MachXO Standard Evaluation Board
Lattice Semiconductor
Revisions 001 & 002 User’s Guide
The evaluation board also includes a Lattice ispClock5610. This part is also programmed using the same JTAG
interface. The ispClock5610 can be used to generate synthesized clock inputs to the MachXO device.
The evaluation board includes additional components to aid in evaluating the MachXO PLD. These are described in
the following sections in more detail.
Additional Resources
Additional resources related to this board can be downloaded from the web at www.latticesemi.com/boards. Click
on the appropriate evaluation board, then see the blue “Resources” box on the right of the screen for items such as:
updated documentation, downloadable software, sample designs and more.
Getting Started
In order to use the MachXO Standard Evaluation Board, it must first be powered. Follow the guidelines in the
Power Supply section below for details.
The MachXO Standard Evaluation Board is shipped from the factory pre-configured with a sample program loaded
in both the MachXO and ispClock devices. The source code and programming files are available for download from
the Lattice web site at: www.latticesemi.com/boards. The sample programs operate as follows.
MachXO: Setting all of the 8-bit input switches to ON causes the associated LEDs to count in one direction (8-bit
binary counter). Setting all of the 8-bit input switches to OFF reverses the direction of the count. If the switches are
not all ON or all OFF, the LEDs for the switches that are ON will light up. Additionally, other I/Os on the MachXO
device are also toggled using the internal counter outputs. See the source code and preference file available on-
line for more information.
ispClock5610: The ispClock5610 sample program generates a 33MHz clock input to the MachXO device.
To reprogram the board, you will need the following items:
•
ispLEVER Software:
HDL design support for the MachXO device is included in both ispLEVER 5.0 SP1 and
downloadable ispLEVER-Starter 5.0 SP1 (or later) software tools
•
ispVM System:
This is the Lattice programming management tool which is used to download custom ispLEVER
designs from your PC to the MachXO device via an ispDOWNLOAD
®
cable. The ispVM System software is avail-
able for download from the Lattice web site at: www.latticesemi.com/ispvm.
•
ispDOWNLOAD Cable:
An ispDOWNLOAD Cable is required to connect your PC to the MachXO Standard
Evaluation Board. ispDOWNLOAD Cables are available for purchase separately from the Lattice on-line store
(www.latticesemi.com/store) or any Lattice distributor. For more information see:

MachXO Standard Evaluation Board Functional Description
The MachXO Standard Evaluation Board is comprised of several primary functional blocks as shown in Figure 1. In
the descriptions below, locations of components and board features are described relative to a compass symbol
placed adjacent to the Lattice Semiconductor logo. For example, the DIP oscillator is on the southwest corner of
the board, and the Lattice logo is on the northeast corner of the board.
