Storage and Handling
Static electricity can shorten the lifespan of electronic components. 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 wristband.
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 (installed as an option within the Diamond installation program)
Lattice Diamond® (MachXO support)
ispVM System™ 17.9 or later (Required for re-programming)

MachXO 2280 Device
This board features the LCMXO2280C PLD, which offers the benefits of increased system integration by providing over
27Kbits of embedded memory, two built-in PLLs, high performance LVDS I/O, and a low power sleep mode, all in a
single-device. The 256-pin ftBGA package provides 211 user I/O in a 17 mm × 17 mm package. A complete description
of this device is available in
MachXO Family Data Sheet (DS1002)

Demonstration Design
Lattice provides a pre-programmed demo to illustrate the basic operation of the LCMXO2280C device. The design
integrates an up-counter with the on-chip oscillator.
Note: You may obtain your Breakout Board after it is reprogrammed. To restore the factory default demo and program
it with other Lattice-supplied examples, see the
section of this document.

Running 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 MachXO 2280 on-chip oscillator. The counter module is clocked at ~22 MHz (18 MHz – 26 MHz)
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 200 ms. The resulting light pattern appears as an alternating pair
of lit LEDs per row.
