IFXCY7C65632-28LTXC
Overview
The CY7C65632-28LTXC is a low-power USB 2.0 hub controller designed for high-performance four-port connectivity. It features a Single Transaction Translator (TT) architecture and integrates critical components such as pull-up and pull-down resistors to reduce the overall bill of materials. The controller supports both bus-powered and self-powered modes with automatic switching capabilities.
Why Choose This Part
This controller minimizes PCB footprint by integrating an internal voltage regulator and termination resistors. It offers flexible configuration via external EEPROM, allowing engineers to customize Vendor ID (VID), Product ID (PID), and the number of active downstream ports. Additionally, it provides robust power management with support for both individual and ganged port power switching.
Applications
Key Specifications
Getting Started
Designers should refer to the HX2VL development kit documentation for reference schematics and layout guidelines. Configuration of non-removable ports and custom descriptors is achieved by interfacing an external I2C EEPROM to the controller's configuration pins. Ensure the 28-QFN thermal pad is properly soldered to the ground plane to maintain stable operation within the 0 to 70 degrees Celsius range.
