CY7C65630-56LTXIT 4-Port USB 2.0 Hub Controller | Infineon
料号： CY7C65630-56LTXIT ✓ 量产中CY7C65630-56LTXIT 概述
A USB hub controller is an interface integrated circuit that coordinates traffic between one upstream USB host and multiple downstream peripherals. It belongs to the USB interface controller family, a branch of interface ICs within the broader semiconductor hierarchy. Single-TT operation means that the controller uses one transaction translator to support its downstream USB functions, making it suitable for managed USB 2.0 hubs where device traffic must be segmented between a host connection and attached peripherals.
The CY7C65630 provides four downstream USB ports, configurable GPIO resources, LED-indicator support, and EEPROM support for hub metadata. These features allow a designer to implement port-status reporting and configurable hub behavior without relying on a separate controller for every peripheral. The 3.15 V minimum operating voltage provides margin for a regulated 3.3 V system rail, while the industrial temperature grade supports equipment intended for extended environmental duty.
The device uses a 56-pin QFN package with an exposed pad and a 0.5 mm lead pitch. Its compact 8 mm by 8 mm footprint is designed for high-density USB hub implementations, but the exposed pad requires deliberate thermal-plane construction and careful control of return-current paths. USB differential pairs should be routed as controlled-impedance interconnects, with the upstream and downstream connections following the layout guidance in the manufacturer datasheet.
Typical uses include four-port USB 2.0 docking stations, desktop monitor hubs, external storage enclosures, industrial interface panels, and embedded USB expansion systems. GPIO-driven status LEDs can indicate port activity, connection, or fault conditions, while EEPROM support can retain configuration information when the system design requires nonvolatile hub data.
The primary design trade-off is functional integration versus board complexity. The controller consolidates hub traffic management, port indication, GPIO, and EEPROM support into one device, but the 56-QFN footprint demands careful fanout, decoupling, and USB trace routing. Confirm the complete pin assignments, exposed-pad connection, crystal or clock requirements, and power sequencing directly from the manufacturer pin-description table before release.
This page organizes the controller’s principal specifications, application guidance, validated ordering alternatives, and PCB considerations into one engineering-focused reference. It also distinguishes confirmed drop-in replacements from ordering and temperature-grade variants so that board compatibility is not inferred from a superficial similarity.

典型应用
CY7C65630-56LTXIT 适用于 6 应用s: Four-Port USB 2.0 Docking Station, Desktop Monitor USB Hub, External Storage Enclosure, Industrial USB Interface Panel, USB-to-Serial Device Bridge, Embedded Test and Measurement Hub.
Four-Port USB 2.0 Docking Station
The CY7C65630-56LTXIT fits a docking station that presents one upstream USB 2.0 connection and four downstream peripheral ports. Its four-port single-TT architecture consolidates hub traffic management in one controller, while configurable GPIOs can drive connection or fault LEDs and EEPROM support can retain system configuration. The 3.15 V to 3.45 V operating range aligns with a regulated 3.3 V rail. In a dense dock, its 8 mm by 8 mm 56-QFN package saves board area but requires careful USB differential-pair routing, short supply connections, and an exposed-pad thermal design.
推荐
Desktop Monitor USB Hub
The CY7C65630-56LTXIT is suitable for a monitor or desktop accessory that adds USB connectivity without using a discrete hub controller for each port. Four downstream ports can support keyboards, mice, storage devices, and other USB 2.0 peripherals, while GPIO-controlled LEDs can expose port status. The single-TT topology helps organize traffic through the upstream link. Its industrial-grade ordering option and 3.15 V to 3.45 V core range suit controlled indoor equipment, although the 56-QFN exposed pad and 0.5 mm pitch demand careful assembly planning.
推荐
External Storage Enclosure
The CY7C65630-56LTXIT can manage USB connectivity in an enclosure that combines storage with peripheral ports. The four downstream ports allow a host to access a storage controller and additional devices through one upstream USB connection, while configurable GPIOs may drive activity indicators or control peripheral enables. EEPROM support can assist with configuration retention. The controller’s compact 56-QFN footprint helps when enclosure internals are constrained, but designers must maintain short USB traces, provide correct decoupling, and avoid routing high-current switching nodes beneath the exposed thermal area.
推荐
Industrial USB Interface Panel
The CY7C65630-56LTXIT is appropriate for an industrial interface panel that needs multiple USB 2.0 service connections and hardware status indication. The manufacturer identifies the target ordering option as industrial grade, while its configurable GPIO resources can support panel LEDs, enables, or fault inputs and EEPROM support can retain local configuration. The 3.15 V to 3.45 V operating range requires a stable 3.3 V rail. Because this is a high-density QFN device, production quality depends on thermal-pad soldering, inspection, controlled impedance routing, and adequate copper around the package.
推荐
USB-to-Serial Device Bridge
The CY7C65630-56LTXIT can serve as the hub-management element in a multi-interface bridge that connects USB peripherals to embedded controller logic. Four downstream ports provide expansion, and GPIO functions can assist with connection detection or peripheral enables. The single-TT hub structure consolidates traffic handling while EEPROM support can provide nonvolatile configuration storage. Integration into a compact embedded assembly requires exact pin assignment from the manufacturer data sheet, uninterrupted USB routing, and a power architecture that separates USB port-current demands from the controller's 3.15 V to 3.45 V core rail.
推荐
Embedded Test and Measurement Hub
The CY7C65630-56LTXIT fits an embedded test system that needs several USB 2.0 instruments or peripheral modules behind one host connection. Four downstream ports simplify enumeration, while configurable GPIOs can trigger indicator LEDs or assist equipment-status control, and EEPROM support can retain interface configuration. The single-TT architecture and 56-QFN footprint support compact multi-function instruments. Signal integrity remains the main constraint: each upstream and downstream differential pair should follow the manufacturer's reference layout, with minimized stubs and a continuous return path to preserve USB signal quality.

设计说明
Use the manufacturer pin-description table and recommended layout to assign every 56-QFN connection, especially the exposed pad. Route each USB 2.0 differential pair as a continuous impedance-controlled path without stubs, vias, or test pads where avoidable. Keep the pair length and surrounding return path consistent, and separate high-current switching nodes from the USB traces and controller ground references.
Power the controller from a regulated 3.3 V rail that remains between 3.15 V and 3.45 V under transient loading. Place the required bypass capacitors directly beside their associated supply and ground pins, then connect the exposed pad to the ground plane using the recommended via pattern. USB downstream port-current demand must be handled separately from the controller core rail so port switching does not disturb local decoupling.
Treat the exposed pad as both a thermal and electrical connection. Provide uninterrupted ground copper beneath the package, use the datasheet-recommended thermal-via pattern, and avoid placing heat-generating regulators or power-conversion stages immediately beneath the QFN. Validate the assembled board at the maximum intended ambient temperature and load rather than relying only on a thermal estimate from the package dimensions.
Do not substitute CY7C65630 ordering codes without checking every suffix. The manufacturer identifies CY7C65630-56LTXIT as the tape-and-reel, industrial-grade option, while CY7C65630-56LTXC is identified as a bulk, commercial-grade option. Likewise, temperature-grade variants such as CY7C65630-56LTXA require separate qualification. Confirm the pinout, grade, package form, and lead-finish requirements before substitution.
