USB2524-ABZJ IC Semiconductor

The YINGHUA USB2524-ABZJ is a new semiconductor component packaged in a VQFN56 format. It is intended for engineers and designers integrating USB hub or controller functions into electronic assemblies. The device is listed as an IC semiconductor type suitable for circuit-level implementation.

For USB hub integration projects

This component suits developers building multi-port USB hub boards or embedded USB connectivity. It is not for buyers who need a finished peripheral with cables and an enclosure. It is also not for users who require a plug-and-play hub for immediate computer use without circuit design work.

VQFN56 package with 56 contacts

The 56-contact VQFN package provides the pin count needed for four downstream USB ports and associated control signals. It comfortably handles standard hub signalling and power distribution tasks defined by the part specification. Designs needing a higher port count or a different package footprint will require an alternative device.

Questions about this item

What circuit-board footprint must my PCB provide for the USB2524-ABZJ VQFN56 to solder correctly?

The chip uses a VQFN56 package, so your board needs a matching 56-pin very-thin quad flat no-lead footprint with the correct pad pitch and thermal pad.

Will the USB2524-ABZJ VQFN56 operate alongside legacy USB 2.0 peripherals I keep on the same hub?

As a USB 2.0 hub controller it negotiates at high-speed, full-speed or low-speed, so older mice, keyboards or printers will enumerate normally on its downstream ports.

How can I confirm the USB2524-ABZJ VQFN56 is functioning after power-up?

Check that the upstream port enumerates as a hub descriptor, all four downstream ports report connected devices, and the SUSPEND pin toggles when the bus enters low-power state.
