USB7056-I/KDX Übersicht
A USB hub controller (USB 3.0/3.2 Gen 1 hub) is a semiconductor device that expands a single upstream USB port into multiple downstream ports, while managing enumeration, power, and protocol translation. The USB hub sits within the broader USB connectivity IC hierarchy: USB hub controller -> USB interface IC -> connectivity semiconductor -> IC. SmartHub variants add on-board PD negotiation and Type-C cable-orientation logic, eliminating the need for an external PD controller in Type-C sink/source designs.
Key features include USB 3.2 Gen 1 (5 Gbps) SuperSpeed with native Type-C support, integrated USB PD 3.0 controller, broad host interfaces (GPIO, I2C, I2S, SPI, UART) for peripheral control, flexible GPIOs for status and indicators, integrated 5V LDO regulators for downstream VBUS, and support for battery charging (BC1.2) on each downstream port. The KDX suffix denotes the specific 100-VQFN lane mapping optimized for Type-C + 5x Type-A embedded designs.
Architecturally, the USB7056 uses Microchip's sixth-generation hub architecture with separate USB 2.0 and USB 3.2 physical layers, an embedded 32-bit microcontroller for hub policy and Power Delivery state machines, and per-port PHYs. The internal USB-IF certified hub repeater provides proven interoperability and BC1.2 CDP/SDP/DCP charging modes are configurable per port.
Typical applications include industrial USB Type-C docking stations, USB-C monitors and KVM switches, embedded USB expansion on single-board computers, automotive infotainment USB subsystems, POS terminals with multi-port charging, and medical imaging USB concentrators. Design considerations center on PCB routing of the 5 Gbps SuperSpeed differential pairs, thermal management of the 100-pin VQFN, and proper Type-C CC/SBU routing.
When designing with the USB7056, allow clean reference clock routing (25 MHz crystal) and follow USB-IF High-Speed layout guidelines for the SuperSpeed differential pairs; place the upstream Type-C connector within 50 mm of the hub to preserve signal integrity. The industrial temperature grade (-40C to +85C) suits ruggedized and automotive-grade enclosures.

Typische Anwendungen
USB7056-I/KDX ist geeignet für 6 Anwendungs: Industrial USB Type-C Docking Station, USB-C Monitors and KVM Switches, Point-of-Sale (POS) Terminal USB Expansion, Medical Imaging USB Concentrator, Automotive Infotainment USB Subsystem, Embedded SBC USB Expansion Header.
Industrial USB Type-C Docking Station
The USB7056-I/KDX's integrated USB PD 3.0 controller and native Type-C upstream port make it ideal for industrial docking stations that must deliver 5V/3A or higher negotiated profiles to a notebook host while simultaneously serving five Type-A peripherals at full 5 Gbps SuperSpeed. The 100-VQFN industrial temp grade (-40C to +85C) tolerates factory floor heat without derating SuperSpeed eye performance, and the SmartHub configuration registers expose port power and billboard data via I2C for embedded system telemetry.
Empfohlen
USB-C Monitors and KVM Switches
A USB-C monitor with KVM switching benefits from the USB7056-I/KDX's 6-port topology by combining one Type-C upstream to the laptop with five Type-A ports wired to keyboard, mouse, webcam, headset, and storage. The integrated PD controller negotiates 5V/3A or higher power profiles to charge the host laptop while SuperSpeed passthrough preserves USB 3.2 Gen 1 throughput for an external SSD. Host-side GPIO interrupts notify the MCU on CC state changes for KVM port routing.
Empfohlen
Point-of-Sale (POS) Terminal USB Expansion
Retail POS terminals typically require 1 USB Type-C upstream connection to a tablet register plus 5 Type-A peripherals (barcode scanner, receipt printer, cash drawer, customer display, NFC reader). The USB7056-I/KDX's BC1.2 CDP/SDP/DCP per-port charging modes power each Type-A downstream port without external charge ICs, and its industrial temperature rating supports semi-outdoor retail kiosks. The SmartHub I2C bus reports port connect/disconnect events to the POS application for diagnostics.
Empfohlen
Medical Imaging USB Concentrator
In medical imaging, ultrasound carts and endoscopy processors use the USB7056-I/KDX to consolidate a 5MP camera, frame grabber, keyboard, mouse, and a tethered tablet through one Type-C upstream while SuperSpeed lanes maintain uncompressed video bandwidth. The industrial temperature variant tolerates ambient hospital equipment heat, and separately regulated per-port VBUS isolates sensitive imaging sensors from brownout events. The I2S interface streams audio prompts from the host to integrated speakers on the cart.
Empfohlen
Automotive Infotainment USB Subsystem
Automotive head units and rear-seat entertainment modules use the USB7056-I/KDX to expose 1 Type-C charging port for the driver's phone (with PD 3.0 5V/3A fast charge) plus 5 Type-A ports for media sticks, game controllers, and rear-seat displays. The -40C to +85C industrial temp grade survives cabin thermal swings, and the hub's robust BC1.2 support prevents inrush fault trips during engine crank. CAN-to-I2C bridging via companion MCU allows the head unit to surface USB events to the vehicle network.
Empfohlen
Embedded SBC USB Expansion Header
Single-board computers like industrial Raspberry Pi carriers expand their 1 USB OTG port to 5+ Type-A ports plus 1 Type-C upstream by stacking the USB7056-I/KDX over the carrier's high-speed connector. The integrated PD 3.0 controller negotiates 5V/3A or 12V/2A from a USB-C PD power supply, eliminating a separate PD chip on the carrier. The 100-VQFN reflow profile (JEDEC J-STD-020 MSL3) tolerates standard lead-free assembly on host SBC carriers.

Wichtigste Unterscheidungsmerkmale
- Integrated USB PD 3.0 controller on-chip (vs. TUSB7320RKMR)
- Industrial temperature grade (-40C to +85C) for ruggedized designs (vs. USB7056/KDX)
- 6 downstream ports in one chip versus external mux chain (vs. TUSB4041IPAPR)
Designhinweise
USB 3.2 Gen 1 SuperSpeed differential pairs must be routed with 85 ohm differential impedance, length-matched within 150 mils (3.81 mm) of the complementary pair, and isolated from other high-speed traces by at least 3W spacing. Keep upstream Type-C connector and downstream ports within 50 mm of the USB7056-I/KDX to preserve signal integrity; route over a continuous reference ground plane with no splits beneath SuperSpeed lanes.
Provide at least a 22 uF bulk and 100 nF high-frequency decoupling capacitor within 1 mm of each VDD33 pin, plus a 4.7 uF bulk on VBUS_UP. Add per-port VBUS load switches (e.g., TPS22918DBVR) if overcurrent protection is required above 500 mA, otherwise the internal switch handles BC1.2 CDP/SDP/DCP modes with default 500 mA / 1.5 A limits.
Do not omit the 25 MHz crystal or substitute an external CMOS clock without consulting the datasheet; the USB 3.2 Gen 1 PHY uses this clock directly and jitter above 50 ps RMS will fail USB-IF compliance. The RBIAS pin requires a 12.4 kohm 1% resistor to ground; using a different value shifts PHY drive strength out of spec. Route CC1/CC2 as 90 ohm differential on the Type-C upstream and 5.1 kohm Rp pull-up (or use Microchip's recommended configuration) - never leave CC floating on a Type-C port.
Compliance-Informationen
RoHS compliant per Microchip product page. Not AEC-Q100 qualified - design should use AEC-Q100 USB hub if specifically automotive-grade qualification is required.
