CY7C65630-56LTXAT

Controllers Overview

The CY7C65630-56LTXAT is a Hi-Speed USB Hub Controller from the HX2LP series, manufactured by Infineon Technologies. It operates at a maximum clock frequency of 24 MHz and supports data rates up to 480 Mb/s in accordance with USB 2.0 standards. The device functions as a hub controller interface IC, utilizing SPI and USB interfaces for communication. It requires a single 3.3 V power supply and draws approximately 231 mA during operation. The component is housed in a QFN-56 package with 56 terminals, designed for surface mount installation. It is rated for an operating temperature range from -40 °C to +85 °C.

Controllers Feature Summary

• Supports High-Speed (HS) USB 2.0 connectivity with integrated hub controller functionality
• Interfaces via SPI protocol for host control and configuration
• Operates on a standard 3.3 V power supply rail

Controllers Applications

• USB hub implementations in consumer electronics
• Interface adapters and docking stations
• Mobile device accessory connections

Controllers Procurement Notes

Verify the exact suffix 'A' against official Infineon documentation to confirm if it denotes a specific tape-and-reel variant or packaging difference compared to the 'T' suffix. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the source document explicitly lists this part number to avoid confusion with similar HX2LP family members.

Controllers Selection Notes

Select this component when a compact, low-power USB 2.0 hub controller is required for designs constrained by the QFN-56 footprint. Verify that the system design can accommodate the 24 MHz clock requirement and 3.3 V logic levels. Compare pinout compatibility with existing PCB layouts if replacing older hub controllers. Ensure thermal management strategies align with the specified operating temperature range.

Controllers Part Context

This part belongs to the EZ-USB HX2LP family of USB hub controllers, which are designed for low power consumption and small form factors. It serves as a bridge between USB hosts/peripherals and downstream USB devices, managing bandwidth and enumeration within a hub topology. The HX2LP series is distinct from the higher-performance HX3 or HX2 families.

Controllers Replacement Considerations

Publicly confirmed direct substitutes include other variants within the HX2LP family such as the CY7C65630-56LTXI or CY7C65630-56LTXIT, provided pinouts and electrical characteristics match exactly. Cross-family replacements require significant schematic and firmware redesign.
