CY7C65620-56LTXIT

Controllers Overview

The CY7C65620-56LTXIT is a USB 2.0 hub controller from the EZ-USB HX2LP family, manufactured by Infineon Technologies (formerly Cypress). It supports two downstream ports and features a single transaction translator for high-speed operation at 480 Mb/s. The device operates on a single 3.3 V power supply with an internal regulator and functions within a temperature range of -40 °C to +85 °C. It draws up to 163 mA during operation and utilizes a 56-pin QFN package.

Controllers Feature Summary

• Integrates upstream and downstream transceivers, serial interface engine, and hub control logic
• Includes built-in pull-up and pull-down resistors to reduce external component requirements
• Supports configuration via external SPI EEPROM for VID, PID, and port settings
• Features integrated port status indicators with automatic and manual control modes

Controllers Applications

• Standalone USB hubs
• Motherboard hubs
• Monitor hubs
• Advanced port replicators
• Docking stations

Controllers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status through current manufacturer datasheets or FIT reports before procurement. Ensure compatibility with existing system designs regarding pin assignments and power requirements.

Controllers Selection Notes

Select this model for applications requiring exactly two downstream ports. Consider the CY7C65630 if four downstream ports are needed. Verify that the host system supports USB 2.0 High-Speed protocols. Ensure the design accommodates the required external components for power switching and overcurrent detection as specified in the datasheet.

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 CY7C65640 and CY7C65640A series but offers a reduced port count. The device is designed for space-constrained applications requiring efficient power management and simplified PCB layouts.

Controllers Replacement Considerations

The CY7C65630 serves as a direct functional substitute for designs requiring additional downstream ports while maintaining pin compatibility.
