Product Summary

The CP2103-GM is a highly-integrated USB-to-UART Bridge Controller providing a simple solution for updating RS-232/RS-485 designs to USB using a minimum of components and PCB space. The CP2103-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 (sometimes called “MLF” or “MLP”). 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

CP2103-GM absolute maximum ratings: (1)Ambient temperature under bias: -55 to 125℃; (2)Storage Temperature: -65 to 150℃; (3)Voltage on any I/O Pin or RST with respect to GND: -0.3 to 5.8 V; (4)Voltage on VDD or VIO with respect to GND: -0.3 to 4.2V; (5)Maximum Total current through VDD, VIO, and GND: 500mA; (6)Maximum output current sunk by RST or any I/O pin: 100mA.
