Evaluation Kit User’s Guide
Introduction
Thank you for choosing the Lattice Semiconductor ispMACH®4256ZE Breakout Board Evaluation Kit!
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 Storage and Handling
section for handling and storage tips.

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.
Note: To restore the factory default demo or program it with other Lattice-supplied examples see the Download
Demo Designs section of this document.

The preprogrammed demonstration design is an up counter and an output multiplexer to drive an LED array. The
demo shows a clock generator based on the ispMACH 4256ZE on-chip oscillator and timer (OSCTIMER) hardware
feature. The counter module is clocked at <5kHz to illustrate the ease at which very low speed timer functions can
be implemented with a CPLD. The 15-bit up counter advances each second. An output mux selects between hexa-
decimal patterns AAh or 55h depending on the count. The resulting light pattern will appear as an alternating pair
of lit LEDs per row.

3. Run ispVM System. Choose ispTools > Install/Uninstall LSC USB/Parallel Port Driver.
The LSC 32/64-Bit USB Drivers Install/Uninstall dialog appears.
4. Select FTDI USB 32-Bit Driver or FTDI USB 64-Bit Driver then click Install.
After a few moments, ispVM will indicate the installation is complete.
5. Click OK, then click Close from the LSC 32/64-Bit USB Drivers Install/Uninstall dialog.
6. Choose File > Exit to close ispVM System.
7. Connect the USB cable from a USB port on your PC to the board’s USB mini-B socket (J2). After connection is
made, a green Power LED (D9) will light indicating the board is powered on.
8. Red LEDs will light and start to flash according to the preprogrammed demonstration design.
See the Troubleshooting section of this guide if the board does not function as expected.

Subsystems
This section describes the principle subsystems for the ispMACH 4256ZE Breakout Board in alphabetical order.
Clock Sources
All clocks for the counter demonstration designs originate from the ispMACH 4256ZE CPLD on-chip oscillator and
timer (OSCTIMER) block. You may use an expansion header landing to drive a CPLD input with an external clock
source.
Expansion Header Landings
The expansion header landings provide access to user GPIOs, primary inputs, clocks, and Bank 0/1 VCCO pins of
the ispMACH 4256ZE. The remaining pins serve as power supplies for external connections. Each landing is con-
figured as one 2x20 100 mil.

Board Modifications
This section describes modifications to the board to change or add functionality.
Bypassing the USB Programming Interface
The USB programming interface circuit (section 6.2.8 USB Programming and Debug Interface) may be optionally
bypassed by removing the 0 ohm resistors: R3, R4, R7, and R9 (See Schematic Sheet 2 of 4, Appendix A. Sche-
matics). Header landing J1 provides JTAG signal access for jumper wires or a 1x8 pin header.
Applying External Power
The Breakout Board is powered by the circuit of Schematic Sheet 2 of 4 based on the 5V USB power source. You
may disconnect this power source by removing the 0 ohm resistors: R47 (VCCO 3.3V, Bank 0), R48 (VCCO 3.3V,
Bank 1), and R53 (VCC 1.8V, Core). Power connections are available from the expansion header landing, J6,
Schematic Sheet 3 of 4.
Measuring Bank and Core Voltages
Test points (TP1, TP2, and TP3) provide access to bank VCCO and VCC core power supplies of the ispMACH
4256ZE CPLD. 0 ohm resistors: R47 (VCCO 3.3V, Bank 0), R48 (VCCO 3.3V, Bank 1), and R53 (VCC 1.8V, Core)
can be removed to add a current meter inline or add a resistor shunt to measure voltage across.
Mechanical Specifications
Dimensions: 3 in. [L] x 3 in. [W] x 1/2 in. [H]
Environmental Requirements
The evaluation board must be stored between -40° C and 100° C. The recommended operating temperature is
between 0° C and 90° C.
The board can be damaged without proper anti-static handling.

Troubleshooting
Use the tips in this section to diagnose problems with the ispMACH 4256ZE Breakout Board.
LEDs Do Not Flash
If power is applied but the board does not flash according to the preprogrammed counter demonstration then it is
likely that the board has been reprogrammed with a new design. Follow the directions in the Demonstration Design
section of this document to restore the factory default.
USB Cable Not Detected
If ispVM System does not recognize the USB cable even after installing the Lattice USB Port Drivers and rebooting,
the incorrect USB driver may have been installed. This usually occurs if you attach the board to your PC prior to
installing the USB driver or ispVM System software.
To access the Troubleshooting the USB Driver Installation Guide:
1. Start ispVM System and choose Options > Cable and I/O Port Setup.
The Cable and I/O Port Setup Dialog appears.
2. Click the Troubleshooting the USB Driver Installation Guide link.
The Troubleshooting the USB Driver Installation Guide document appears in your system’s PDF file reader.
3. Follow the directions of the guide to install the Lattice USB driver.
Determine the Source of a Pre-Programmed Device
You may receive your Breakout Board after it has been reprogrammed by someone else. To restore the board to
the factory default, see the Download Demo Designs section for details on downloading and reprogramming the
device.
You can also determine which demo design is currently programmed onto the Breakout Board by comparing the
JEDEC checksums against of the programming file with what is read from the programmed part.
To compare JEDEC file checksum:
1. Connect the Breakout Board to a host PC using the USB port.
2. Start ispVM and choose ispTools > Scan.
The device appears in the Device List.
3. Double-click the device row.
The Device Information dialog appears.
4. Click the Browse button.
The Save as Data File dialog appears.
5. Specify a new JEDEC Data File name and click the Save button.
6. From the Operation list choose Read and Save JEDEC and click OK.
7. Choose Project > Download.
ispVM reads the contents from the device and writes the results to the JEDEC file specified.
Open the JEDEC file into a text editor and page to the bottom of the file.
Note the hexidecimal checksum at the line above the User Electronic Data note line. Compare this value
against the checksum of the original JEDEC demo programming files.
