Introduction
Thank you for choosing the Lattice Semiconductor MachXO Mini Development Kit!
This user’s guide describes how to start using the MachXO Mini Development Kit, an easy-to-use platform for evaluating and designing with MachXO PLDs. Along with the evaluation board and accessories, this kit includes a preloaded Mini System-on-Chip (SoC) demonstration design based on the LatticeMico8™ microcontroller.
Note: Static electricity can severely shorten the life span of electronic components. See the MachXO Mini Development Kit QuickSTART Guide for handling and storage tips.

devices in the 144-pin TQFP (20x20 mm) package. A complete description of this device can be found in the
MachXO Family Data Sheet.
Note: The connections referenced in this document refer to the LCMXO2280C-4TN144C device. Available I/Os
and associated sysIO™ banks may differ for other densities within this device family. However, only the
LCMXO2280C-4TN144C device offers full functional use of the entire evaluation board.
Demonstration Designs
Lattice provides three demos that illustrate key applications of the MachXO device:
• Mini SoC – Illustrates use of the LatticeMico8 microcontroller, firmware, and peripherals (UART communication,
SPI Flash memory controller, SRAM controller, and I2C peripheral controller). The Mini SoC demo design is preprogrammed into the MachXO Mini Evaluation Board by Lattice.
• MachXO Sleep Mode – Shows application of an external “sleep circuit” to cycle the low-power, sleep mode input
of the MachXO PLD.
• TransFR – Shows the Lattice transparent field reconfiguration (TransFR™) technology with the MachXO.
Note: It is very likely that you will obtain your Mini board after it has been reprogrammed. To restore the factory
default demo or program it with other Lattice-supplied examples see the Download Demo Designs and Programming Demo Designs with ispVM™ sections of this document.
Mini SoC Demo
The Mini SoC demo is pre-programmed into the non-volatile Flash memory of the MachXO PLD and is operational
upon power-up. The design provides the following features:
• Reads the on-board I2C temperature sensor and displays real-time results as a level meter onto the LED bank
(D0-D7).
• Logs temperature measurements into the on-board SRAM or non-volatile SPI Flash memory.

MachXO Sleep Mode Demo
The MachXO sleep mode demo illustrates one possible implementation for power savings. Using this method, the
MachXO device provides supervisory logic to control its own SLEEPN pin. Periodically, the device becomes active
to monitor a trigger event. If the event is not present, it deactivates to save power.
When the SLEEPN pin is asserted (low), the following occur:
• The device powers down internally, dropping power consumption to less than 100µA
• All I/Os are tristated
When the SLEEPN pin is de-asserted (high), power is restored and the MachXO is reconfigured and ready to operate in 1ms or less. Due to the dramatic reduction in power consumption and the fast “instant-on” capability, a
scheme can be implemented with a few simple, inexpensive external components deactivate the device and reactivate with a duty cycle ratio that saves substantial power.

SLEEPN (70)
When I/O pin 89 goes low, C60 discharges. PNP transistor Q5 then conducts, discharging C59. Provided SW1D is
closed, this value is forced onto the SLEEPN pin of the MachXO device, putting it into low power sleep mode.
Once in sleep mode, all I/O pins are tristated, allowing C60 to slowly charge. This then turns off Q5 and allows C59
to charge. Once the amount of charge is sufficient to place a logic high level on SLEEPN, the device returns to normal operating mode.
The MachXO begins operating, as defined by its programmed function. In this demonstration, I/O pin 89 is driven
high initially to allow the device an opportunity to remain active long enough to check whether switch S1 is pressed.
If S1 is not pressed, I/O pin 89 is driven low and the cycle repeats.
If S1 is pressed at that moment, the device remains operational for the entire cycle of an internal counter (~3 sec)
and the LEDs are illuminated during this time. S1 is then checked after each subsequent cycle.
To exit sleep mode or to reprogram the device, open switch SW1D (SW1-4).

Operating the Sleep Mode Demo
To operate the Sleep Mode Demo:
1. To observe the sleep/wake power savings, place voltmeter leads across J2 (VCC CORE) or J3 (VCC AUX).
Each number attaches across a 0.2 ohm resistor between the +3.3V supply rail and VCC_CORE or
VCC_AUX. The average voltage level will drop significantly during the sleep/wake cycle. You may estimate current consumption with Ohm’s Law where I = V / 0.2 ohms.
2. Toggle SW1_1 (A), SW1_2 (B), and SW1_3 (C) to the OFF position. All user LEDs D7-D2 are dim and user
LED D1-D0 are lit. The DIP switch inputs 1-3 are tied directly to the LED bank according to the table below.
SW1
LED
N/A
0, 1 (ON)
_1 (A)
2, 5
_2 (B)
3, 6
_3 (C)
4, 7
3. Adjust DIP switches 1-3 and note the pattern on the LED array.
4. Enable the MachXO Sleep Mode circuit, toggle the SW1D (4) to the ON position. The MachXO enters a
sleep/wake cycle.
According to the parameters of the external Sleep Mode circuit the MachXO will periodically wake to check for
user input and drive the LED bank. If no inputs have changed it will return to the sleep state. The LED bank will
flicker during the sleep/wake cycle.
5. Depress SW1. The MachXO wakes for ~3s and the LED array is lit according the SW1 values. Once the SW1
is released the Mini board reverts to the sleep/wake cycle.
To exit sleep mode or to reprogram the device, open switch SW1D (4).
Note: Pressing push-button SW2 will assert the dedicated MachXO SLEEPN input with any design.
TransFR Demo
This demo illustrates the TransFR (TransparentFieldReconfiguration) feature of the MachXO PLD. The TransFR
solution uniquely allows logic to be updated in the field without interrupting system operation.
The demo first programs the MachXO device with a count-up function, which drives eight LEDs. It then freezes
these outputs while a count-down function is loaded into the device’s SRAM configuration space. The demo then
concludes by releasing the outputs to display the count-down function.
The TransFR feature allows the MachXO to lock its I/Os in a deterministic state while a new configuration is loaded
into the device’s SRAM configuration space. This minimizes system interruption by dynamically configuring the
MachXO with a new pattern without tri-stating its output pins.
The inputs for the incrementing and decrementing design are:
• CLK: Clock to drive the counter and internal logic
• RSTn: Resets counter to 0, asserted low.
• CNTEN: Enables counting when asserted high.
• CAP_EN: Captures the counter value on LEDs when asserted high.
• LOADn: When asserted high, enables the counter values to be displayed on LEDs. When asserted low, this
input tristates the pins that drive the LEDS, and forces a synchronous load of the values captured by the
CAP_EN.
12
MachXO Mini Development Kit
User’s Guide
The CLK connects directly to the oscillator on the board. The RSTn (global reset) is connected to user push-button
(S1) of the Mini board. The other three inputs come from the SW1 DIP switch bank at the right hand side of the Mini
board.
The outputs of the MachXO device are as follows:
• LED_OUT[7:0]: Most significant eight bits of the counter to be displayed through eight LEDs to show the counter
values in binary format.
Download the TransFR Demo Design
To download the TransFR Demo source files, see the Download Demo Designs section of this document.
Programming the Initial Up-Counter Design
To program the up-counter design JEDEC file:
1. Set the control signals with the Mini board SW1 DIP switches as follows:
• LOADn (SW1_1) is set to 1 (OFF)
• CNTEN (SW1_2) is set to 0 (ON)
• Cap_en (SW1_3) is set to 0 (ON)
2. Use ispVM to download the Mini board with the .\Demo_MachXO_Mini_TransFR_Up_Counter\project\up_count.jed file.
See the Programming Demo Designs with ispVM section of this document for details on programming the Mini
board with ispVM.
The up-counter design is first loaded into Flash then immediately into SRAM space. In doing so, the LEDs will
light up, showing the initial value of the counter (all 1s). The SRAM and Flash configuration spaces are now
both programmed with the count-up function.
3. Toggle SW1_2 CNTEN to the OFF (1) position. The LEDs show the up-counter values.
In the following procedure you will load a down-count function into the MachXO Flash program space. After the
TransFR operation is complete, the down-counter results will be displayed on LEDs.
4. Toggle SW1_2 CNTEN to the ON (0) position. Note the up-counter value.
Download the Down-Counter Design to the MachXO Flash Space
To program the down-counter design JEDEC file:
1. From ispVM System, choose ispTools > Scan Chain. The New Scan Configuration Setup window appears.
2. Double-click the LCMXO2280C entry in the Device List. The Device Information dialog appears.
3. From the Data File section click the Browse button. The Open Data File dialog appears.
4. Browse to the .\Demo_MachXO_Mini_TransFR_Down_Counter\project folder, select down_count.jed, and

MachXO Mini Development Kit
User’s Guide
6. From the Operation section, choose: XFLASH Erase, Program, Verify, and click OK.
7. Choose Project > Download. ispVM reprograms the Mini board.
Programming requires about 20 to 40 seconds. A small timer window will appear to show elapsed programming time. At the end of programming, the configuration setup window should show a “PASS” in the “Status”
column.
The down-counter program is now loaded into the Flash configuration space. Since the up-counter function is
still programmed into the SRAM configuration space, the count up function still appears on the LED bank. The
count-down function will be loaded in the SRAM space when the TransFR operation is performed in the next
procedure.
Transfer the MachXO Flash to SRAM Space
At this point in the demo, the down-counter function is loaded into the Flash configuration space, and the up-counter function is loaded into the SRAM space. In this section, an *.svf file is generated and used in the ispVM SVF
debugger tool. The debugger tool steps through the SVF file to lock the I/Os at their current state (via TransFR
technology), load the Flash configuration space into the SRAM space, then release the I/Os. This allows the loading of a new configuration without the I/Os ever having been tri-stated.
To prepare the transfer of Flash configuration contents to the SRAM space of the MachXO:
1. From ispVM System, choose ispTools > Scan Chain. The New Scan Configuration Setup window appears.
2. Double-click the LCMXO2280C entry in the Device List. The Device Information dialog appears.
3. From the Device Access Options section select Flash Background Mode.

6. Click OK.
7. Place the cursor at the top of the file, above the first instruction. This will ensure that you step through all the
instructions in order.
8. Press the Step key F11 (Command > Step). The SVF Debugger advances to the next line of executable code.
9. Step 2-3 more times. Each time you click the STEP button, it executes an instruction, then advances to the next
instruction. Each time you step through an instruction, it is translated, goes through the USB download cable,
and is executed in the MachXO device.
10. Continue to slowly step through the code and stop just before getting to the instruction that reads (about Line
51):
! Shift in ISC ERASE(0x03) instruction
SIR 8
TDI
(03);
Note that LEDs are still counting up. Now step once while watching the displays. Note that the displays have
stopped. The device outputs are now under boundary scan control. A TransFR operation (embedded in the just
executed instruction) has locked the outputs at whatever count values they were at when the TransFR action
occurred.
11. From the Mini board, toggle the SW1_2 CNTEN to the ON (0) position. This will stop the counter from counting
once the device is out of the boundary scan mode.
12. Press F11 until the cursor highlights the BYPASS instruction:
! Shift in BYPASS(0xFF) instruction
SIR
8
TDI (FF);
13. Press F11 once more. The cursor highlights:
RUNTEST IDLE...;
At this point, the new pattern has been loaded into the SRAM memory space and the switch inputs are monitored, but the outputs are still controlled by boundary scan and are still frozen at the same values.
14. Press F11. SVFDebugger reports “Process Done. No Error”. Click OK.
The MachXO I/Os are now released from boundary scan control and counter’s initial value (0xFF) is driven to
the LED displays. The displays do not start counting yet because the CNTEN is deasserted.
15. From the Mini board, toggle the SW1_2 CNTEN to the OFF (1) position. The LED display starts counting down
from the initial value.
The MachXO has exchanged the up-counter for the down-counter function, without disrupting the output PIOs.
Another variation of the demo is to initialize the down-counter with the current state of the up-counter. After step 12
in the procedure, toggle CAP_EN (SW1_3) up and down once (toggle from ‘ON’ (0) to ‘OFF’ (1) and back to ‘ON’
(0)), then toggle LOADn (SW1_1) down and up once (go from ‘OFF’ (1) to ‘ON’ (0) and back to ‘OFF’ (1)). Following step 14, the counter value displayed on the LEDs will not change. Following Step 15, the down-counter will
begin from the value displayed on the LED bank.
Note: See TN1087, Minimizing System Interruption During Configuration Using TransFR Technology for more
information.

Power Supply
A single 3.3V supply voltage for the board components is provided from the USB DEBUG connection.
Push-buttons
The board has two user push-button switches (S1 and S2). S1 connects to the GSRN pin which asserts the Global
Set/Reset input on the MachXO. In order for the GSR to operate, it is necessary to instantiate the GSR macro in
the VHDL/Verilog HDL source, otherwise it may be used as a general input pin. S2 is routed to the SLEEPN pin
which asserts the MachXO Sleep Mode. Both push-buttons are normally pulled high, and when pressed are
asserted to ground.

Troubleshooting
Mini Board is Not Responsive or ispVM Reports Programming Errors
Ensure SW1D (4) is toggled to the OFF position. This will disable the MachXO Sleep Mode circuit.
Determine the Source of a Pre-Programmed Part
It is likely that you will receive your Mini board after it has been reviewed and reprogrammed by someone else. To
restore the Mini board to the factory default, see the Download Demo Designs section of this document for details
on downloading and reprogramming the device.
You can also determine which demo design is currently programmed onto the Mini 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 Mini board to a host PC using both USB DEBUG and PROG ports.

User’s Guide
2. From the Mini board toggle SW1D to the OFF position.
3. Start ispVM and choose ispTools > Scan. The LCMXO2280C appears in the Device List.
4. From the Operation list choose FLASH Calculate Checksum and click OK.
5. Choose Project > Download. ispVM reads the Flash contents from the MachXO and displays a hexadecimal
checksum value in the Status column.
6. Open the original JEDEC file into a text editor and page to the bottom of the file. Note the hexadecimal checksum at the line above the User Electronic Data note line. Compare this value against the checksum reported by
ispVM.
