CYUSBS234 QUICK START GUIDE
Step 2: Powering the Board*
• Connect the board to the PC using the USB cable
• LEDs D2 and D4 glow to indicate that the board
is powered
Step 1: Software Installation
• Download and unzip the ISO le from
www.cypress.com/go/CYUSBS234
• Run cyautorun.exe and follow the steps in the
installer window
• Install Tera Term from the following location:
<Install directory>/Cypress/CYUSBS234 DVK/
1.0/teraterm
Step 3: Enumeration
• The device appears as a USB Serial Port (COM#)
in the Device Manager. (To launch the Device Manager
in Windows 7, click Start and type Device Manager in
‘Search programs and les’ box)
Step 4: Testing Basic UART Functionality
• Connect J15.3 (TXD) to J15.2 (RXD) with the provided
jumper wire
as shown above
• Run Tera Term (Start > All Programs > Tera Term)
• Click Serial and select Port (COM#) in the 'Tera Term:
New Connection' window, and then click OK
• Enable local echo option (go to Setup > Terminal
and check the local echo box)
• Type 'HELLO WORLD'. The text appears on the same
terminal and each character appears twice -
'HHEELLLLOO WWOORRLLDD'
* Connect the board to the PC only after software installation. For the latest software updates on
Windows, Linux, MAC, and Android, visit www.cypress.com/go/usbserial

Step 5: 10-MB File Transfer at 1 Mbps, with no Data Loss
• Connect J15.3 (TXD) to J15.2 (RXD) and J15.7 (RTS)
to J15.8 (CTS), with the provided jumper wires
• Go to Setup > Serial Port in the Tera Term window,
and enter 1000000 in the baud rate box. Select
Hardware in the Flow control drop-down menu; go to
Setup > Terminal > Receive and select CR+LF.Click OK
• Enable le capture: go to File > Log; uncheck Append
and select <le name> to save the received data
• Go to File > Send File and select the Test.txt le from
<Install directory>\Cypress\CYUSBS234 DVK\1.0
• The 'Tera Term: Send le' window shows effective
data throughput; multiply by 2X to get uni-directional
throughput
• Compare Test.txt and received le, using any le
compare utility to verify data integrity

Step 7: USB–I2C Bridge Conguration
• Click the SCB tab. Select I2C from the drop-down menu
and click the Program button. The 'Program succeeded’
message appears. Click OK to continue
• Click the Disconnect button to disconnect the board
from the conguration utility
• Press the reset switch, SW3 (refer to the gure in
step 13). The board enumerates as an I2C bridge
• Set jumpers J17 and J20 as shown in the gure above
to connect I2C EEPROM to the CY7C65211 device
Step 6: Device Connection to Conguration Utility
• Run the conguration utility from Start > All Programs
> Cypress > CYUSBS234 DVK > USB Serial
Conguration Utility
• Click the Select Target tab. Select the device
USB-Serial (Single Channel) Vendor MFG from the
drop down menu and click Connect
Step 8: USB–I2C Test Utility
• Run the USB Serial Test Utility from Start > All
Programs > Cypress > CYUSBS234 DVK >
USBSerialTestUtility
• Change the Product ID to 0004 to match the default
Cypress PID. The test utility lists the I2C interface on
the board. Click OK to continue

Step 9: USB–I2C Bridge Testing
• Click the Write data button. Data gets written at the
default EEPROM page address
• Click the Read & verify data button. When the received
and transmitted data is identical, the ‘Data verication
successful’ message appears at the bottom of the
window. The test proves successful data transfer with
the I2C interface

Step 12: USB–SPI Bridge Testing
• Click the Write data button. Data gets written at the
default EEPROM page address
• Click the Read & verify data button. When the received
and transmitted data is identical, the ’Data verication
successful’ message appears. The test proves successful
data transfer with the SPI interface

Step 10: USB–SPI Bridge Conguration
• Repeat step 6
• Click the SCB tab. Select SPI from the drop-down menu
and click the Program button. The 'Program succeeded’
message appears. Click OK to continue
• Click the Disconnect button. Press the reset switch, SW3
(refer to the gure in step 13). The board enumerates
as an SPI bridge
• Set jumpers J17, J19, J20, and J21 as shown above
10
Step 13: CapSense Button
• Touch the CapSense®button B1, as shown in the gure.
The D7 LED glows to indicate that the button is sensed
• Remove the nger from the B1 CapSense button and
the LED turns OFF to indicate that the button is released

LED D7 SW3
Step 11: USB–SPI Test Utility
• Run the USB Serial Test Utility from Start > All
Programs > Cypress > CYUSBS234 DVK >
USBSerialTestUtility
• Change the Product ID to 0004 to match the default
Cypress PID. The test utility lists the SPI interface
available on the board. Click OK to continue

CYUSBS234 QUICK START GUIDE
Note: By default, the SCB conguration jumpers are set for the USB-UART bridge as shown above. Refer to the
Table 3-1 in the kit guide for additional information on default jumper settings.
Kit operation: The CY7C65211, USB-Serial bridge controller can be congured as an USB-UART bridge,
an USB-I2C bridge, or an USB-SPI bridge. As an USB-UART bridge, data is transmitted from USB to UART (TXD).
TXD-RXD loop back connection enables the data to be fed back to the UART (RXD) to USB and is displayed
on the Tera Term window. The CY7C65211 controller also supports battery charger detection and congurable
CapSense functionality, providing best-in-class signal-to-noise ratio (SNR) and water-tolerance
