USB2412-DZK-TR - 2-Port USB 2.0 Hub Controller | Microchip (Tape & Reel)
MPN： USB2412-DZK-TR ✓ 啟用中USB2412-DZK-TR 概覽
A USB hub controller is an interface IC that manages traffic between one upstream USB host connection and multiple downstream USB ports. The USB2412 belongs to the USB interface-controller hierarchy, where USB 2.0 connectivity, transaction translation, port management, and embedded system integration combine into a dedicated hub solution. Its single Transaction Translator, or STT, architecture is intended to reduce implementation complexity in compact USB hub designs.
The verified product information identifies two downstream ports, USB 2.0 operation, low-power operation, and support for low-speed, full-speed, and high-speed downstream devices when the hub operates at high speed. The controller is available in a 28-QFN package, while distributor records identify the package as 28-VFQFN with an exposed pad. The USB interface supports system integration with embedded USB host, peripheral, docking, and industrial equipment designs.
The 3 V to 3.6 V operating supply range places the device in a low-voltage digital interface class. USB data integrity depends on correct PCB routing, adequate power distribution, compliant connector implementation, and proper decoupling. The exposed-pad package requires attention to thermal and layout practices, even though the verified snippets do not provide a complete electrical limit table or detailed power-consumption values.
Typical applications include two-port embedded USB hubs, self-powered USB equipment, industrial control systems, test and measurement fixtures, docking equipment, and compact host systems that need USB device expansion. The two-port architecture is useful when a system must connect peripherals without adding multiple independent host controllers.
When selecting a replacement, verify the complete pinout, package dimensions, exposed-pad connection, USB signal routing, clock requirements, and power sequencing against the original design. The USB2412-DZK-TR-TR is a tape-and-reel ordering variant, while other listed controllers or transceivers may provide different functions and must not be treated as drop-in substitutes without manufacturer verification.
This page consolidates the verified manufacturer description, distributor package data, official datasheet link, application guidance, and cross-reference findings to support engineering selection. It distinguishes confirmed USB2412 attributes from parameters that require the manufacturer datasheet or an authorized design review.

典型應用
USB2412-DZK-TR 適用於 6 應用s: Embedded Two-Port USB Hub, Industrial Control USB Expansion, Self-Powered USB Peripheral Hub, Test and Measurement USB Fixture, USB Docking and Service Equipment, Compact Embedded Host System.
Embedded Two-Port USB Hub
The USB2412-DZK-TR fits embedded equipment that needs one USB host connection to serve two downstream peripherals. Its confirmed two-port USB 2.0 hub architecture reduces the need for separate hub controllers, while STT operation supports low-speed, full-speed, and high-speed devices when the hub operates at high speed. The 3 V to 3.6 V supply range and 28-QFN package suit compact embedded designs. Designers should allocate connector power, protection, and routing resources around the controller and confirm firmware support for enumeration and device-specific power requirements.
推薦
Industrial Control USB Expansion
USB2412-DZK-TR can add peripheral connectivity to industrial control equipment without requiring a separate host interface for each port. The confirmed support for low-speed and full-speed devices is useful for control peripherals, while high-speed support is available when the hub operates as a high-speed hub. In an industrial enclosure, the design should include surge and ESD protection, defined connector current limits, isolation requirements where applicable, and careful separation between USB routing and noisy power or motor circuits. The controller’s 3 V to 3.6 V supply range supports integration into embedded 3.3 V systems.
推薦
Self-Powered USB Peripheral Hub
The USB2412-DZK-TR is suitable for self-powered equipment that exposes two USB ports to external devices. Its two downstream ports allow the host system to manage peripherals such as keyboards, storage, communications adapters, or service interfaces. Because the verified data does not specify USB power-current limits or operating current, the power supply must be sized from the system’s actual device-load requirements and the applicable USB standard. The controller should be paired with protection and filtering appropriate to exposed connectors, while preserving controlled-impedance differential routing from the QFN pins to the connectors.
推薦
Test and Measurement USB Fixture
USB2412-DZK-TR can be used in test and measurement fixtures that need to bring two external USB devices onto one embedded host interface. The controller’s two downstream ports provide a straightforward expansion path for instrumentation, configuration adapters, and service peripherals. The USB 2.0 specification and low-, full-, and high-speed support make the device broadly adaptable, but the host software must handle enumeration, driver loading, and bus-power limits. Layout should minimize USB trace length and discontinuities, while grounding and shielding should follow the enclosure and connector implementation.
推薦
USB Docking and Service Equipment
USB2412-DZK-TR is applicable to docking and service equipment that consolidates two external USB connections around an embedded controller. Its two-port architecture can simplify mechanical and firmware planning compared with two unrelated host interfaces, while the 28-QFN package supports compact board construction. Dock designs should account for connector insertion forces, ESD exposure, cable faults, device-disconnect events, and power-cycle behavior. Firmware must also support the intended operating-system USB stack and validate any device classes that may be connected through either downstream port.
推薦
Compact Embedded Host System
USB2412-DZK-TR can expand USB connectivity in compact embedded host systems that require peripherals beyond the host processor’s direct port budget. The single Transaction Translator architecture and two downstream ports provide a focused USB 2.0 hub function without requiring a larger multi-port hub controller. The 3 V to 3.6 V operating range is compatible with common embedded digital rails, although the complete power and timing requirements must be checked in the official datasheet. Board-level validation should include hot-plug behavior, suspend and resume, device brownout behavior, and simultaneous-load testing.

主要差異化特點
- Confirmed two-port embedded USB hub architecture (對比USB82642AM-A-000528)
- Explicit STT hub implementation (對比USB2412-DZK-TR-TR)
- Verified low-power 3 V to 3.6 V operating range (對比USB82642AM-A-000528-V02)
- Confirmed support for low-, full-, and high-speed downstream devices (對比USB82642AM-A-000528-V05)
設計說明
Route the USB high-speed differential pairs as controlled-impedance traces with continuous reference planes and minimize stubs, vias, and unnecessary copper changes. Keep the USB data pairs away from switching nodes and high-current power paths. Place connector-side protection and filtering close to the connector, while maintaining the return-current path so that common-mode noise is not injected into the USB data pairs.
Confirm the complete electrical current, power-state, and USB bus-power requirements in the manufacturer datasheet before selecting the system supply and connector protection. The verified data confirms a 3 V to 3.6 V controller supply range but does not provide a full current table. Decoupling should follow the datasheet recommendations and be placed close to the supply pins, with additional bulk energy storage placed according to the load-transient profile.
Use the exposed pad according to the official 28-QFN land-pattern guidance. Provide thermal vias and a suitable copper area without compromising USB return paths or isolation clearances. Thermal performance depends on the PCB stackup, copper area, via arrangement, and enclosure airflow, so estimate junction temperature with the manufacturer’s package data rather than relying only on nominal package size.
Do not treat USB2412-DZK-TR, USB2412-DZK-TR-TR, or the base USB2412 listing as interchangeable solely because their names are similar. Verify the exact ordering code, package, pinout, firmware assumptions, and electrical characteristics. Likewise, do not assume that another USB controller is a drop-in replacement: the supplied data explicitly says USB2412-DZK-TR is not pin-to-pin compatible with TUSB2046B because the package and integration differ.
合規資訊
The supplied verified results identify the manufacturer, USB function, supply range, package, and official datasheet, but do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. Compliance fields therefore remain unknown rather than inferred.
