CY7C65634-48AXCT - USB 2.0 2-Port Hub | Infineon
MPN: CY7C65634-48AXCT ✓ AktifCY7C65634-48AXCT Ringkasan
A USB hub controller is an interface IC that coordinates communication between a USB host and multiple downstream USB devices. It belongs to the USB interface controller hierarchy within integrated circuits and provides the logic needed to detect attachments, arbitrate bus access, and route USB traffic. The CY7C65634-48AXCT is intended for USB 2.0 hub implementations where low system complexity and a small controller package are priorities.
The verified product information identifies the part as an EZ-USB HX2VL USB 2.0 hub controller. Its configurable GPIO resources can support hub-status or port-indicator functions, while EEPROM support allows firmware-related configuration storage. The low-power design is aimed at minimizing system power requirements in embedded USB products such as host adapters, docking equipment, and peripheral expansion systems.
The device supports USB low-speed, full-speed, and high-speed operation, as identified by distributor listings and the manufacturer product-page description. A 48-pin TQFP provides a conventional surface-mount footprint with gull-wing leads, while the 7 x 7 mm body supports compact board layouts. The exact pin names, electrical limits, clock requirements, and timing values require confirmation from the manufacturer datasheet.
Typical applications include two-port USB hubs, USB docking products, embedded host systems, and USB-to-USB expansion boards. In a two-port hub, the controller interfaces with an upstream USB host and manages downstream port attachment and status. Designers should preserve the required USB trace geometry, provide correct upstream and downstream connection routing, and verify all power and signal details against the manufacturer datasheet before layout release.
The key design consideration is the distinction between a verified feature claim and an unverified electrical parameter. This page uses the supplied manufacturer and distributor information for port configuration, package, USB speed support, packaging, and sourcing, while marking detailed technical parameters as data needed rather than estimating them. The CY7C65634-48AXCT is therefore best evaluated as a USB 2.0 hub-controller platform for compact multiport USB products.
This page combines verified distributor and manufacturer information with engineering-focused selection guidance, comparison fields, and practical USB hub design notes. It is intended to help engineers identify the correct controller and validate PCB, power, firmware, and compatibility requirements without substituting assumptions for unavailable datasheet values.

Aplikasi Biasa
CY7C65634-48AXCT patut untuk 6 aplikasis: Two-Port USB 2.0 Hub, USB Docking Station, Embedded USB Expansion, USB-to-USB Expansion Adapter, Peripheral Hub Product, Industrial USB Connectivity.
Two-Port USB 2.0 Hub
The CY7C65634-48AXCT is designed for a 2-port Single-TT hub configuration, making it a direct fit for compact USB 2.0 expansion products. Its verified support for low-speed, full-speed, and high-speed USB allows one hub controller to manage devices with different USB capabilities. The 48-pin TQFP also leaves a defined surface-mount footprint for multilayer PCBs. The design team should verify upstream and downstream routing, power distribution, and controller firmware against the manufacturer datasheet before release.
Disebarkan
USB Docking Station
A docking station can use the CY7C65634-48AXCT to provide a controlled two-port USB hub section while the rest of the dock handles display, storage, or network functions. The controller's verified USB 2.0 speed support and configurable GPIOs provide flexibility for port-status indicators and system-control signaling. Because the supplied data does not specify operating voltage, current, clocking, or thermal limits, the dock designer must obtain the official datasheet and validate the complete power and signal environment.
Disebarkan
Embedded USB Expansion
The CY7C65634-48AXCT is suitable for embedded systems that need to expand a single USB host connection into two downstream ports. Its EEPROM support can support controller configuration workflows, while configurable GPIOs can be assigned to connector status or application-specific controls. The implementation should account for upstream VBUS behavior, downstream device current, USB trace impedance, and firmware initialization. Those engineering details must be taken from the device documentation rather than inferred from the distributor snippets.
Disebarkan
USB-to-USB Expansion Adapter
The CY7C65634-48AXCT can form the basis of a compact adapter that adds two downstream USB ports to an existing host. The 2-port Single-TT configuration and USB 2.0 speed support make it appropriate for adapters intended to connect keyboards, storage, peripherals, or other USB devices. The board should preserve the required connector spacing, provide adequate VBUS distribution, and route differential USB signals as controlled impedance pairs. Exact connector and power requirements are application-specific and unavailable in the supplied data.
Disebarkan
Peripheral Hub Product
The CY7C65634-48AXCT can be integrated into a larger peripheral hub product where multiple USB functions are exposed through a common controller. Configurable GPIOs may be used for port indicators, while EEPROM support can assist configuration storage. The controller helps centralize USB hub management instead of requiring a separate hub implementation for each downstream function. Designers should confirm firmware support, connector standards, and device-current requirements before committing to this architecture.
Disebarkan
Industrial USB Connectivity
An industrial control enclosure or service interface can use the CY7C65634-48AXCT when it needs a compact two-port USB 2.0 hub for configuration, diagnostics, or service peripherals. The verified package is a surface-mount 48-pin TQFP suitable for standard PCB assembly methods. Industrial use still requires checking the manufacturer-rated temperature grade, supply tolerances, ESD requirements, and lifecycle status. The supplied data identifies the device as C-grade but does not provide the numerical temperature range.

Catatan Desain
Use controlled-impedance differential routing for every USB pair and keep the upstream and downstream traces as short and symmetric as practical. Keep the USB controller, connector protection, and power-distribution paths aligned with the manufacturer reference design when available. Because the supplied data confirms the 48-pin TQFP but not the individual pinout, do not finalize land patterns or trace connections until the official datasheet has been checked.
Validate upstream VBUS, downstream port-current limits, decoupling, and protection-device placement before production. The CY7C65634-48AXCT is a hub controller, but the supplied data does not provide its operating voltage, current consumption, or absolute electrical limits. Those values must come from the manufacturer datasheet and the attached USB devices must be checked against the complete system power budget.
Do not select a related 48-pin TQFP controller solely because the package matches. The CY7C65632-48AXC and CY7C65634-48AXC references found in the supplied data require exact comparison of pin assignment, USB signal behavior, configuration pins, clocking, and firmware. Confirm the AXCT ordering suffix, temperature grade, lifecycle status, and packaging requirements before releasing a replacement or second-source design.
Maklumat Kesediaan
The supplied data does not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. The Partstack result describes the target as lead free, but that secondary listing was not sufficient to populate the compliance field as confirmed.
