CY7C65642-28LTXC

Controllers Overview

The CY7C65642-28LTXC is a USB 2.0 hub controller from the EZ-USB™ HX2VL family, featuring four downstream ports with dedicated transaction translators for high performance. It operates at speeds up to 480 Mbps and supports Full Speed (12 Mbps) and Low Speed (1.5 Mbps) devices. The device integrates an internal regulator requiring a single 5 V supply, though external regulation is supported. It includes a 2K ROM and 64-byte RAM MCU, configurable VID/PID via EEPROM, and status indicators. Operating conditions range from 0°C to +70°C in a 28-pin QFN package.

Controllers Feature Summary

• Integrates four independent transaction translators to maximize bandwidth for full-speed and low-speed devices without multiplexing overhead.
• Features highly integrated power management with an internal regulator, eliminating the need for external voltage conversion components.
• Supports flexible configuration of port numbers, removable status, and power switching modes through external EEPROM or pin strapping.
• Includes built-in overcurrent detection and dual-mode (automatic/manual) LED indicators for each downstream port.

Controllers Applications

• Docking stations
• Standalone hubs
• Monitor hubs
• Multi-function printers
• Gaming consoles

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and temperature grade. Confirm that the required configuration data matches the default mask ROM settings or prepare the necessary external EEPROM if custom VID/PID values are needed for the final product implementation.

Controllers Selection Notes

Select this component when designing a cost-effective USB 2.0 hub requiring four downstream ports with high-performance transaction translation. It is suitable for applications where minimizing bill-of-material costs is critical due to its integrated regulators and resistors. Ensure the design accommodates the 28-pin QFN thermal requirements and provides the necessary 12-MHz crystal or oscillator clock input.

Controllers Part Context

This part belongs to the EZ-USB™ HX2VL series, which represents Infineon's next-generation low-power USB 2.0 hub controllers. The HX2VL family is designed to replace previous generations like the HX2 and HX2LP, offering improved power efficiency and higher integration levels while maintaining compatibility with standard USB 2.0 specifications.
