• 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. -
Page 4: Run The Demonstration Design
4256V Breakout Board Evaluation Kit The preprogrammed demonstration design is an up counter which is used to drive an LED array. The demo uses the external 5 MHz SiTIME oscillator to run the counter. The 23-bit up counter advances each second. The output of the counter is used to drive the LED array. -

4256V Breakout Board Evaluation Kit To load the FTDI chip USB hardware drivers via the stand-alone package: 1. Browse to www.latticesemi.com/breakoutboards and download the FTDI chip USB Hardware driver package. 2. Extract the FTDI chip USB Hardware driver package to your PC hard drive. - Page 6 USB connector. When the board is connected to a PC with a USB cable, it is recognized by the ispVM System soft- ware as a USB Download Cable. The ispMACH 4256V can then be scanned and programmed using the ispVM System software.
- Page 7 All clocks for the counter demonstration design originates from an external 5 MHz oscillator connected to Pin 128 of ispMACH 4256V chip. You may use an expansion header landing to drive a CPLD input with an alternate clock source. To drive Pin 128 from header J4, disconnect X5 from the circuit by removing R23.
