It comes in a 28-VFQFN exposed-pad package (supplier device package 28-QFN, 4x4 mm). The 4x4 mm footprint fits tight layouts where a larger QFP would not. CT works for prototypes or small-batch rework. Sourced through independent distribution — availability and current pricing confirmed at RFQ against your BOM quantity.","metaTitle":"Microchip UPD350CT/Q8X USB Controller, I²C, 28-QFN","metaDescription":"Microchip UPD350CT/Q8X USB 3.0 controller with I²C interface in 28-QFN (4x4 mm).
