Microchip’s USB connectivity solutions cover applications such as embedded systems, industrial equipment, automotive, laptop docks, monitors and AI peripherals, with a clearly structured product portfolio comprising four main categories: integrated SmartHub solutions, standalone USB-C PD port controllers, high-speed USB signal switches and USB PHY transceivers. All products are USB-IF certified and balance low power consumption, signal integrity, port power management and Alternate Mode expansion capabilities.

I. USB Hubs (USB Hub / SmartHub™)

Microchip’s hubs are divided into two main product lines: USB 2.0 MTT hubs and USB 3.2 Gen1/Gen2 SmartHubs. Unlike traditional hubs, SmartHubs feature a built-in 32-bit control core and an integrated bridging channel, which are their key differentiating features.

Core Series and Representative Models

1. USB 2.0 Hubs (USB4624, USB4715, USB84604 automotive grade)

The USB4624 and USB4715 are 4-port MTT (Multi-Transaction Transfer) USB 2.0 hubs supporting 480 Mbps high-speed data transfer. They integrate FlexConnect port switching capability and support the HSIC (High-Speed Inter-Chip) interface, making them suitable for embedded motherboards, printers and IoT gateways; The USB84604 is an AEC‑Q100 automotive-grade model designed for in-vehicle infotainment systems. It offers native support for CarPlay and Android Auto screen mirroring, enabling the transmission of audio and video signals whilst charging.

2. USB3.2 Gen1 SmartHub (USB7002)

A 4-port 5 Gbps SuperSpeed hub with a native Type-C upstream port, 2 downstream Type-C ports, 1 USB 3.2 port and 1 USB 2.0 port; features a built-in bridge controller enabling USB-to-I2C/SPI/UART/I2S/GPIO conversion, eliminating the need for additional bridge chips, and is suitable for docking stations, monitors and industrial all-in-one computers.

3. USB 3.2 Gen 2 SmartHub (USB705x Series)

10 Gbps data rate, integrated PD co-management logic, featuring two exclusive functions: HostFlexing (all Type-C ports can dynamically switch between host and device modes without the need for port identification) and PDBalancing port power balancing, which automatically allocates power when multiple ports are simultaneously outputting PD; dynamic current limiting and overheating protection make this the mainstream solution for multi-port docking stations; The USB7016 is a 6-port version, designed for multi-peripheral docks and industrial test equipment.

Key Features

- Offers OEM-customisable firmware configuration, allowing modification of port roles, Vconn and advertisement messages;

- Offers commercial-grade, industrial-grade and automotive-grade temperature options, suitable for in-vehicle and automation equipment.

Typical Applications

Laptop docks, in-vehicle multimedia headsets, industrial HMIs, Type-C monitor docks, POS terminals and standalone USB hub modules.

II. USB-C PD Controller (USB Type-C Power Delivery Controller)

Comprises standalone PD port controllers that can be used independently with a hub or SoC. Native support for USB-C PD 3.1, PPS programmable power, and EPR extended power (up to 100W), with support for DFP/UFP/DRP dual roles, Vconn power supply, and DisplayPort Alternate Mode negotiation.

Core Series and Representative Models

1. MCP22301: Stand-alone PD 3.1 Controller

A pure PD protocol stack controller without Type-C CC physical detection; used in conjunction with a CC detection device, it is suitable for high-power power adaptors and multi-port chargers. It features an open-source PDS firmware stack and supports fixed power, PPS, fault protection, and I²C control of downstream DC-DC buck-boost chips.

2. MCP22350: Highly Integrated Single-Port PD 3.1 Controller

Integrates CC pin detection, Vconn switch and PD protocol engine; features a compact package; performs Type-C identification and PD negotiation on a single chip, simplifying the BOM; supports DRP dual roles, allowing switching between power-supplying and power-consuming devices; suitable for portable energy storage, tablets and monitors.

3. UPD350 / UPD360 (Classic PD 3.0 Port Controllers)

Mature, mass-produced models widely used in PC motherboards, laptops and docking stations; the UPD360 supports charging without a battery (‘Dead Battery’ charging) and DisplayPort Alt Mode, and can be integrated with Microchip’s MEC series of EC embedded controllers, making it a classic solution for Type-C ports on laptop motherboards; Often paired with USB7002/USB705x hubs, with one hub port paired with a single UPD to implement a PD port.

4. UTC2000: Entry-level Type-C Controller

A simplified solution designed for low-cost charging docks and small household appliances that require only Type-C recognition and fixed 5V charging, without the need for advanced PD functionality.

Typical Applications

Type‑C fast-charging adaptors, laptop motherboards, in-car charging ports, all-in-one monitor connections, portable energy storage, and multi-port charging stations.

III. USB Switch (USB Switch / Signal Multiplexer)

Microchip USB switches are high-speed analogue signal multiplexers responsible for routing and switching USB differential signals (D+/D–) or SuperSpeed differential pairs. They do not perform protocol parsing but only select signal paths, offering high bandwidth and low insertion loss. They are used for signal sharing, host switching and port multiplexing.

Product Features

- USB 2.0 Switch: Bandwidth ≥ 1 GHz; supports 480 Mbps High-Speed USB 2.0; low parasitic capacitance and low on-resistance; extremely low quiescent power consumption; compact package; commonly available in 2-to-1 and 4-to-1 multiplexer configurations;

- USB 3.2 High-Speed Signal Switches: Optimised for SuperSpeed differential pairs; control impedance matching to reduce return loss and meet 5G/10G signal integrity requirements;

- Control Interface: Simple GPIO control; some models support I²C-programmable channel selection;

- Some models integrate power path switches, enabling synchronised operation between signal switching and VBUS power supply.

Typical Applications

- KVM switches: switching between multiple hosts using a single set of keyboard, mouse and USB flash drive;

- Motherboards / docking stations: time-division switching of multiple Type-C interfaces via a single PHY;

- USB signal routing for test fixtures and automated equipment;

- Internal USB channel switching in mobile phones and tablets, distinguishing between OTG and host modes.

IV. USB Transceivers (USB PHY Transceivers)

Microchip USB transceivers are USB physical layer (PHY) chips that perform serial/parallel encoding and decoding, differential signal driving, reception and impedance matching. They interface with the MCU/SoC link layer via a ULPI interface, enabling the expansion of USB high-speed interfaces without the need for a built-in USB PHY in the processor.

Representative models: USB3300, USB3320, USB334x series

- USB3300: Industrial-grade high-speed USB 2.0 PHY with a ULPI interface; features a simplified pinout, replacing traditional UTMI and significantly reducing I/O usage; supports 480 Mbps high-speed, 12 Mbps full-speed and 1.5 Mbps low-speed modes;

- USB3320: Enhanced single-supply ULPI PHY with flexible clocking options, supporting external crystal oscillators, resonators and ULPI input clocks; available in a compact 5×5 mm QFN package;

- Models cover commercial and industrial temperature ranges, with some automotive-grade versions designed for in-vehicle USB applications;

Key Features

- Integrated on-chip terminating resistors and ESD protection simplify peripheral matching circuits;

- Supports suspend/resume and LPM (Low Power Mode) standby;

- Standardised ULPI interface, compatible with the vast majority of ARM MCUs and FPGAs;

- Advantages of a standalone PHY solution: the host controller core need not incorporate USB functionality, facilitating the addition of USB capabilities to FPGAs, DSPs and general-purpose MCUs.

Typical Applications

FPGA development boards, industrial data acquisition modules, data loggers, embedded controllers, and in-vehicle USB peripherals.
