Introduction
Thank you for choosing the Lattice Semiconductor ispMACH
®
4256V Breakout Board Evaluation Kit!
This user guide describes how to start using the ispMACH 4256V Breakout Board, an easy-to-use platform for
evaluating and designing with the ispMACH 4256V CPLD. Along with the board and accessories, this kit includes a
pre-loaded hardware test program. You may also reprogram the on-board ispMACH 4256V device to review your
own custom designs.
Note: Static electricity can severely shorten the lifespan of electronic components. See the
section for handling and storage tips.
