SmartHub™ ICs

Flexible USB SmartHub™ Bridge ICs

A SmartHub IC is a USB hub that integrates system-level functions typically associated with a separate microcontroller (MCU) or processor. It provides an extra port to handle host communication outside of USB. This enables the host to interact with peripheral components under the USB umbrella without the need for special bridge ICs. The downstream port used with the external bridge IC can now be made available for other USB functionality. We offer USB 2.0 and USB 3.2 SmartHub ICs that feature I/O bridging and FlexConnect port swapping and switching technologies to deliver expanded functionality, provide a more robust data interface and reduce BOM cost for applications such as:

Sub-system connectivity (wireless modules, POS peripherals, GPIO)
Laptop docks
PC monitor docks
Multi-function USB 3.2 Gen 1 peripherals

Why Choose a SmartHub IC?

Expands I/O capabilities beyond traditional USB 2/3 signaling
Integrates functionality to reduce BOM costs
Simplifies hardware design
Provides flexibility to switch host connectivity between ports as needed
Offers One-Time Programmable (OTP) memory for customization of hub ports
Supported by MPLAB^® Connect Configurator for customization and mass programming of devices
Available configuration straps eliminate the need to program devices at all

Key Functions of SmartHub ICs

Bridging Over USB for I/O Expansion

Enables the host to communicate to a non-USB peripheral over USB through a simple set of APIs
- I²C, SMBus, SPI, UART, GPIO
Saves the added expense of using a separate bridging IC to manage the non-USB peripheral
Eliminates the need to use a downstream USB port to interface to the bridging IC

Dynamic Host Switching: FlexConnect Feature

Enables system to be configured to switch between two USB hosts
- Switch can be enabled through a GPIO pin, a USB host command or via pre-boot configuration code
- Remaining downstream devices will re-enumerate with new host once switch has been made
Saves the added expense of using a separate 2:1 switch outside the hub
Simplifies implementation through use of dedicated GPIO pins and the ability to set registers or use custom APIs
