CY7C65630-56LTXC

Controllers Overview

The CY7C65630-56LTXC is a USB 2.0 hub controller from the EZ-USB HX2LP family, manufactured by Infineon Technologies. It supports four downstream ports and operates at High Speed (480 Mb/s) compliant with the USB 2.0 specification. The device utilizes a 56-pin QFN package and functions as a single transaction translator (1TT) hub. Electrical specifications include an operating voltage range of 3.15 V to 3.45 V, a maximum operating temperature of +70 °C, and a minimum of 0 °C. The component integrates internal regulators and termination resistors to reduce external component requirements.

Controllers Feature Summary

• Integrates four downstream ports with a single transaction translator for high-speed connectivity.
• Supports configurable power switching modes including bus-powered and self-powered configurations.
• Features integrated pull-up and pull-down resistors along with upstream and downstream termination resistors.
• Allows in-system configuration via external SPI EEPROM for VID, PID, and operational parameters.

Controllers Applications

• Standalone USB hubs
• Motherboard hubs
• Docking stations

Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications, as this specific part number may be discontinued. Ensure storage conditions account for moisture sensitivity levels prior to soldering.

Controllers Selection Notes

Select this model when four downstream ports are required within a compact footprint. Verify that the application environment remains within the specified commercial temperature range of 0 °C to +70 °C. Consider industrial-grade alternatives if extended temperature ranges are necessary.

Controllers Part Context

This component belongs to the EZ-USB HX2LP low-power USB 2.0 hub controller family. It shares pin compatibility with the CY7C65640 series while offering distinct port configurations. The family emphasizes reduced bill-of-materials through integrated passive components and regulatory compliance features.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers include CY7C65634-48AXC and CY7C65634-48AXCT. These alternatives maintain compatibility within the USB interface IC category but require verification of specific electrical and mechanical differences against original design constraints.
