Microchip announces the USB58xx and USB59xx next-gen families of SmartHubs. These are the first seven-port USB 3.1 Gen1 hub ICs available in the market today and offer customers simpler designs and cost savings over previous solutions. These families of hub ICs offer manufacturers multiple direct interfaces to USB Type-C connectors for enabling 5 Gbps USB data rates in a single integrated circuit.

The USB58xx and USB59xx families are ideal for applications such as monitors, docking stations, digital televisions, set-top boxes and computing peripherals. These applications benefit from the expanded number of external USB 3.1 Gen1 ports available for data connections within a single, monolithic device.

Having a hub IC that supports seven ports avoids the power and cost problem of tiering two four-port devices to provide sufficient downstream ports for end-customer applications. A single chip results in a simpler design, cost savings and reduced component footprint.

In addition, Microchip’s proprietary SmartHub technology can further reduce BOM cost by enabling I/O bridging and FlexConnect for expanded USB hub functionality without adding any additional components.

Microchip enables multiple, direct USB Type-C connections through integrated 2:1 multiplexers which supports the reversible connection feature of the USB Type-C connector. In addition, the devices can expand beyond seven ports through PortSplitting, which allows embedded applications to only use the interface needed for their internal USB connection.

Each device also has built-in Billboard support for notifying users when an unsupported device has been connected in a USB Power Delivery application. In addition, the USB58xx and USB59xx families are supported by Microchip’s USBCheck, a free engineering service for reviewing schematics and layout designs.

The product families support a range of solutions based on the application requirements for USB Type-C interfaces. The USB59xx family supports direct upstream interface of USB Type-C, while the USB58xx provides support for legacy, non-USB Type-C interfaces. Both families support legacy battery charging including BC1.2, Apple® devices and many non-standard devices available in the market today.

The USB58xx and USB59xx families are available for sampling and volume production now. The USB58xx family features four devices whilst USB59xx family features three devices. Both families are available in 100-pin QFN packages in industrial and automotive grades.
