CP2104 Classic USB Bridge

Note: The CP2104 is not recommended for new designs. For newer designs, the CP2102N devices offer compatible footprints and are recommended for use instead of the CP2104. The CP2104 UART to UART Bridge provides a complete plug and play interface solution that includes royalty-free drivers. This USB 2.0 compliant device includes 4 digital I/O pins and is availble in a 4x4 mm QFN24 package.
