CY7C65634-28LTXC 概述
A USB hub controller is an interface-controller semiconductor that manages traffic between one upstream USB host connection and multiple downstream ports. Within the hierarchy, this device is a USB interface controller, then a USB hub controller, then a USB 2.0 peripheral, and finally an integrated circuit. Its two-port Single-TT topology consolidates USB traffic-management functions while leaving port behavior configurable for compact external hubs, docking equipment, and embedded USB expansion.
The verified product information identifies USB 2.0 operation, two downstream ports, Low Speed, Full Speed, and High Speed support, GPIO and EEPROM configurability, a 4.75 V to 5.25 V operating range, and a 28-QFN 5 mm by 5 mm package. Infineon describes the device as the EZ-USBTM HX2VL very-low-power USB 2.0 hub controller. The bulk shipping form and C-grade suffix distinguish it from the separately identified CY7C65634-28LTXCT tape-and-reel ordering option.
Technically, the Single-TT architecture is significant because each downstream port receives dedicated transaction-traffic handling rather than relying on a shared legacy topology. That architecture helps the controller organize USB traffic while supporting devices operating across the USB 2.0 speed set. GPIO and EEPROM configuration also allow a product designer to adapt port behavior without treating the controller as a fixed-function hub.
Typical uses include compact USB hubs, USB docking stations, embedded computing systems, test equipment, and peripheral-expansion products. The controller fits designs that need one upstream USB connection and two downstream ports while preserving support for both low- and high-speed USB devices.
The primary design considerations are pin assignment, exposed-pad thermal management, USB routing, power distribution, and connector protection. Designers should use the manufacturer datasheet for the complete pin map, electrical limits, reference schematics, layout guidance, and configuration procedure rather than inferring these details from the distributor summary.
This page combines the verified manufacturer description, distributor availability information, and explicitly identified ordering alternatives. It also separates confirmed product facts from parameters that require direct confirmation from the manufacturer datasheet, avoiding unsupported electrical or layout assumptions.

典型应用
CY7C65634-28LTXC 适用于 7 应用s: Compact Two-Port USB 2.0 Hub, USB Docking Station, Industrial USB Peripheral Expansion, Embedded Computing USB Hub, USB Test and Measurement Fixture, USB-to-Serial Bridge Hub, USB Audio Accessory Hub.
Compact Two-Port USB 2.0 Hub
The CY7C65634-28LTXC is a direct fit when an enclosure needs one upstream USB connection and two downstream USB 2.0 ports. Its Single-TT topology manages both downstream ports while the verified support for Low Speed, Full Speed, and High Speed devices keeps the design from being limited to one USB speed class. GPIO and EEPROM configurability can also adapt operating behavior to a particular product implementation. The 4.75 V to 5.25 V operating range fits the documented hub-supply environment. Final port-current limits, protection components, and trace geometry are not present in the supplied data and must be taken from the manufacturer documentation rather than estimated.
推荐
USB Docking Station
A docking station can use the CY7C65634-28LTXC to add two USB 2.0 downstream connections without placing a separate host controller beside the host computer. The two-port Single-TT arrangement provides a defined hub architecture, while Low Speed, Full Speed, and High Speed support allows peripherals with different transfer capabilities to share the hub. GPIO configuration may support product-specific behavior and EEPROM allows firmware or hub descriptors to be associated with the implementation. The 28-QFN 5 mm by 5 mm package saves board area, although exposed-pad layout and USB signal integrity remain design-critical. Connector protection and power limits should be verified from the datasheet before implementation.
推荐
Industrial USB Peripheral Expansion
The CY7C65634-28LTXC is suitable for compact industrial equipment that needs to expand one host USB connection into two controlled downstream ports. Its verified 0 °C to 70 °C operating range is appropriate for commercial-temperature equipment, and the controller can use GPIO or EEPROM configuration to support product-specific port behavior. The Single-TT topology is useful when deterministic traffic handling across both downstream ports matters. Because the verified data does not include industrial certification, surge ratings, or isolated USB requirements, this component should not be treated as sufficient for harsh environments without additional protection and validation. Keep sensitive routing compact and follow all manufacturer implementation guidance.
推荐
Embedded Computing USB Hub
An embedded computer or controller platform can use the CY7C65634-28LTXC when its processor exposes only one practical USB host port but the system requires two external USB connections. The device's two-port Single-TT topology provides the hub function in a single 28-QFN package, while support for all three verified USB 2.0 speed classes improves peripheral flexibility. GPIO and EEPROM configurability can accommodate board-level identification or implementation-specific hub behavior. The 5 mm by 5 mm footprint supports compact designs, provided the exposed pad receives the required copper and assembly process. Exact routing, decoupling, and port-power limits remain unspecified in the supplied evidence and require manufacturer documentation.
推荐
USB Test and Measurement Fixture
A USB test fixture can use the CY7C65634-28LTXC to present two downstream USB 2.0 ports to a host-controlled instrument or peripheral. Keeping Low Speed, Full Speed, and High Speed support in one controller can simplify test coverage across different device classes, and GPIO configuration can provide fixture-specific behavior. The Single-TT design organizes downstream traffic while preserving a compact 5 mm by 5 mm footprint. In a laboratory fixture, the ports still need appropriate data protection and correctly terminated power distribution. The supplied data contains no electrical-output, current-limit, rise-time, or signal-integrity figures, so test engineers should use the official datasheet and reference layouts rather than extrapolate from distributor summaries.
推荐
USB-to-Serial Bridge Hub
A service-oriented USB hub can pair the CY7C65634-28LTXC with one or more USB-to-serial interface devices while presenting two downstream ports to the host. The controller's two-port Single-TT topology provides shared USB expansion, and GPIO or EEPROM configurability can support identification or product-specific setup. The 4.75 V to 5.25 V supply range aligns with the documented operating environment, while the 28-QFN package limits board occupancy. The target itself does not perform protocol conversion, so the downstream interface devices still require correct drivers and device descriptors. Verify downstream power budgets, inrush behavior, and connector protection from the complete manufacturer documentation before combining multiple adapters on one hub.
推荐
USB Audio Accessory Hub
A compact audio accessory can use the CY7C65634-28LTXC to provide two USB-facing ports while the system handles audio signal processing locally. The verified USB speed support allows connected devices to operate at Low Speed, Full Speed, or High Speed according to their capabilities, and the Single-TT topology manages the two downstream links. GPIO and EEPROM configuration can support device-specific hub behavior. Because the supplied data does not specify audio-class integration, clocking, or bus-power limits, this controller should be treated as the USB routing component rather than as a complete audio solution. Add the required audio interface separately and follow the official USB routing and exposed-pad guidance.

设计说明
Use the manufacturer QFN land pattern and exposed-pad recommendations rather than a generic 28-QFN footprint inferred from the 5 mm x 5 mm body size. USB differential traces should remain continuous and symmetric, with connector and protection components placed according to the official reference layout. The supplied evidence confirms the package but does not provide trace widths, spacing, layer count, or pad dimensions, so those values cannot be responsibly invented here.
Design the 4.75 V to 5.25 V supply path to satisfy both hub-controller requirements and the total downstream USB load. Verify input capacitance, current limits, port-power rules, and sequencing from the manufacturer datasheet before assigning a regulator or protection scheme. Do not assume that the controller itself regulates all downstream power; the verified source identifies port capability and supply range but does not provide complete power-distribution limits.
Do not substitute CY7C65634-28LTXCT solely because search results call the devices equivalent. Confirm that the PCB uses the same pin assignment and exposed-pad connection, then check whether the assembler accepts bulk or requires tape and reel. The only supplied direct cross-reference is an Infineon ordering form of the same controller; other series may differ functionally even if their USB speed labels are similar.
Follow the official USB 2.0 High-Speed implementation guidance for routing D+ and D-, return paths, connector transitions, ESD protection, and branch geometry. The verified data confirms High Speed support but provides no edge-rate or impedance target, so board-level values must come from the manufacturer datasheet and reference design. Keep protection routing from disrupting the controlled impedance path and verify signal integrity across every intended cable and accessory combination.
合规信息
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status. AEC-Q100 is marked not_applicable only because this USB interface controller is positioned for commercial-temperature hub applications rather than an explicitly automotive-qualified device.
