3.1. USBXpress Driver Development Kit

The Silicon Laboratories USBXpress

Development Kit provides a complete host software solution for interfacing to

CP210x devices. No USB protocol or host device driver expertise is required. Instead, a simple, high-level Application

Program Interface (API) for the host software is used to provide complete USB connectivity. The USBXpress

Development Kit includes Windows device drivers, Windows device driver installer, host interface function library

(host API) provided in the form of a Windows Dynamic Link Library (DLL). See Application Note AN169, “USBXpress

Programmer’s Guide” for detailed information on using the USBXpress drivers.

The USBXpress drivers are available here: www.silabs.com/usbxpress.

Click the USBXpress Development Kit link in the Download for Windows 2000/XP/Server 2003/Vista/Win7 section

to download the USBXpress drivers. Run the installer and follow the steps to install the software to the desired

CP2104-EK

2 Rev. 0.7

location. The default installation directory is C:\SiLabs\MCU\USBXpress_SDK.

Further installation instructions for the WinCE drivers can be found in the ReadMe.txt file contained inside the

driver package.

4. CP2104 Hardware Interface

The evaluation board is connected to a PC as shown in Figure 1.

1. Connect one end of the USB cable to a USB Port on the PC.

2. Connect the other end of the USB cable to the USB connector on the

CP2104 evaluation board.

3. Connect one end of the RS232 serial cable to the DB-9 connector on the

CP2104 evaluation board

4. Connect the other end of the RS232 serial cable to the target serial device.

5. CP2104 Software Interface

If the Virtual COM Port drivers are used, the CP2104 will appear as a COM port in the Device Manager, as shown

in Figure 2. The CP2104 will always use the lowest available COM port for operation. For instance, if COM ports 1

and 2 are in use by other peripherals and applications, the CP2104 will use COM 3.

The CP2104 functions identically to a COM port from the reference point of both the host application and the serial

device, and it can support serial device control requests defined in the Microsoft Win32®Communications API.

Examples for how to communicate with the device as a serial COM port are included in AN197 on the

www.silabs.com/interface-appnotes page or in the SDK.

If the USBXpress drivers are used, the CP2104 will appear as a USB USBXpress device as shown in Figure 2.

Examples for how to communicate with the device using the USBXpress interface are included in AN169 on the

www.silabs.com/interface-appnotes page.

6. Evaluation Board

The

CP2104

Evaluation Kit includes an evaluation board with a

CP2104

device pre-installed for evaluation and pre-

liminary software development. Numerous input/output (I/O) connections are provided to facilitate prototyping using

the evaluation board. Refer to

Figure 3

for the locations of the various I/O connectors.

P1 USB connector for USB interface

P2 DB9 connector for RS232 interface

J1 UART signal access connector

J2, J3 GPIO access connector

J4 Power connector

DS0–DS3 Green GPIO LEDs

DS4 Red SUSPEND indicator LED

6.1. LED Headers (J2, J3)

Connectors J2 and J3 are provided to allow access to the GPIO pins on the CP2104. Place shorting blocks on J2

and J3 to connect the GPIO pins to the four green LEDs DS0–DS3. These LEDs can be used to indicate active

communications through the CP2104. Table 1 shows the LED corresponding to each header position.

6.2. Universal Serial Bus (USB) Interface (P1)

A Universal Serial Bus (USB) connector (P1) is provided to facilitate connections to the USB interface on the

CP2104. See Table 2 for the USB pin definitions.

6.3. UART Signals (P2, J1)

An RS232 transceiver circuit and DB9 connector (P2) are provided on the evaluation board to connect the CP2104

virtual serial port to external serial devices. See Table 3 for the RS232 P2 pin descriptions. The J1 connector is

provided to facilitate direct access to the CP2104’s UART signals. Shorting blocks on J1 are required to connect

the UART signals to P2. See Table 4 for J1 pin descriptions.

6.4. Power Connector (J4)

This header (J4) is included on the evaluation board to provide several power options. The following describes the

function of each pin:

Pins 1–2: Connects CP2104 VIO input (Pin 5) to CP2104 VDD (Pin 6). Remove the shorting block to power

VIO from an external source.

Pins 3–4: Connects the main +3 V net to the CP2104 VDD (Pin 6). The main +3 V net powers the other

components (four green LEDs and RS232 Sipex Part) on the evaluation board.
