2.3. 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 voltages 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)
2.4. I/O Power Supply
FPGA banks are divided into two groups as follows.

CNB I/O
I/O power of CNA, IOA, is supplied by on-board 3.3V.
I/O power of CNB, IOB, is supplied by external power input.
When JP1 is short, on-board 3.3V is supplied to VIO(B).

EDX-303 v1.0
2.5. Oscillator
50MHz oscillator (U1) is equipped as on-board clock. External clock
can be input from user I/O connectors.
For more detail, please refer to circuit schematics.
2.6. User Switch
A push switch (SW1) and a DIP switch (SW1[2])
are equipped as user switch. They are pulled up, so
you can input low level signal to the FPGA when you push it.
2.7. User LED and 7-Segment LED
They are user LEDs. They are lighted by output low.
2.8. MRAM
This is a non-volatile memory for SRAM control.
For more details, please refer to the datasheet of the memory.
2.9. Debug I/F
CN2 can be used for any purpose.
They are connected through resisters to FPGA.
2.10. Setting Switch
FPGA configuration mode can be changed by this switch.

2.11. FT2232H Setting Jumper
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 JP4, reset function and EEPROM are available.
JP4 [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 ).
JP4 [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 BBC[EDX-303] set this
open
3. Device Driver
To recognize USB controller, installing device driver is needed. The first time
EDX-303 is connected to a PC, installing it is required by Operation System.
The device driver is available at the support page.
