Interface Products
The CP2103 is a highly-integrated USB-to-UART bridge controller pro-
viding a simple solution for updating RS-232 or RS-485 designs to USB
using a minimum of components and PCB space. The CP2103 is a func-
tional upgrade to CP2101/2 with new features such as configurable I/O
levels (3.3 to 1.8 V) and four general purpose I/O signals for system sta-
tus and control.
It includes the standard 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 MLP-28
package. No other external USB components are required.
