CP2102 in Silicon Labs CP2102 / CP2104 Family
The CP2102 family by Silicon Labs consists of highly integrated USB-to-UART bridge controllers designed to provide a simple solution for updating RS-232 designs to USB. These fixed-function devices eliminate the need for complex firmware development by providing a complete plug-and-play interface. Each IC integrates a USB 2.0 full-speed function controller, USB transceiver, oscillator, and a universal asynchronous receiver/transmitter (UART) with modem control signals, making them a standard choice for basic serial communication in industrial and consumer electronics.
Variants in This Sub-Family
Variants within the CP2102 sub-family typically differ by packaging options and temperature ratings. The standard CP2102-GMR is provided in a QFN28 package and is rated for industrial temperature ranges (-40C to +85C). While the core silicon remains consistent, some specific ordering codes may denote tape-and-reel versus tube packaging or minor revisions in the internal ROM configuration for specific high-volume OEM customers.
