YINGHUA USB82640AMR IC semiconductor

The YINGHUA USB82640AMR is a new semiconductor component supplied in a VQFN48 package. It serves engineers and designers integrating USB interface logic into custom circuit boards. The part is categorised under ICs Semiconductors for general electronic assembly. It is not suited for buyers seeking a finished peripheral or a module with pre-installed firmware.

Sustained load behaviour VQFN48 package

The VQFN48 package provides a thermal pad that conducts heat toward the printed circuit board during continuous operation. Stable performance relies on adequate copper area and via stitching beneath the device. Without proper board-level thermal design, the IC may throttle or exceed its safe junction temperature. No active cooling provision is included with the bare component.

Installation notes VQFN48 footprint

Installation requires reflow soldering onto a matching 48-pin VQFN footprint with an exposed central pad. Hand soldering is impractical due to the leadless outline and thermal pad accessibility. Common issues include insufficient solder paste on the thermal pad, misalignment causing shorts, and voids that degrade thermal transfer. Automated optical inspection is recommended after placement.

Questions about this item

How much heat does the USB82640AMR VQFN48 generate when running continuously?

The USB82640AMR VQFN48 is a semiconductor IC; its thermal output depends on the circuit design and load conditions in your application.

What external components are required for the USB82640AMR VQFN48 to function?

As a bare IC in a VQFN48 package, the USB82640AMR needs a printed circuit board with power regulation, decoupling capacitors, and any protocol-specific circuitry your design requires.

Can the USB82640AMR VQFN48 be soldered onto a board designed for older 48-pin VQFN parts?

Yes, the USB82640AMR uses a standard VQFN48 footprint, so it fits existing 48-pin VQFN land patterns if the pinout matches your schematic.
