CY7C65630-56LTXCT - 4-Port USB 2.0 Hub Controller | Infineon
N.º da peça: CY7C65630-56LTXCT ✓ AtivoCY7C65630-56LTXCT Visão geral
A USB hub controller is an interface IC that manages one upstream USB connection and multiple downstream ports while handling enumeration, power-gating, overcurrent response, and transaction routing. The CY7C65630 belongs to the USB interface controller hierarchy, where USB 2.0 describes the bus speed and protocol generation. Its four-port single-TT architecture is intended for compact USB hubs, docking stations, monitor hubs, and embedded systems that need reliable downstream port expansion without a discrete host controller for each port.
Key device features include four downstream USB ports, integrated termination resistors, configurable general-purpose I/O pins, port-status indicator control, and EEPROM support for configuration storage. The integrated PLL accepts a 24 MHz reference crystal, while the in-system EEPROM programming function allows device configuration to be updated without a separate programming fixture. These features reduce the external component count and simplify firmware-based hub configuration.
The device is intended for 3.3 V operation. The manufacturer specifies a 3.15 V minimum and 3.45 V maximum operating supply, with a listed operating supply current of 231 mA. Because hub controllers coordinate multiple USB data paths, the design must preserve controlled-impedance routing between the upstream port, downstream ports, and external 24 MHz crystal network.
Typical uses include four-port USB 2.0 hubs, USB docking stations, shared-access peripherals, industrial USB expansion boards, and compact consumer accessories. The 56-pin QFN footprint also suits designs where connector placement and routing space are constrained. Tape-and-reel packaging supports automated assembly, and the C-grade ordering designation identifies the manufacturer's commercial temperature grade for this configuration.
When laying out the board, place the crystal and its load components close to the oscillator pins, provide continuous ground and power planes, and route each USB differential pair as a controlled-impedance pair without test pads or stubs. Decoupling capacitors should connect directly to the relevant supply and ground pins using short traces and via stitching. Verify downstream overcurrent handling, port enable sequencing, and USB enumeration behavior across the intended attachment sequence.

Aplicações típicas
CY7C65630-56LTXCT é adequado para 6 aplicaçãos: Compact Four-Port USB 2.0 Hub, USB Docking Station Hub, Industrial USB Expansion Board, Shared USB Peripheral Access Panel, USB-to-Serial Bridge Aggregator, Test and Measurement Hub Interface.
Compact Four-Port USB 2.0 Hub
The CY7C65630-56LTXCT fits a compact four-port USB 2.0 hub because it combines four downstream ports with a single-TT topology in one 56-pin QFN controller. Its integrated upstream and downstream termination resistors reduce discrete component count, while configurable GPIOs can support port-status LEDs and custom control functions. The 3.15 V to 3.45 V operating range aligns with standard 3.3 V hub designs. Place the 24 MHz crystal and load network close to the oscillator pins, and route every USB differential pair with continuous reference planes. The controller is also suitable for monitor hubs and desktop accessories where four full-speed or high-speed device connections must be managed by one upstream USB link.
Recomendado
USB Docking Station Hub
A USB docking station can use the CY7C65630-56LTXCT to consolidate peripheral connections behind one upstream port. Four downstream ports support keyboards, mice, storage devices, and card readers while the hub controller handles port attachment and status functions. Configurable GPIOs provide a flexible interface for LED indicators, power-enable control, or dock-state signaling. The single-TT configuration is appropriate for cost-conscious commercial docks, and the 8 x 8 mm QFN footprint leaves board area for connectors and power regulation. Because a dock commonly combines switched and unswitched power rails, the port-enable behavior and overcurrent response should be validated with the final connector and power-supply design.
Recomendado
Industrial USB Expansion Board
The CY7C65630-56LTXCT can serve as the USB interface for an industrial expansion board that exposes one host connection to four external peripherals. Its single-TT arrangement simplifies hub routing, and the integrated termination resistors help maintain repeatable signal behavior across downstream ports. The 24 MHz crystal interface with integrated PLL provides a standard clocking approach for a compact controller layout. For industrial equipment, confirm the selected ordering grade against the enclosure's internal temperature range and implement robust overcurrent handling. The controller also supports in-system EEPROM programming, which can simplify deployment of port-configuration data or product-specific hub settings.
Recomendado
Shared USB Peripheral Access Panel
A shared-access panel can use the CY7C65630-56LTXCT to provide four USB connections from a single upstream host interface. Port-status control allows the design to drive visible connection indicators, while configurable GPIOs can support enable controls or interface logic beyond the standard USB functions. Integrated upstream and downstream termination resistors are particularly useful when connector placement leaves limited board area. Designers should test enumeration behavior when several devices are attached simultaneously and verify that current limits on the downstream ports match the power architecture. This application is common in test benches, service panels, kiosk accessories, and shared workstations where cable access must be consolidated.
Recomendado
USB-to-Serial Bridge Aggregator
The four downstream ports of the CY7C65630-56LTXCT can organize multiple USB-to-serial adapters behind one host connection in test, maintenance, or legacy-equipment designs. Each downstream branch then connects to a dedicated interface bridge, while the hub controller manages attachment and port status. The controller's GPIO resources can assist with mode indicators or adapter-enable signals. Because serial bridges and USB hub lines have different rise times and edge requirements, keep the USB differential routes away from switching nodes and provide local decoupling. The 24 MHz crystal and integrated PLL offer a compact clocking arrangement, and EEPROM programming can store system-specific configuration where the host firmware supports it.
Recomendado
Test and Measurement Hub Interface
The CY7C65630-56LTXCT is useful in a test fixture that connects several USB instruments, service tools, or programmable devices to one host controller. Four downstream ports reduce the need for multiple root-hub resources and simplify port-level status indication. The configurable GPIOs can assist with fixture control signals, while the single-TT architecture simplifies the hub signal topology. In instrumentation, preserve clean separation between USB routing and sensitive analog or high-impedance measurement circuits. Keep the crystal loop compact, avoid stubs on USB pairs, and validate enumeration after power cycling when downstream devices have differing startup currents. The hub's 231 mA listed operating supply current must also be included in the fixture power-budget calculation.

Notas de projeto
Route the 24 MHz crystal circuit as a compact, symmetric network with the crystal and load components placed close to the CY7C65630-56LTXCT oscillator pins. Keep the traces short, avoid routing USB differential pairs beneath the crystal area, and provide a quiet ground reference. Because the controller contains an integrated PLL, clock-loop stability and ground-return continuity directly affect downstream hub behavior.
Implement each USB connection as a controlled-impedance differential pair with a continuous reference plane and no stubs, vias, or test pads that interrupt the pair. Keep the upstream and downstream routes away from switching regulators and high-current output stages. The integrated termination resistors reduce discrete parts, but they do not replace careful return-path and impedance management on the printed circuit board.
Estimated: the listed operating supply current is 231 mA at 3.3 V, giving a controller supply power of about 0.76 W using the inputs of 3.3 V and 231 mA. This excludes external USB-powered load current and auxiliary circuitry. The regulator must support the hub-controller demand plus downstream port budgets defined by the product architecture, and local decoupling should be placed directly beside the device's supply pins.
Do not treat every ordering suffix as electrically and commercially identical. The target code identifies the C-grade tape-and-reel configuration, while other HX2LP codes can change grade, temperature capability, device configuration, or delivery format. Before substitution, verify the pinout, USB port count, clock requirement, GPIO mapping, operating temperature, and assembly packaging against the manufacturer ordering guide.
