CP2102 USB to UART Bridge QFN28, 3V to 3.6V, 28 Pins

The CP2102 USB to UART Bridge provides a complete plug-and-play interface solution, offering a simple and reliable way to add USB connectivity to your embedded designs. This USB 2.0 compliant device comes with royalty-free drivers, ensuring seamless integration with minimal development effort.

With an integrated USB transceiver, no external resistors are needed, and the integrated clock removes the requirement for an external crystal, significantly reducing the external component count and simplifying your PCB layout. This makes the CP2102 an ideal choice for space-constrained applications.

The device includes an internal 1024-byte programmable ROM that allows you to customise the vendor ID, product ID, serial number, power descriptor, release number, and product description strings, giving you flexibility to tailor the device to your specific application needs.
