Introduction
Thank you for choosing the Lattice Semiconductor ispMACH
This user's guide describes how to start using the ispMACH 4256ZE Breakout Board, an easy-to-use platform for
evaluating and designing with the ispMACH 4256ZE CPLD. Along with the board and accessories, this kit includes
a pre-loaded hardware test program. You may also reprogram the on-board ispMACH 4256ZE 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.
