... System Overview The CP2105 is a highly-integrated USB-to-Dual-UART Bridge Controller providing a simple solution for updating RS-232 designs to USB using a minimum of components and PCB space. The CP2105 includes a USB 2.0 full- speed function controller, USB transceiver, oscillator, one-time programmable ROM, and two asynchronous serial data buses (UART) with full modem control signals in a compact QFN-24 package (sometimes called “ ...

... USB Reset signal is detected device reset occurs. On exit of Suspend mode the SUSPEND signal is de- asserted. SUSPEND is weakly pulled to VIO in a high impedance state during a CP2105 reset. If this behavior is undesirable, a strong pulldown (10 k) can be used to ensure SUSPEND remains low during reset. ...

... Communications Interface Only one mode can be selected for each interface. Also, the mode of the CP2105 can only be configured once and cannot be reset to the default configuration after being programmed. Refer to “AN223: Port Configuration and GPIO for CP210x” for more information on how to configure the port pins of the CP2105. ...

... GPIO pins. To use the pins as GPIO pins, the interface with the GPIO pins must be configured in GPIO Mode. By default, both communication interfaces on the CP2105 are configured for GPIO Mode. If the Modem Control signals are needed, the interface must be configured for Modem Mode. See Section 7 for more information on Modem Mode ...

... One-Time Programmable ROM The CP2105 includes an internal one-time programmable ROM that may be used to customize the USB Vendor ID (VID), Product ID (PID), Product Description String, Power Descriptor, Device Release Number, Interface Strings, and Device Serial Number as desired for OEM applications. If the programmable ROM has not been programmed, the default configuration data shown in Table 13 and Table 14 is used ...

... CP2105 10. Voltage Regulator The CP2105 includes an on-chip 5 to 3.45 V voltage regulator. This allows the CP2105 to be configured as either a USB bus-powered device or a USB self-powered device. A typical connection diagram of the device in a bus- powered application using the regulator is shown in Figure 8. When enabled, the voltage regulator output appears on the V pin and can be used to power external devices ...
