The MachXO Starter Evaluation Board is a complete work-
ing solution for the MachXO crossover programmable logic
technology. Efficiently packed with a rich set of features, the
MachXO Starter Evaluation Board is a simple, yet versatile
solution allowing for detailed analysis of the MachXO perfor-
mance and technology. The board is also a convenient plat-
form to help you get started with your own MachXO design.
Efficient and Flexible Design
The MachXO Starter Evaluation Board is packed with basic
building blocks that can be used to demonstrate any number
of programmable logic features or functions:
I/O Evaluation
Measure the drive strength, speed, and switching character-
istics of the MachXO I/Os, configured to whatever specifica-
tion you program.
Measure Power Consumption
Check the actual power consumption of a MachXO design,
see how changes in your design, and various MachXO set-
tings, affect power results.
In-System Evaluation
Use the prototype area to connect to any number of instru-
ments or see how the MachXO interfaces with other technol-
ogy.
Discover Lattice Technology
The MachXO Starter Evaluation Board, along with down-
loadable software tools, give you everything you need to
evaluate the entire Lattice design flow without making a
huge investment.
MachXO Crossover PLD
The MachXO family of non-volatile, infinitely reconfigurable
Programmable Logic Devices (PLDs) is designed for applica-
tions traditionally implemented using CPLDs or low-capacity
FPGAs.
The MachXO family combines an optimized Look-Up Table
(LUT) fabric with Lattices ispXP technology to provide the
high pin-to-pin performance and instant-on associated with
CPLDs, with the flexibility of FPGAs, all in a single low-cost
device.

Demo Example: Re-programming without
System Interruption
Lattice's Transparent Field Reconfiguration (TransFR) feature
enables the MachXO to be re-programmed without significant
system interruption. This unique capability can be easily demon-
strated with the MachXO Starter Board.
Step 1
MachXO-256
JEDEC
ispDOWNLOAD
Cable
Evaluation
Board
ispVM Software
Program the MachXO device on the Evaluation Board with the
sample program (JEDEC file) using the ispVM System software,
and the ispDOWNLOAD Cable.
Step 2
ispLEVER
Software
JEDEC2
Use the ispLEVER Design Tools to modify the sample program
(e.g. reverse the counter), and generate a second, modified
JEDEC programming file. (JEDEC2)
Step 3
MachXO-256
JEDEC2
Re-program MachXO in <2mS
without system interruption!
ispVM Software
With the ispDOWNLOAD Cable still attached, use the ispVM
System software to perform a TransFR operation to the MachXO
device, programming the Flash Block on the MachXO with the
modified JEDEC file, while the FPGA operates. The new pro-
gram can then be loaded to the SRAM when convenient, for
seamless function changeover.
