Overview
The board features the Efinix® T20 programmable device in a 256-ball FBGA package, which
is fabricated using Efinix® Quantum™ technology. The Quantum™-accelerated programmable
logic and routing fabric is wrapped with an I/O interface in a small footprint package. T20
devices also include embedded memory blocks and multiplier blocks (or DSP blocks). You
create designs for the T20 device in the Efinity® software, and then download the resulting
configuration bitstream to the board using the USB connection.
Note: For more information on T20 FPGAs, refer to the T20 Data Sheet, which you can download in our
Support Center under Docs (www.efinixinc.com/support/).
Figure 2: Trion™ T20 BGA256 Development Board Components
Trion T20 BGA256 Development Kit User Guide
The FTDI FT2232H module has two channels to support SPI (FTDI interface 0) and
JTAG (FTDI interface 1) configuration. It receives the T20 configuration bitstream from a
USB host and writes to the on-board SPI NOR flash memory. After a reset in SPI passive
mode, the FTDI controller can also write the configuration bitstream directly to the
FPGA. Additionally, it supports direct JTAG programming mode in which it writes the
configuration bitstream directly to the FPGA through the JTAG interface.
Note: Refer to AN 006 Configuring Trion FPGAs for more information.
www.efinixinc.com 5
Trion T20 BGA256 Development Kit User Guide
The SPI NOR flash memory stores the configuration bitstream it receives from the FTDI
FT2232H module. The T20 device accesses this configuration bitstream when it is in active
configuration mode (default).
The SDRAM device provides 256 Mb of memory and has a 16-bit data bus with 4 banks.
The board's main power supply is the 5V DC input. You must use your own DC power
supply to provide the board with power through the 5 V input jack. The recommended
power input is a 5 V (4 A maximum) DC power source. You can also power the board
through the micro USB port for designs with low power consumption (< 500 mA).
The board regulates down the 5 V DC input using on-board switching regulators to provide
the necessary voltages for the T20 device, SPI flash memory, SDRAM and on-board
oscillator.
Power On
To turn on the development board, turn on switch SW2. Upon power-up, the 5 V DC power
supply or micro-USB power is input to the on-board regulators through 5 V input jack
(CON1) to generate the required 3.3 V, 2.5 V, 1.8 V, and 1.2 V for components on the board.
When these voltages are up and stable, the board asserts a PWR OK signal (pulled high) from
the components' respective regulators. When the board asserts the PWR OK signal, a green
LED (D105) turns on, giving you a visual confirmation that the power supplies on the board
are up and stable.
Note: The micro-USB power supply powers up the board with limited current supply. Efinix recommends that
you use an external DC 5 V DC supply if your user design requires high power.
Reset
The T20F256C device is typically brought out of reset with the CRESET signal. Upon power
up, the T20F256C device is held in reset until CRESET toggles high-low-high.
Note: You can manually assert the high-low-high transition with pushbutton switch SW1.
CRESET has a pull-up resistor. When you press SW1, the board drives CRESET low; when
you release SW1, the board drives CRESET high. Thus, a single press of SW1 provides the
required high-low-high transition.
After toggling CRESET, the T20F256C device goes into configuration mode and reads the
device configuration bitstream from the flash memory. When configuration completes
successfully, the device drives the CDONE signal high. CDONE is connected to a green LED
(D1), which turns on when the T20F256C device enters user mode.

Clock Sources
Two on-board oscillators, 50 MHz and 74.25 MHz, are available to drive the T20F256C PLL
input pin and clock input. Alternatively, you can disable the 50 MHz oscillator and use an
external clock source through the SMA input (J5). Set jumper J3 to use the 50 MHz or SMA
input as the clock source.

Headers H7 and H8
H7 and H8 are 6-pin headers. You use a shunt across 2 pins to select 3.3 V, 2.5 V, or 1.8 V
for the T20F256C bank VCCIO1B_1C and VCCIO1D_1E, respectively, from the on-board
regulators.
By default, the board ships with a shunt connecting pins 5 and 6 to supply 3.3 V.

LEDs (D3 - D10)
Efinix® preloads the Trion™ T20 BGA256 Development Board with a demonstration design
that operates the LEDs. The board receives power through USB cable. Follow these steps to
run the design:
1. Connect the 5 V DC power source or USB cable to the board and to your computer.
2. Turn on the power switch (SW2). LED D105 (PWR OK) turns on, indicating that the
board is receiving power correctly.
Note: The Trion™ T20 BGA256 Development Kit does not include a DC power
adapter.
• While configuration is in process, the configuration done LED D1 (CDONE) turns
OFF to indicate the device is in configuration mode.
• At the same time, the LED D2 (NSTATUS) turns ON to indicate there is no
configuration error.
• When configuration completes, the configuration done LED (D1) turns on again. Four
green LEDs (D3 - D10) turn on, sweeping from D3 to D10 in ascending order.
