.25 V, with a typical operating current of 77.46 mA. It is housed in a 28-pin QFN package (5x5 mm) suitable for surface mount technology. The component functions as a hub controller interface, supporting serial and USB communication protocols.

Controllers Feature Summary

• Supports USB 2.0 High Speed operation at 480 Mb/s alongside Full Speed at 12 Mb/s
• Integrated hub controller functionality within the EZ-USB HX2VL family
• Compatible with standard USB interface protocols for host and peripheral connections

Controllers Applications

• USB 2.0 high-speed hub designs
• Peripheral expansion systems requiring USB connectivity
• Embedded devices needing USB interface integration

Controllers Procurement Notes

Verify the specific suffix 'CT' corresponds to the required tape and reel packaging configuration when ordering. Confirm that the 28-QFN package dimensions align with the target PCB footprint. Ensure compatibility with the 3.15 V to 5.25 V power supply requirements specified for this variant. Check moisture sensitivity level (MSL 3) handling procedures during assembly.

Controllers Selection Notes

Select this model when a dedicated USB 2.0 hub controller is required rather than a combined host/device controller. Compare against the CY7C65632 variant if different pin configurations or specific feature sets are needed. Verify that the 28-LQFP or QFN package options meet the thermal and spatial constraints of the application design.

Controllers Part Context

This component belongs to the EZ-USB HX2VL series, which provides flexible USB connectivity solutions. The CY7C65634 specifically focuses on hub control capabilities. It shares the core architecture with other members like the CY7C65632 but may differ in pinout or specific interface support. The series is designed for cost-effective USB implementation in consumer and industrial electronics.

Controllers Replacement Considerations

The CY7C65632-28LTXCT is identified as a parameter-equivalent alternative within the same product family. Verify functional differences between the 65632 and 65634 models before substitution, as they may have distinct pin assignments or feature sets despite similar packaging.
