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 evalu­ating and designing with the MachXO2280 PLD. Along with the board and accessories, this kit includes a pre­loaded 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.

• 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

•

• 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 inte­grates 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 alternat­ing pair of lit LEDs per row.

Programming with ispVM

A demonstration design is pre-programmed into the Breakout Board by Lattice. To restore a Breakout Board to fac­tory 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 Sys­tem 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.
