Description

Example Applications

Virtual Com Port Drivers

Interface Products

The CP2101 is a highly-integrated USB-to-UART bridge controller pro-

viding a simple solution for updating RS-232 designs to USB using a

minimum of components and PCB space. The CP2101 includes a USB

2.0 full-speed function controller, USB transceiver, oscillator, EEPROM

and asynchronous serial data bus (UART) with full modem control sig-

nals in a compact 5 x 5 mm QFN-28. No other external USB components

are required.
