Storage and Handling
Static electricity can shorten the lifespan of electronic components. Please observe these tips to prevent damage
that could occur from electro-static discharge:
• Use anti-static precautions such as operating on an anti-static mat and wearing an anti-static wrist-band.
• Store the evaluation board in the packaging provided.
• Touch a metal USB housing to equalize voltage potential between you and the board.
Software Requirements
You should install the following software before you begin developing new designs for the Breakout board:
• FTDI Chip USB Hardware Drivers
•Lattice Diamond™ (MachXO support)
• ispVM System™ 17.9 or later (Required for re-programming)
MachXO2280 Device
This board features the MachXO2280 PLD which offers the benefits of increased system integration by providing
over 27Kbits of embedded memory, two built-in PLLs, high performance LVDS I/Os, and a low power sleep mode,
all in a single-device. The 256-pin ftBGA package provides 211 user I/Os in a 17mm x 17mm package. A complete
description of this device can be found in DS1002, MachXO Family Data Sheet.

Demonstration Design
Lattice provides a pre-programmed demo to illustrate basic operation of the MachXO2280 device. The design inte-
grates an up-counter with the on-chip oscillator.
Note: You may obtain your Breakout Board after it has been reprogrammed. To restore the factory default demo
and program it with other Lattice-supplied examples see the Download Demo Designs section of this document.
Run the Demonstration Design
The preprogrammed demonstration design is an up-counter to drive an LED array. The program shows a clock
generator based on the MachXO2280 on-chip oscillator. The counter module is clocked at ~22 MHz (18-26MHz) to
illustrate how low speed timer functions can be implemented with a PLD. The 23-bit up-counter further divides the
clock to advance the LED display approximately every 200ms. The resulting light pattern will appear as an alternat-
ing pair of lit LEDs per row.

WARNING: Do not connect the Breakout Board to your PC before you follow the driver installation procedure of
this section.
Communication with the Breakout Board with a PC via the USB connection cable will require the FTDI chip USB
hardware drivers contained in the Software Requirements section. Loading these drivers enables the computer to
reliably recognize and program the Breakout Board. Drivers are distributed by Lattice as a stand-alone package or
with ispVM System version 17.9 or later. Use one of the two procedures below to install.
To load the FTDI chip USB hardware drivers via ispVM System:
1. Browse to www.latticesemi.com/breakoutboards and download ispVM System software.
2. Install ispVM System software.
3. Run ispVM System. Choose ispTools > Install/Uninstall LSC USB/Parallel Port Driver.
The LSC 32/64-Bit USB Drivers Install/Uninstall dialog appears.
4. Select FTDI USB 32-Bit Driver or FTDI USB 64-Bit Driver then click Install.
After a few moments, ispVM will indicate the installation is complete.
5. Click OK, then click Close from the LSC 32/64-Bit USB Drivers Install/Uninstall dialog.
6. Choose File > Exit to close ispVM System.
7. Connect the USB cable from a USB port on your PC to the board’s USB mini-B socket (J2). After connection is
made, a green Power LED (D9) will light indicating the board is powered on.
8. Red LEDs will light and start to flash according to the preprogrammed demonstration design.
See the Troubleshooting section of this guide if the board does not function as expected.

MachXO2280 Breakout Board Evaluation Kit
To load the FTDI chip USB hardware drivers via the stand-alone package:
1. Browse to www.latticesemi.com/breakoutboards and download the FTDI chip USB Hardware driver package.
2. Extract the FTDI chip USB Hardware driver package to your PC hard drive.
3. Connect the USB cable from a USB port on your PC to the board’s USB mini-B socket (J2). After connection is
made, a green Power LED (D9) will light indicating the board is powered on.
4. If you are prompted, “Windows may connect to Windows Update” select No, not this time from available
options and click Next to proceed with the installation. Choose the Install from specific location (Advanced)
option and click Next.
5. Search for the best driver in these locations and click the Browse button to browse to the Windows driver folder
created in the Download Windows USB Hardware Drivers section. Select the CDM 2.04.06 WHQL Certified
folder and click OK.
6. Click Next. A screen will display as Windows copies the required driver files. Windows will display a message
indicating that the installation was successful.
7. Click Finish to install the USB driver.
8. Red LEDs will light and start to flash according to the preprogrammed demonstration design.
See the Troubleshooting section of this guide if the board does not function as expected.
Download Demo Designs
The counter demo is preprogrammed into the Breakout Board, however over time it is likely your board will be mod-
ified. Lattice distributes source and programming files for demonstration designs compatible with the Breakout
Board.
To download demo designs:
1. Browse to the Lattice Breakout Board Evaluation Kits web page (www.latticesemi.com/breakoutboards) of the
Lattice web site. Select MachXO Breakout Board Demo Source and save the file.
2. Extract the contents of MachXO2280_BB_Eval_Kit_v01.0.zip to an accessible location on your hard drive.
The demo design directory Demo_LED is unpacked.
Recompile a Demonstration Project with Lattice Diamond
Use the procedure described below to recompile a demo project for the Breakout Board.
1. Install and license Lattice Diamond software.
2. Download the demo source files from the Lattice Breakout Board Evaluation Kits web page.
3. Run Lattice Diamond.
4. Open the Demo_LED_OSC.ldf project file.
5. From the Process view, select JEDEC File from the Export Files process.
6. Choose Export Files, right-click and choose Run.
After a few moments the JEDEC programming file is output.

Programming with ispVM
A demonstration design is pre-programmed into the Breakout Board by Lattice. To restore a Breakout Board to fac-
tory settings or load an alternative demo design, use the procedures in this section.
To install ispVM programming tools:
1. Install and license ispVM System software.
2. Connect the board to a host PC using the USB port header connection.
3. Follow the USB Cable Interface procedure below to program the evaluation board.
The Breakout Board is equipped with a built-in USB-based programming circuit. This consists of a USB PHY and a
USB connector. When the board is connected to a PC with a USB cable, it is recognized by the ispVM System soft-
ware as a USB Download Cable. The MachXO2280 can then be scanned and programmed using the ispVM Sys-
tem software.
To program a demo programming file:
1. From the Start menu run ispVM System.
ispVM appears.
2. Choose Options > Cable and IO Port Setup…
The Cable and I/O Port Setup dialog appears.
3. Make the following selections:
Cable Type: USB2
Port Setting: FTUSB-0
Click OK.
4. Choose ispTools > Scan Chain.
The New Scan Configuration Setup window appears. The LCMXO2280C device appears in the device list.
5. Right-click the LCMXO2280C entry and choose Edit Device…
The Device Information dialog appears.
6. From the Data File section, click the Browse button.
The Open Data File dialog appears.
7. Browse to the <Demo Dir> folder, select <Demo>.jed, and click Open. From the Operation list choose Erase,
Program, Verify and click OK.
8. Choose Project > Download.
ispVM reprograms the evaluation board.
Programming requires about 10 seconds. A small timer window will appear to show elapsed programming time. At
the end of programming, the configuration setup window should show a PASS in the Status column.

Subsystems
This section describes the principle sub systems for the Breakout Board in alphabetical order.
Clock Sources
All clocks for the counter demonstration designs originate from the MachXO2280 PLD on-chip oscillator. You may
use an expansion header landing to drive a PLD input with an external clock source.
Expansion Header Landings
The expansion header landings provide access to user GPIOs, primary inputs, clocks, and VCCO pins of the
MachXO2280. The remaining pins serve as power supplies for external connections. Each landing is configured as
one 2x20 100 mil.

JTAG Interface Circuits
For power and programming an FTDI USB UART/FIFO IC converter provides a communication interface between a
PC host and the JTAG programming chain of the Breakout Board. The USB 5V supply is also used as a source for
the 3.3V supply rail. A USB mini-B socket is provided for the USB connector cable.
