Overview
Thank you for choosing the Trion™ 8 BGA81 Development Kit (part number:
T8F81C-DK), which allows you to explore the features of the T8 FPGA.
Warning: The board can be damaged without proper anti-static handling.
What's in the Box?
The Trion™ 8 BGA81 Development Kit includes:
•Trion™ 8 BGA81 Development Board preloaded with a demonstration design
•4 standoffs
•4 screws
•3 foot mini-USB cable (type B)
Software Requirements
To develop your own designs for the T8 device on the board, you must install the
Efinity™ software. You can obtain the software from the Efinix™ Support Center
under Downloads (www.efinixinc.com/support/).
Note: The Efinity™ software includes tools to program the device on the
board. Refer to the Efinity™ Software User Guide for information about
how to configure the device.
Learn more: Efinity™ documentation is installed with the software (see
Help > Documentation) and is also available in the Support Center
under Docs.
Installing Standoffs
Before using the board, attach the 4 standoffs to the board with the screws
provided in the kit.
Warning: The board can be damaged if you over tighten the
screws. Tighten all screws to a torque between 4 ± 0.5 kgf/cm and
5 ± 0.5 kgf/cm.
Running the Demonstration Design
Efinix™ preloads the Trion™ 8 BGA81 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 USB cable to the board and to your computer. LED D1 turns
on briefly and then turns off, indicating that the board is receiving power
correctly. All other LEDs are turned off.
www.efinixinc.com 3

Trion 8 BGA81 Development Kit User Guide
When configuration completes, the configuration done LED (D8) turns
on briefly and then turns off. Four green LEDs (D2, D3, D5, D6) turn on,
sweeping in one direction.
Note: If LED D1 does not turn off, the board is not receiving power
correctly from the computer via the USB cable.
2. Press and hold pushbutton SW3. The LED sweep direction changes and LED
D7 turns on.
3. Press and hold pushbutton SW2 (reset) to turn off all LEDs.
Board Functional Description
The Trion™ 8 BGA81 Development Board contains a variety of components to
help you build designs for the Trion™ T8 device.

Overview
The board features the Efinix™ T8 programmable device, 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. T8 devices also include embedded memory blocks and multiplier blocks
(or DSP blocks). You create designs for the T8 device in the Efinity™ software, and
then download the resulting configuration bitstream to the board using the USB
connection.
Note: For more information on T8 FPGAs, refer to the T8 Data
Sheet, which you can download in our Support Center under Docs
(www.efinixinc.com/support/).

External Devices
The Atmel microcontroller has a built-in USB controller; it receives the T8
configuration bitstream from a USB host and writes to the on-board SPI NOR
flash memory. The microcontroller can also write the configuration bitstream
directly to the device when it is configured to boot in passive mode.
The SPI NOR flash memory stores the configuration bitstream it receives from
the microcontroller. The T8 device accesses this configuration bitstream when it is
in active configuration mode (default).
The board's main power supply is the 5 V DC (500 mA) it receives from the USB
interface. The board regulates down the 5 V DC using on-board low dropout
regulators to provide the necessary voltages for the T8 device, SPI flash memory,
and on-board oscillator.
Power On
Upon power-up, the USB power supply is input to the on-board regulators to
generate the required 3.3 V, 2.5 V, 1.8 V, and 1.1 V for components on the board.
When these voltages are up and stable, the board asserts a “power good” signal
(pulled high) from the components' respective regulators. This power good signal
triggers the Atmel microcontroller to bring the T8F81C device out of reset.
The power good signal is also connected to a green LED (D1). By default, the
power good signal is pulled low, and the LED is turned off. When the board
asserts the power good signal, the LED turns on, giving you a visual confirmation
that the power supplies on the board are up and stable.

Trion 8 BGA81 Development Kit User Guide
Reset
The T8F81C device is typically brought out of reset with the CRESET signal.
Upon power up, the T8F81C device is held in reset until CRESET toggles high-
low-high. CRESET is connected to the Atmel microcontroller, therefore, firmware
can control the high-low-high transition. If you have not loaded firmware into the
Atmel microcontroller, 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 T8F81C 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 (D8), which turns on when the T8F81C
device enters user mode.
Clock Sources
You can clock the T8F81C device using the 33.333 MHz oscillator, which drives
the T8F81C PLL IN pin. Alternatively, you can disable the 33.333 MHz oscillator
and source the T8F81C PLL input from the GPIOL_20 pin in the T8F81C bank
1A / 1B header (J27).

Headers
The board contains a variety of headers to provide power, inputs, and outputs, and
to communicate with external devices or boards.
Table 1: Trion™ 8 BGA81 Development Board Headers
Reference Designator Description
J1 Mini-USB type B socket
J3 22-pin header for T8F81C bank 1A/1B I/O
J4 22-pin header for T8F81C bank 2A I/O
J5 22-pin header for T8F81C bank 2B I/O
J6 6-pin header to select T8F81C VDDIO2A
J8 6-pin header to select T8F81C VDDIO2B
J27 3-pin header to select T8F81C PLL input source
J29 2-pin header to provide USB 5 V for external devices or boards
Header J1
J1, a mini-USB type B socket, is the interface between the board and your
computer for power and communication. Because the USB cable provides power
to the board, the board must be connected to your computer even if the computer
(host) is not actively communicating with the board. To operate, the board expects
to receive 5 V DC (500 mA) on this interface.
Headers J3, J4, and J5
The board headers J3, J4, and J5 contain the Trion™ 8 BGA81 Development Board
GPIO pins. These 2 x 11 (22-pin) headers connect external devices to T8F81C I/O
banks 1A/1B, bank 2A, and bank 2B, respectively.
•J3 links to bank 1A and 1B GPIO pins. VDDIO is fixed at 3.3 V.
•J4 links to bank 2A GPIO pins. Bank 2A VDDIO is selectable, and is brought
out to the header; it is the same as the VDDIO2A supply on the T8F81C
device. Refer to J6 Header on page 9 for the pin you use to select
VCCIO2A power.
•J5 links to bank 2B GPIO pins. VDDIO is selectable, and is brought out to the
header; it is the same as the VDDIO2B supply on the T8F81C device. Refer to
J8 Header on page 9 for the pin you use to select VCCIO2A power.

J27 Header
J27 is a 3-pin header used to select the source for the T8F81C PLL input. The
PLL can receive input from the on-board 33.333 MHz oscillator or a user supplied
clock on pin 20 (GPIOL_20) on J3 (T8F81C bank 1A/1B header).

J29 Header
J29 is a 2-pin header that provides the 5 V input from the USB interface as a power
source for external devices that interface with the development board. Because this
supply is from the USB interface, you are limited to 500 mA of current. However,
the same 5 V also feeds into the on-board regulator that supplies 1.1 V core to the
T8F81C, 3.3 V to the flash device and oscillator, and 3.3 V, 2.5 V, and 1.8 V to
T8F81C VDDIO pins.
Caution: Use caution when driving external peripherals or boards. The
current draw should not exceed the USB limit of 500 mA.
