2.4. Clock
An oscillator, 50 MHz, is equipped as on-board clock. External clock can be input
from user I/Os.
For more details, please refer to the circuit schematics.
2.5. Power Supply
This board operates from single DC 5.0 V power supply from user I/O connectors
(CNA and CNB). The external power supply should be sufficient and stabilized.
Please do not apply over 5.0V voltage. Internally required 3.3[V] and 1.2[V] are
generated by on-board voltage regulators.
You can also use USB bus power by setting JP2.
1-3, 2-4: Short (factory setting)
Powered from user I/O connectors only
1-2, 3-4: Short
Powered by USB bus power and user I/O connectors
(Depending on FPGA design, power current may be
insufficient in USB only powering)
2.6. I/O Power Supply
FPGA banks are divided into two groups as follows.

2.7. USB Controller
FTDI’s FT2232H is mounted as USB controller IC. By connecting to a PC, 2
channels (A/B) are recognized.
Chanel A is connected to user ports of the FPGA for user communication. Chanel B
is connected to pins for FPGA configuration ports.
By setting JP3, reset function and EEPROM are available.
JP3 [1-2]
Short (factory setting)
EEPROM for FT2232H is available
Open
EEPROM for FT2232H is disabled.
- FT2232H will be recognized in default setting.
(FTDI default descriptor, both A/B channels are
configured as UART mode ).
JP3 [3-4]
Short
FPGA pin is connected to FT2232H’s reset input
pin
- By setting FPGA pin to High, FT2232H will be
in its reset mode.
Open (factory setting)
FPGA pin is not connected to FT2232H’s reset pin
- To use original configuration tool, set this open

2.8. Device Driver
To recognize USB controller, installing device driver is needed. The first time
EDX-301 is connected to a PC, installing it is required by Operation System.
The device driver is available at the support page.
2.9. DIP Switch (SW1)
SW1[2] is a user switch. X_M1 is connected to M1 pin of FPGA. It is used for the
configuration mode switching.
SW1
ASW2[2] X_M1[1] Configuration Mode
X ON Master Serial / SPI
X OFF USB / JTAG
ON: Low (0), OFF: High (1), X: Don't Care
z Master Serial / SPI mode
Use this mode to configure the FPGA by the configuration device when it is
powered on.
z USB / JTAG mode
Use this mode to configure the FPGA from a JTAG I/F or USB I/F using
“BBC[EDX-301]”. You can use this mode to avoid the FPGA being configured by
the configuration device.

3.2. Using JTAG Download cable
Download cable is needed to use XILINX tool (iMPACT and ChipScope). Pin
assignment is as follows.
Pin No. Signal Name Direction
1 GND I/O
2 TCK IN

4 TMS IN
5 VCC(3.3V) OUT
6 TDI IN
7 GND I/O

3.3. Using Configuration Device
Configuration data written in the configuration device will be configured to the
FPGA automatically when power is applied. To use this function, set configuration
mode to “Master Serial / SPI”.
Do not download inaccurate configuration data. It would damage the FPGA and
peripheral circuit.
