The (often stylized as CBM2019 or simply “YC2019” in firmware tools) is a single-chip USB 2.0 flash drive controller that entered mass production in late 2019. Its name breaks down logically: “ChipY” appears to be their internal series for USB 2.0 mass storage, while “C2019” denotes the year of design finalization.
Because FirstChip controllers are highly affordable, they are the industry standard for unbranded flash drives, cheap bulk corporate gifts, and, unfortunately, "fake capacity" drives sold on online marketplaces (such as a drive advertised as 2TB that actually only holds 16GB of data).
