TUSB2136PM - 2-Port USB 2.0 Hub Controller | Texas Instruments
料号： TUSB2136PM ✓ 量产中TUSB2136PM 概述
A USB hub controller is an interface integrated circuit that manages a USB host connection and coordinates attached USB devices. Within the product hierarchy, a USB 2.0 hub controller is an interface IC, a USB interface device, and a semiconductor. This TUSB2136 variant combines two-port hub control with a general-purpose function controller, allowing the hub function and device-side control logic to be consolidated within one package.
The principal verified features are two USB 2.0 ports, a 3 V to 3.6 V operating-supply range, and integrated general-purpose function control. The controller is packaged in a 64-pin LQFP measuring 10 mm by 10 mm, providing a surface-mount implementation for compact USB equipment. The operating temperature range of 0 °C to 70 °C identifies it as a commercial-temperature option rather than an explicitly automotive-qualified or extended-temperature device.
The TUSB2136PM combines a compound USB hub function with an embedded general-purpose 8052 MCU, as identified in the supplied datasheet result. This architecture is useful when downstream equipment needs local device handling, configuration logic, or peripheral control in addition to standard USB hub behavior. Its consolidated approach can reduce the number of discrete interface components required around a USB connection, although the complete implementation must be validated against the manufacturer datasheet and reference design.
Typical uses include USB connection hubs, computer peripherals, docking equipment, and embedded USB interface products. Its two-port configuration is appropriate for systems that need to expose multiple USB connections through one upstream USB link. Integration of the general-purpose function controller is especially relevant to designs in which hub management must coexist with vendor-specific control behavior or device-specific handling.
Designers should pay particular attention to USB signal routing, supply decoupling, and the exact pin assignments shown in the manufacturer documentation. Because the verified sources do not provide the complete pin table, crystal requirements, programming interface, USB transceiver details, or decoupling values, those items must be obtained from the official datasheet before schematic capture. No automotive qualification or regulatory status beyond the supplied active-status information should be inferred.
This page combines the verified USB version, port count, supply range, package, temperature range, lifecycle status, and distributor availability information with practical integration guidance. It also distinguishes documented characteristics from unknown electrical details and avoids presenting unverified pinout or replacement claims as drop-in-compatible alternatives.

典型应用
TUSB2136PM 适用于 6 应用s: Two-Port USB Hub, USB Docking Station, USB Computer Peripherals, Industrial USB Interface Equipment, USB Test and Measurement Front End, Embedded USB Connectivity Module.
Two-Port USB Hub
The TUSB2136PM fits a two-port USB 2.0 hub because the verified part description identifies two hub ports and USB 2.0 operation. Place the controller between the upstream USB connection and the two downstream ports, then implement the connector, protection, routing, and device-power network around it. The integrated general-purpose function controller can also handle product-specific hub behavior, reducing the need for a separate MCU when the design genuinely needs local control. The key trade-off is that firmware and clock validation become part of the hub design effort rather than being limited to a basic hub-only configuration.
推荐
USB Docking Station
The TUSB2136PM can serve as the USB interface core in a docking station that exposes two USB 2.0 connections while retaining product-specific control logic. Its verified 3 V to 3.6 V operating range is compatible with a 3.3 V-based interface design, and the integrated general-purpose function controller can coordinate peripheral state or configuration beyond basic hub enumeration. Designers must allocate board area for the 64-LQFP (10×10) package and carefully route the USB data pairs. Firmware requirements, enumerator behavior, and downstream power management must be validated with the manufacturer documentation.
推荐
USB Computer Peripherals
The TUSB2136PM is suitable for a USB peripheral that needs to expose two USB connections and also perform local control. The active lifecycle status, USB 2.0 interface, and integrated general-purpose 8052 MCU allow hub and device-management functions to share one controller package. This can simplify the architecture compared with separating hub control from product-specific firmware, provided the system has a suitable firmware-development and validation plan. The 0 °C to 70 °C specified range supports commercial environments, while the 64-LQFP footprint requires disciplined high-speed USB layout and careful decoupling.
推荐
Industrial USB Interface Equipment
The TUSB2136PM can form part of an industrial USB interface device where two USB 2.0 ports and an embedded controller provide a practical combination of connectivity and local logic. Its verified 0 °C to 70 °C range covers many indoor commercial and industrial enclosure environments, provided the internal temperature remains within specification. The 3 V to 3.6 V supply range supports 3.3 V system rails, and the integrated general-purpose function controller may simplify device configuration. Industrial suitability must nevertheless be assessed case by case because extended-temperature, EMC, and functional-safety requirements are not documented in the supplied data.
推荐
USB Test and Measurement Front End
The TUSB2136PM can provide the hub interface and embedded control function for a USB-connected test front end that needs two downstream USB ports. The general-purpose controller can support device identification, configuration sequencing, or front-panel control alongside the hub role. The verified 3 V to 3.6 V range and 0 °C to 70 °C specification are appropriate for many benchtop products, but low-noise analog sections should not share uncontrolled supply paths with USB activity. Preserve the USB data-pair geometry, isolate sensitive rails where necessary, and verify the complete system behavior against the manufacturer application information.
推荐
Embedded USB Connectivity Module
The TUSB2136PM fits an embedded connectivity module that presents a two-port USB 2.0 hub to an external host while using its integrated general-purpose controller for local configuration. Consolidating these functions can simplify the module firmware and reduce the number of USB-related integrated circuits on the board. The verified surface-mount 64-LQFP (10×10) package is manageable in a compact module, provided the PCB supports its footprint and thermal requirements. Confirm the complete pinout, clock arrangement, programming workflow, and enumeration behavior from the official datasheet before finalizing the module architecture.

关键差异点
- Hub control and general-purpose control are consolidated （对比 A conventional two-port USB hub controller without an integrated general-purpose 8052 MCU)
- Two-port integration in a defined surface-mount footprint （对比 A discrete USB hub and separate peripheral-controller implementation)
- Explicit 3.3 V-class operating range （对比 A USB interface device requiring a different documented operating-supply range)
设计说明
Treat USB D+ and D− as a controlled-impedance differential pair from the controller to the connector. Keep the pair geometry consistent, minimize stubs and vias, and place ESD protection close to the external connector. The verified sources identify the USB 2.0 interface and package but do not provide trace-length, impedance, or placement values, so obtain the manufacturer's reference layout and layer stack guidance before fabrication.
Design the 3.3 V supply path around the documented 3 V to 3.6 V operating range. Verify startup, current consumption, downstream-load behavior, and the required bypass network using the official datasheet; those values are not present in the supplied search snippets. Place local decoupling at the device supply pins and use the manufacturer's reference schematic rather than estimating capacitor values from generic USB guidance.
Do not substitute a component merely because it is labeled a USB 2.0 hub controller. A valid redesign alternative must match the 64-LQFP (10×10) footprint, pin assignments, supply requirements, clocking, firmware model, and downstream-port behavior. No verified drop-in replacement was identified for TUSB2136PM, so changing the MPN without a manufacturer-supported migration path can cause enumeration failures or PCB rework.
Do not infer the complete pinout from generic USB hub-controller conventions. The verified data establishes a 64-LQFP package and an integrated general-purpose 8052 MCU, but it does not provide numbered signal names, programming pins, clock requirements, or test conditions. Download the official Texas Instruments datasheet and cross-check its symbol, pin table, package drawing, and application circuit before schematic capture or PCB release.
合规信息
The supplied sources confirm an active lifecycle status but do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Compliance must be checked on the current Texas Instruments product page and applicable material declarations.
