MANUFACTURER PART RECORD

CH9102F

The CH9102F is a WCH (Qinheng) USB-to-serial UART bridge in the QFN-24 4x4 mm package, with a hardware full-duplex UART supporting baud rates up to 4 Mbps. It adds a USB port to microcontroller products and upgrades legacy serial equipment to USB without redesigning the serial firmware, which shortens development time for debug consoles, programming interfaces and industrial serial adapters. Selection advice: in the CH9102 datasheet variant table, the F suffix is exactly this QFN-24 package — the CH9102X sibling is a larger QFN-28 and is not footprint-compatible, so match the full CH9102F code to your PCB layout before ordering. Parameters verified against WCH documentation.
