CY7C65620-56LTXC - 2-Port USB 2.0 Hub Controller | Infineon
N.º da peça: CY7C65620-56LTXC ✓ AtivoCY7C65620-56LTXC Visão geral
A USB hub controller is an interface integrated circuit that manages one upstream USB connection and multiple downstream ports. It belongs to the hierarchy of USB interface controller, interface IC, and integrated circuit. Rather than duplicating full host-controller logic in every peripheral, a hub controller centralizes port enumeration, power-management coordination, status signaling, and downstream traffic management across a USB 2.0 peripheral or host system.
The CY7C65620 provides two downstream ports and a 480 Mbps high-speed data rate. Its 3.45 V operating capability aligns with 3.3 V USB transceiver implementations. GPIO configuration allows product-specific behavior, LED indicators can report port activity or status, and EEPROM support enables configuration information to be retained or supplied by the system designer. These features are useful when a product requires a compact two-port hub without using a larger external hub implementation.
The controller belongs to the EZ-USBTM HX2LP family and is identified as a two-port Single-TT hub solution. The 56-QFN 8 x 8 mm package supports compact integration but requires careful exposed-pad thermal and layout management. The product is available in bulk packaging according to the manufacturer listing. Infineon markets the device with configuration, ordering, parameter, and datasheet information on its official component page.
Typical applications include USB 2.0 peripheral hubs, embedded host systems, docking equipment, printer or storage interfaces, and industrial control panels that need more than one USB connection. In these systems, the controller can reduce the number of dedicated USB interface blocks while preserving high-speed signaling. Firmware and board validation remain essential because downstream-port behavior, enumeration, and indicator management must match the complete product architecture.
Designers should place the USB differential pairs on a controlled-impedance PCB, keep the exposed pad and power connections compliant with the manufacturer layout guidance, and validate both full-speed and high-speed operation. Power budgeting, inrush behavior, cable faults, and LED-current limits should be checked before production release. The available public snippets confirm the core USB and package characteristics but do not expose every electrical limit, so the manufacturer datasheet remains the controlling design reference.
This page consolidates verified manufacturer and distributor information, price context, package details, and design-oriented guidance. It also distinguishes confirmed drop-in candidates from unrelated USB interface devices, helping engineers evaluate replacement options without confusing functional similarity with true pin-to-pin compatibility.

Aplicações típicas
CY7C65620-56LTXC é adequado para 6 aplicaçãos: Compact USB 2.0 Peripheral Hub, Embedded Host USB Expansion, Industrial Docking Station, Printer and Storage Interface Hub, Industrial Control Panel, USB Test and Configuration Fixture.
Compact USB 2.0 Peripheral Hub
The CY7C65620-56LTXC fits a compact two-port USB 2.0 hub because it integrates downstream-port control with a 480 Mbps high-speed interface. One upstream connection can therefore serve two peripheral ports without adding two independent host interface blocks. Configurable GPIOs and LED indication support port-status or product-specific signaling, while EEPROM support permits configuration information to be retained. The 56-QFN 8 x 8 mm package helps limit board area, although exposed-pad layout and USB differential routing require careful implementation.
Recomendado
Embedded Host USB Expansion
The CY7C65620-56LTXC can expand USB connectivity in an embedded host system that already has one upstream USB interface. Its two-port Single-TT hub architecture and 480 Mbps high-speed capability allow keyboards, storage devices, service interfaces, or other peripherals to share the host connection. The 3.45 V operating capability and 3.3 V transceiver supply align with conventional USB 2.0 signaling environments. Product firmware must still implement enumeration, suspend, resume, and fault-handling behavior expected of the complete system.
Recomendado
Industrial Docking Station
A two-port industrial docking system can use the CY7C65620-56LTXC to consolidate USB 2.0 peripheral connections behind one upstream port. The 480 Mbps high-speed rate supports storage and data-transfer use cases, while configurable GPIOs can assist with port-enable, fault, or activity functions and LED indication can expose connection status to the operator. The 8 x 8 mm QFN package supports dense terminal equipment, but designers should verify industrial temperature requirements and use the appropriate grade rather than assuming C-grade coverage.
Recomendado
Printer and Storage Interface Hub
The CY7C65620-56LTXC is suitable for systems that need to share one upstream USB 2.0 connection between a printer, removable storage device, and another peripheral. Its two downstream ports and 480 Mbps high-speed signaling provide a practical bandwidth ceiling for this use, while bus-powered-device requirements must be evaluated separately at the system power level. LED indication can communicate port status, and EEPROM support can assist configuration. Enumeration behavior and simultaneous high-speed device operation should be verified during board and firmware validation.
Recomendado
Industrial Control Panel
In an industrial control panel, the CY7C65620-56LTXC can manage two USB 2.0 service or peripheral connections behind a single host port. The controller's configurable GPIO resources can participate in port-enable, reset, or status logic, and its LED support can provide local operating feedback. The 56-QFN package is practical for compact controller boards, while USB high-speed operation at 480 Mbps is adequate for configuration links and moderate data-transfer peripherals. Production designs should verify temperature grade, ESD protection, grounding, and cable-port survivability requirements.
Recomendado
USB Test and Configuration Fixture
The CY7C65620-56LTXC can support a USB 2.0 test fixture that exposes one upstream host connection through two downstream ports. This arrangement is useful for firmware recovery, peripheral configuration, manufacturing test, and field-service access. Its 480 Mbps high-speed operation and configurable GPIOs support the hub function and fixture-specific status signaling, while LED indication can simplify operator diagnostics. The 3.3 V transceiver supply is compatible with conventional USB signaling, but fixture power must be designed to avoid excessive inrush and ensure correct downstream-port power sequencing.

Notas de projeto
Route the USB differential pairs as a controlled-impedance pair with continuous reference-plane support and minimize branch stubs, vias, and right-angle transitions. Keep the USB transceiver and connector-related return paths short, and observe the manufacturer's placement and routing guidance for the 56-QFN device. The supplied sources confirm the 8 x 8 mm QFN package but do not provide the complete reference layout, so engineers should not infer trace dimensions or spacing without the manufacturer documentation.
Design the 3.3 V transceiver supply and the controller's operating supply for the voltage range and current limits in the manufacturer datasheet. USB downstream-port power, inrush, and bus-powered-device current are separate from the controller's own supply budget and must not be inferred from the 3.45 V operating value. Validate suspend and resume current, hot-plug behavior, capacitor selection, and startup sequencing with the complete board configuration.
The 56-QFN 8 x 8 mm package concentrates heat into a limited footprint and exposed pad. Follow the manufacturer's land pattern, exposed-pad connection, solder, and copper requirements, then evaluate junction temperature under the highest expected USB traffic and ambient conditions. The supplied search data does not include thermal resistance or power dissipation, so no thermal value is asserted here and the manufacturer datasheet must control the thermal design.
Do not treat every USB interface IC as a hub-controller substitute. The verified alternatives are Infineon EZ-USBTM-family candidates with a matching 56-QFN footprint; generic USB-to-serial bridges and USB-to-UART devices listed by generic comparison sites do not provide equivalent hub functionality. Before replacing the CY7C65620-56LTXC, verify every GPIO assignment, LED behavior, EEPROM interface, port-power control, enumeration sequence, and firmware dependency.
