CY7C65630-56LTXIT

Controllers Overview

The CY7C65630-56LTXIT is a USB 2.0 hub controller from the EZ-USB HX2LP family, manufactured by Infineon Technologies (formerly Cypress). It features four downstream ports and a single transaction translator within a 56-pin QFN package. The device supports high-speed operation at 480 Mb/s and complies with USB 2.0 specifications. It integrates an internal regulator for reduced cost and requires a single power supply. Configuration is handled via external SPI EEPROM, allowing customization of VID/PID/DID, port counts, and power settings.

Controllers Feature Summary

• Integrates four downstream ports with a single transaction translator for efficient data routing between high-speed upstream and full/low-speed downstream devices.
• Supports both bus-powered and self-powered modes with configurable overcurrent detection and port power switching control.
• Includes integrated pull-up/pull-down resistors and termination resistors to minimize external component requirements.
• Features programmable port status indicators with automatic and manual LED control modes.

Controllers Applications

• Standalone USB hubs
• Motherboard hubs
• Docking stations and port replicators

Controllers Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range compliance if required by your design environment. Confirm the 'T' suffix corresponds to tape-and-reel packaging as per standard Infineon ordering conventions. Ensure the external SPI EEPROM matches the voltage levels supported by the device's serial interface pins.

Controllers Selection Notes

Select this model when four downstream ports are required in a compact footprint. Compare against the CY7C65620 if only two ports are needed. Consider the CY7C65642 if lower power consumption or a smaller 28-pin package is preferred over the 56-pin form factor. Verify compatibility with existing host controllers regarding high-speed negotiation.

Controllers Part Context

This component belongs to the EZ-USB HX2LP low-power USB 2.0 hub controller family. It is functionally compatible with the TetraHub CY7C65640 series but offers optimized power characteristics. The device serves as a fixed-function hub controller, eliminating the need for complex firmware development compared to programmable USB controllers.

Controllers Replacement Considerations

CY7C65640-56LTXIT is a fit, form, and function compatible alternative within the TetraHub family. CY7C65632-28LTXCT offers similar functionality in a smaller 28-pin package but may require layout adjustments due to pinout differences.
