CY7C65620-56LTXCT - 2-Port USB 2.0 Hub Controller | Infineon
N.º da peça: CY7C65620-56LTXCT ✓ AtivoCY7C65620-56LTXCT Visão geral
A USB hub controller is an interface integrated circuit that manages traffic between one upstream USB host connection and multiple downstream USB ports. Within the device hierarchy, the CY7C65620 belongs to the class of USB interface controllers, bus controllers, and broader interface integrated circuits. Its two-port single-TT configuration provides a practical way to consolidate USB peripheral connections while keeping host-interface decoding and downstream-port control in one dedicated component.
The principal features supported by the manufacturer information are USB 2.0 operation, two downstream ports, single-TT topology, configurable GPIOs, LED indicator support, and EEPROM support. The 56-QFN package has 56 no-lead terminals and a square 8 mm by 8 mm body. These characteristics make the controller appropriate for compact external hubs, embedded USB port expanders, docking equipment, and industrial computers whose downstream ports require controlled bus transactions.
The controller is intended to operate with a USB host and downstream USB peripherals while supporting configuration through general-purpose I/O and optional nonvolatile hub metadata. Configurable GPIOs provide a way to connect device-control signals such as port indicators or system-control functions. EEPROM support can assist systems that require persistent configuration data, while the dedicated port-control capability remains distinct from a passive USB power hub.
Typical applications include two-port desktop USB hubs, printer and storage adapters, embedded systems requiring USB port expansion, industrial control panels, and test equipment that needs repeatable downstream-port behavior. Board layout must preserve the 56-QFN land pattern, adequate exposed-pad thermal treatment if the package configuration provides one, and the decoupling and signal-routing practices specified by the manufacturer datasheet.
When choosing a replacement, verify the exact package, terminal arrangement, temperature grade, and shipping format rather than relying only on the controller family name. The CY7C65620-56LTXC, CY7C65620-56LTXI, and CY7C65620-56LTXIT share the controller and 56-pin QFN format but use different ordering formats. Confirm the appropriate ordering code against production assembly requirements.
This page consolidates the manufacturer ordering details, package information, practical application guidance, comparison parameters, and verified drop-in ordering options into a design-oriented resource. It also distinguishes electrical controller compatibility from assembly-format selection so engineers can make a traceable replacement decision.

Aplicações típicas
CY7C65620-56LTXCT é adequado para 6 aplicaçãos: Compact Two-Port USB Hub, USB Docking Station, Embedded USB Port Expander, Industrial Control Panel Hub, Printer and Storage Adapter, USB Test and Measurement Adapter.
Compact Two-Port USB Hub
The CY7C65620-56LTXCT fits a compact two-port USB hub because it integrates the USB 2.0 hub-control function for two downstream ports in a single 56-QFN device. Its single-TT topology provides a defined downstream-bus arrangement, while configurable GPIOs can support port-status or user-interface signals. The controller is more appropriate than a passive hub when downstream traffic, port indication, or configuration behavior must be actively managed. Use the manufacturer pin definitions and application circuit to route high-speed USB pairs, connect the required EEPROM interface, and select the power-delivery architecture for the attached loads.
Recomendado
USB Docking Station
A USB docking station can use the CY7C65620-56LTXCT to add two controlled USB 2.0 downstream ports while retaining a compact board footprint. The controller’s two-port single-TT configuration limits the required downstream topology, and its configurable GPIOs can assist with port indicators or system-control functions. EEPROM support can also support persistent device configuration when the system requires it. The design must still address connector data routing, port power switching, fault protection, and the exact 56-QFN land pattern shown in the manufacturer package documentation.
Recomendado
Embedded USB Port Expander
The CY7C65620-56LTXCT can expand an embedded platform with two controlled USB 2.0 ports when the enclosure and main board have space for only a limited connector set. Because the device is a dedicated two-port single-TT hub controller, it supports active USB traffic management instead of merely distributing connector power. Its configurable GPIOs provide additional integration flexibility for indicators or platform-control signals, while EEPROM support can serve designs needing retained configuration. Validate the controller’s operating limits, power requirements, and routing guidance against the exact manufacturer datasheet.
Recomendado
Industrial Control Panel Hub
The CY7C65620-56LTXCT is suitable for an industrial control panel that needs two USB 2.0 service or peripheral ports with controlled bus behavior. The dedicated two-port controller architecture helps avoid the limitations of a passive power hub, while configurable GPIOs can be connected to panel indicators or supervisory control signals. EEPROM support may be useful for storing configuration parameters in equipment that must retain setup information. The enclosure, grounding, port protection, and thermal environment must be evaluated separately because the component’s C-grade designation and detailed electrical limits must be checked against the deployment requirements.
Recomendado
Printer and Storage Adapter
The CY7C65620-56LTXCT can serve as the USB interface controller in a combined printer or storage adapter that exposes two USB 2.0 connections. A single-TT two-port arrangement provides a straightforward downstream topology for peripherals sharing the same host interface, while GPIO configuration can support connection indicators or mode-control signals. The design should use the manufacturer’s recommended decoupling and signal-layout practices to preserve USB signal quality, particularly around the 56-QFN terminals and any exposed-pad connection. Power for storage loads should be designed separately because the hub controller manages data traffic rather than supplying downstream-port power.
Recomendado
USB Test and Measurement Adapter
A test or measurement adapter can use the CY7C65620-56LTXCT to provide two USB 2.0 device connections to a host computer while adding status and configuration signaling. The controller’s dedicated hub function offers more deterministic downstream-bus behavior than a passive connector splitter, and its configurable GPIOs can be linked to instrument-state or diagnostic indicators. EEPROM support can retain configuration when repeatable setup is required. Engineers should verify the detailed timing, power, and operating-temperature requirements in the manufacturer datasheet, then follow its high-speed differential-pair routing and decoupling guidance.

Principais diferenciais
- Dedicated two-port USB hub control (vs CY7C65620-56LTXC)

- Exact C-grade production ordering option (vs CY7C65620-56LTXIT)
Notas de projeto
Route USB high-speed differential pairs as controlled impedance, continuous references, and short symmetrical paths to the connectors. Use the manufacturer pin-description table and layout guidance to determine which 56-QFN terminals belong to each interface. Keep the USB data pairs away from switching-node and power-converter return currents, and avoid routing them across split ground-plane boundaries.
Separate the controller’s supply requirements from downstream-port power delivery. The CY7C65620-56LTXCT manages USB hub traffic, but port loads still require correctly sized rails, switching, protection, and discharge paths. Confirm the exact operating voltage, current, decoupling, and power-sequence limits in the Infineon datasheet before defining the system power architecture.
Follow the manufacturer’s 56-QFN land pattern exactly and verify pin 1 orientation against the package drawing. Place required decoupling capacitors close to their associated terminals and use the recommended ground-via arrangement. If the selected package drawing identifies an exposed pad, implement its thermal and electrical requirements consistently rather than treating it as an undocumented extra terminal.
Do not treat suffix changes as purely cosmetic procurement details. The CY7C65620-56LTXCT is identified as tape and reel, while tray-oriented variants are distinguished by their ordering codes. Before substitution, confirm the 56-QFN footprint, pin functions, controller grade, and assembly format. A footprint match alone does not confirm that the incoming part matches the required production packing process.
