Storage and Handling
Static electricity can shorten the lifespan of electronic components. Please 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 wrist-band.
• 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 USB Hardware Drivers (www.latticesemi.com/breakoutboards) or ispVM System 17.9 (required for re-pro-
gramming)
• Optional: ispLEVER Classic 1.4 (ispMACH 4000ZE CPLD support)
Demonstration Design
Lattice provides a pre-programmed demo to illustrate basic operation of the ispMACH 4256ZE CPLD device. The
design integrates an up-counter with the on-chip oscillator and timer (OSCTIMER) hardware feature. The design
alternates to CPLD outputs, illuminating LEDs D1, D3, D5 and D7 then LEDs D2, D4, D6 and D8.
