TUSB5052PZ - 5-Port USB 2.0 Hub Controller with Serial Bridge | Texas Instruments
N.º de pieza: TUSB5052PZ ✓ ActivoTUSB5052PZ Descripción general
A USB hub controller is a semiconductor that manages traffic between one upstream USB connection and multiple downstream USB ports. The TUSB5052PZ belongs to the broader USB interface controller hierarchy, where USB interface ICs connect host controllers, peripherals, hubs, bridges, and external serial devices. Its configurable optional hub capability allows designers to combine hub and serial-interface functions in one device instead of allocating separate ICs for those functions.
The verified listing identifies the TUSB5052PZ as a five-port USB 2.0 hub controller with a bridge to two serial ports. Its maximum clock frequency is 6 MHz, while its stated data-transfer rate is 1.5 MBps. The nominal operating voltage is 3.3 V, matching the power level commonly used by USB 2.0 interface circuitry. These characteristics make the controller relevant to embedded USB systems requiring multiple USB connections alongside serial-port expansion.
The 100-LQFP (14 x 14 mm) package provides 100 external terminals and a square, gull-wing surface-mount form. Compared with a smaller connector-oriented USB interface package, this device exposes a substantially larger pin count to support hub-port and serial-bridge functions. Its specified commercial temperature grade is suitable for ordinary commercial equipment, although manufacturer ordering information and the full datasheet should be checked for detailed electrical limits and qualification requirements.
Typical application areas include industrial control panels, multifunction printers, point-of-sale terminals, external storage enclosures, test equipment, and legacy-port expansion systems. In each case, the controller can sit between a USB host and downstream peripherals while presenting serial connectivity to embedded subsystems. System-level performance remains dependent on upstream USB bandwidth, device scheduling, cable quality, enumeration behavior, and the electrical implementation of the connected ports.
Designers should verify every signal, supply, and termination connection against the manufacturer datasheet before layout release. The large 100-terminal package demands careful escape routing between fine-pitch leads, while USB differential pairs require controlled impedance and minimized stub length. Decoupling and high-speed return paths should also be planned so that the 3.3 V interface supply and USB data paths are not compromised by adjacent digital or switching circuitry.
This product record combines the verified distributor specifications, commercial availability references, package information, and cross-reference findings for the TUSB5052PZ. It also documents where additional engineering data remain necessary, including detailed pin assignments, electrical limits, lifecycle declarations, pricing, and validated drop-in replacements. Those gaps are intentionally marked rather than replaced with unverified datasheet or substitution claims.

Aplicaciones típicas
TUSB5052PZ es adecuado para 6 aplicacións: Industrial Control Panel USB Hub, Multifunction Printer Peripheral Expansion, Point-of-Sale Terminal USB Expansion, External Storage Enclosure USB Hub, Test and Measurement USB Interface, Embedded USB-to-Serial Expansion.
Industrial Control Panel USB Hub
The TUSB5052PZ fits an industrial panel that must expose several USB connections while retaining serial connectivity to a controller or service interface. Its verified five-port USB 2.0 hub function consolidates downstream USB expansion, while the bridge to two serial ports can connect compatible embedded subsystems. The 3.3 V nominal supply aligns with typical USB interface rails, and the 6 MHz maximum clock provides a documented basis for clock and topology review. The 100-LQFP package occupies substantially more PCB area than a small USB interface IC, so enclosure space, thermal conditions, and routing resources must be confirmed. Before production release, verify the complete pin assignment, USB electrical requirements, operating-temperature limits, and ESD implementation in the current manufacturer datasheet.
Recomendado
Multifunction Printer Peripheral Expansion
The TUSB5052PZ is suitable for multifunction-printer electronics that need to expose multiple USB device ports and maintain links to legacy or embedded serial subsystems. The verified five-port hub function provides a clear topology for keyboards, card readers, scanners, and service connections, while the integrated two-port serial bridge adds peripheral flexibility. Its documented 1.5 MBps data-transfer rate and 6 MHz maximum clock must be evaluated against the printer data path and USB host scheduling requirements. The commercial grade suits ordinary commercial equipment, but enclosure temperature and conducted-noise conditions still apply. Layout should preserve USB differential impedance, provide a continuous ground reference, and route sensitive serial and USB signals away from motors, power stages, and high-current return paths.
Recomendado
Point-of-Sale Terminal USB Expansion
The TUSB5052PZ can support a point-of-sale terminal that must connect several USB peripherals while communicating with internal serial equipment. Its five-port USB 2.0 hub capability is appropriate for payment accessories, scanners, printers, or storage devices, and the two-port serial bridge can preserve connectivity to internal subsystems. The 3.3 V nominal operating voltage simplifies alignment with many USB peripheral interfaces, although every supply tolerance must be checked from the manufacturer datasheet. A 100-terminal LQFP requires deliberate fanout routing on a multilayer PCB. USB differential pairs should have matched geometry and uninterrupted reference planes, while exposed serial lines require appropriate protection and isolation from display, keypad, and power-converter switching nodes.
Recomendado
External Storage Enclosure USB Hub
The TUSB5052PZ can serve as the hub-control element in an external storage enclosure that presents several USB connections to a host computer. The verified USB 2.0 hub function supports the aggregation of peripherals, and the two serial ports may provide an additional management path to an embedded storage controller or configuration interface. The published 1.5 MBps transfer-rate figure and 6 MHz maximum clock should be checked against the intended storage workload and enumeration architecture. Thermal design must keep the large LQFP within the commercial-grade operating limits confirmed by the manufacturer. The enclosure should minimize ESD and EMI paths by keeping host and peripheral connectors away from noisy switching circuitry, using controlled-impedance USB routing, and providing local high-frequency decoupling at the controller.
Recomendado
Test and Measurement USB Interface
The TUSB5052PZ is applicable to test and measurement equipment that needs several USB peripheral connections plus serial access to an internal instrument controller. The five-port USB 2.0 hub function can organize front-panel peripherals, maintenance interfaces, and data-transfer devices, while the integrated serial bridge provides a path to compatible embedded or legacy control logic. The verified 6 MHz maximum clock and 1.5 MBps rate are concrete values against which architecture and signal-integrity constraints can be checked. Because this is a 100-terminal LQFP, board designers should budget for fine-pitch escape routing and a multilayer stack-up. Measurement-sensitive circuits also require careful grounding, shielding, and separation from the USB and serial connector return currents to prevent coupling into the instrument signal chain.
Recomendado
Embedded USB-to-Serial Expansion
The TUSB5052PZ is well matched to embedded systems that need to bridge USB connectivity to two serial interfaces while also supporting an optional multiport hub configuration. The integrated combination can simplify the architecture of an embedded controller, service appliance, or industrial gateway that previously required separate hub and serial bridge devices. Its 3.3 V nominal supply is suitable for integration with USB 2.0 interface logic, but the absolute voltage limits and power-consumption values must be verified from the manufacturer datasheet. Designers should confirm that the intended serial electrical standard is supported by the exact TUSB5052PZ configuration. PCB implementation should use short USB routes, solid plane returns, deliberate escape routing for all 100 leads, and protection appropriate to the externally accessible connector environment.

Notas de diseño
Plan the 100-LQFP footprint with fanout that can be manufactured without excessive vias beneath the device. Use the manufacturer land pattern and recommended PCB stack-up rather than constructing the 14 mm by 14 mm footprint from package dimensions alone. Confirm pad, solder-mask, and copper-clarance geometry against current assembly documentation. The fine-pitch gull-wing terminals also make thermal-via placement near the exposed area important where the package includes a thermal pad.
Route USB differential pairs as impedance-controlled, tightly coupled nets over a continuous reference plane, and minimize via count, stubs, and branch lengths. Keep connector entry paths away from switching-regulator switches and high-current power loops. The verified 6 MHz maximum clock and 1.5 MBps transfer rate do not replace compliance testing, so USB eye, impedance, ESD, and enumeration behavior should be validated on the assembled board.
Separate the USB interface and serial bridge routing from noisy analog, relay, motor, and display-power sections. Provide a direct return path beneath each high-speed pair and place local bypass capacitance at the controller supply pins according to the manufacturer application guidance. External connectors should include the protection network specified by the datasheet because externally accessible USB and serial lines can be subjected to ESD and surge events not represented by ordinary bench conditions.
