Product Summary

The CP2102-GM is a highly-integrated USB-to-UART Bridge Controller providing a simple solution for updating RS-232 designs to USB using a minimum of components and PCB space. The CP2102-GM includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, EEPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5 x 5 mm QFN-28 package. The CP2102-GM UART interface implements all RS-232 signals, including control and handshaking signals, so existing system firmware does not need to be modified.
