Product Summary

The CP2102-GMR is a single-chip 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-GMR 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 × 5 mm QFN-28 package. No other external USB components are required. The on-chip EEPROM may be used to customize the USB Vendor ID, Product ID, Product Description String, Power Descriptor, Device Release Number, and Device Serial Number as desired for OEM applications.

Parametrics
