... The USB Suspend and Resume signals are supported for power management of both the CP2103 device as well as external circuitry. The CP2103 will enter Suspend mode when Suspend signaling is detected on the bus. On entering Suspend mode, the CP2103 asserts the SUSPEND and SUSPEND signals. SUSPEND and SUSPEND are also asserted after a CP2103 reset until device configuration during USB Enumeration is complete ...

... Asynchronous Serial Data Bus (UART) Interface The CP2103 UART interface consists of the TX (transmit) and RX (receive) data signals as well as the RTS, CTS, DSR, DTR, DCD, and RI control signals. The UART supports RTS/CTS, DSR/DTR, and X-On/X-Off handshaking. The UART is programmable to support a variety of data formats and baud rates. If the Virtual COM Port drivers are used, the data format and baud rate are set during COM port configuration on the PC ...

... Voltage Regulator The CP2103 includes an on-chip voltage regulator. This allows the CP2103 to be configured as either a USB bus-powered device or a USB self-powered device. These configurations are shown in Figure 7 and Figure 8. When enabled, the 3 V voltage regulator output appears on the V devices. See Table 10 for the voltage regulator electrical characteristics. ...
