CY7C65631-56LTXC

Controllers Overview

The CY7C65631-56LTXC is a low power USB 2.0 hub controller from Infineon Technologies, part of the EZ-USB HX2LP Lite family. It supports up to four downstream ports with a single transaction translator and operates at high speed data rates of 480 Mb/s. The device functions within a supply voltage range of 3.15 V to 3.45 V and draws 110 mA during operation. Designed for surface mount applications, it utilizes a 56-pin QFN package suitable for industrial and consumer environments operating between 0 °C and +70 °C.

Controllers Feature Summary

• Integrates upstream and downstream transceivers, USB Serial Interface Engine, Hub Control logic, and Transaction Translator on a single chip.
• Includes internal regulators and integrated pull-up/pull-down resistors to reduce external component requirements.
• Supports in-system configuration via external SPI EEPROM for customizable VID, PID, port counts, and power settings.
• Features dual-color port status indicators (green and amber) with configurable automatic or manual control modes.

Controllers Applications

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

Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for moisture sensitivity handling requirements prior to assembly. Ensure the specific ordering suffix matches the required temperature grade and packaging specifications.

Controllers Selection Notes

Select this model when a compact four-port solution with a single transaction translator is required. Verify that the application environment remains within the specified 0 °C to +70 °C operating temperature range. Confirm compatibility with the host system's USB 2.0 High Speed requirements and available power budget.

Controllers Part Context

This component belongs to the EZ-USB HX2LP Lite family, designed as an ultra-low power alternative to previous generations. It maintains pin-for-pin compatibility with the TetraHub series while offering reduced power consumption and simplified integration through built-in passive components.

Controllers Replacement Considerations

The CY7C65634-48AXC is listed as a potential replacement option by distributors. Verify functional equivalence regarding port count and transaction translator architecture before substitution.
