MachXO2280 Breakout Board Evaluation Kit
Introduction
Thank you for choosing the Lattice Semiconductor MachXO™2280 Breakout Board Evaluation Kit!
This user guide describes how to start using the MachXO2280 Breakout Board, an easy-to-use platform for evalu-
ating and designing with the MachXO2280 PLD. Along with the board and accessories, this kit includes a pre-
loaded demonstration design. You may also reprogram the on-board MachXO2280 device to review your own cus-
tom designs.
Note: Static electricity can severely shorten the lifespan of electronic components. See the
Storage and Handling
section of this document for handling and storage tips.
Features

nents and circuits:
– MachXO2280 PLD (LCMXO2280C-3FTN256C)
– USB mini-B connector for power and programming
– Eight LEDs
– 40-hole prototype area
– Eight 2x20 expansion header landings for general I/O, JTAG, and external power
– 1x8 expansion header landing for JTAG
– 3.3V supply rail
•
Pre-loaded Demo
– The kit includes a pre-loaded counter design that highlights use of the embedded
MachXO2280 oscillator and programmable I/Os configured for LED drive.
•
USB Connector Cable

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.
