It talks to the upstream host over SMBus or SPI for configuration, which is the typical hook for an embedded system that needs to enumerate the hub's topology at boot without a dedicated EEPROM. Supplied in tray packaging, which is the standard for pick-and-place lines that run QFN strips — no reel fee, but the tray count sets the minimum order increment.","metaTitle":"Microchip USB5742B-I/2G USB 3.2 Hub Controller, 2-Port","metaDescription":"Microchip USB5742B-I/2G USB 3.2 hub controller, 2-port, SMBus/SPI interface, -40 to 85°C, 56-VQFN.
