CP2102N-A02-GQFN28R USB-to-UART Bridge IC | USB 2.0 | 28-QFN | Silicon Labs

In embedded system development, industrial equipment debugging, or consumer electronics, connecting a traditional UART serial port to a modern computer's USB interface is a common yet cumbersome design hurdle. The CP2102N-A02-GQFN28R is designed to simplify this process as much as possible. This highly integrated bridge chip from Silicon Labs packs a USB 2.0 full-speed controller, transceiver, clock, regulator, and UART interface into a single 28-QFN package (5x5mm). It requires no external crystal and works with minimal external components, effectively reducing BOM cost and PCB footprint. The chip operates from a 3V to 3.6V supply across an industrial temperature range (-40°C to +85°C), supporting baud rates up to 3 Mbps. It is ideal for development boards, POS terminals, medical devices, and IoT gateways. We supply 100% original, new products with ample stock and fast delivery.
