Six-port USB 3.0 hub with onboard Cortex-M0
The CYUSB3326-88LTXCT is a 6-port USB 3.0 hub controller from Infineon's HX3 series, built around an ARM Cortex-M0 core. It handles the full USB 3.0 hub function — enumeration, packet routing, and port power management — while the embedded MCU lets you customise descriptor strings, vendor commands, and GPIO behaviour through the I²C interface.
88-QFN package and supply rails
Housed in an 88-VFQFN exposed-pad package (10x10 mm body), the part requires three supply domains: 1.14V–1.26V for the core, 2.5V–2.7V for the USB PHY, and 3V–3.6V for the I/O ring.
Active production — no end-of-life watch
ROHS3 compliant. The part is sourced per RFQ — confirm the BOM quantity and preferred packaging (Tape & Reel or Cut Tape) at quote time.
Commercial temperature — indoor use only
That covers desktop PCs, docking stations, monitors, and consumer electronics. Not rated for industrial enclosures or outdoor installations — if the system sees -20°C or 85°C ambient, this part will not hold the operating range.
