The Silicon Labs CP2104 is a highly integrated USB-to-UART bridge controller designed to simplify serial communication between USB hosts and embedded systems. It supports USB 2.0 full-speed operation and provides reliable UART interfaces with data rates up to 2 Mbps. The CP2104 integrates an internal oscillator, EEPROM, voltage regulator, and USB termination resistors, reducing external component count and board space. It is widely used in development boards, IoT devices, industrial controllers, and consumer electronics. With strong driver support for Windows, macOS, and Linux, the CP2104 enables quick plug-and-play connectivity and stable data transfer in compact, low-power designs.
