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 Diamond Programmer (required for re-
programming)
• Optional: ispLEVER Classic 1.4 (ispMACH 4000V CPLD support)
Demonstration Design
Lattice provides a pre-programmed demo to illustrate basic operation of the ispMACH 4256V CPLD device. The
design integrates an up-counter which uses an external 5 MHz SiTIME oscillator. The design alternates to CPLD
outputs, illuminating LEDs D1, D3, D5 and D7 then LEDs D2, D4, D6 and D8.
Note: To restore the factory default demo or program it with other Lattice-supplied examples see the
section of this document.
