ispMACH 4000ZE Device
This board features the ispMACH 4000ZE CPLD which is ideal for ultra low-power, high-volume portable applications. The on-board LC4256ZE is the highest capacity of the family with 256 macrocells. The 144-pin csBGA package provides 108 user I/Os and four dedicated inputs in a 7mm x 7mm package. The LC4256ZE consumes
standby current as low as 15µA. A complete description of this device can be found in the ispMACH 4000ZE Family
Data Sheet.
Demonstration Designs
Lattice provides two demos that illustrate key applications of the ispMACH 4000ZE CPLD device in the context of a
consumer electronics application:
• Pico Power – Integrates an up/down counter, a right/left shift register, voltage/current meter display, and an I2C
bus master controller that communicates with the on-board POWR6AT6 Power Manager II device. The
POWR6AT6 provides analog power supply monitoring and a 2-wire I2C interface to measure various voltage supplies of the board. An LCD panel displays demo output using three characters. You can select demo features
with the keyboard-style 4-bit DIP switch bank. The Pico Power demo is designed for battery operation but if one
isn’t available you can power the board by connecting the USB cable provided to a PC USB port.
• GPIO I2C Expansion – Shows an application of the LC4256ZE device as an I2C slave processing instructions
issued by a CPU/MPU. CPLDs are ideal GPIO “expanders” for processors. Control registers of the CPLD’s I2C
module allow the processor to access counter and shift registers, I/O, and power measurements. An I2C software
interface utility, PicoView, emulates the CPU/MPU component of the system. Visit www.latticesemi.com/4000zepico-kit to download PicoView.
Note: It is possible that you will obtain your Pico board after it has been reprogrammed. To restore the factory
default demo and program it with other Lattice-supplied examples, see the Download Demo Designs section of this
document.
Pico Power Demo
The Pico Power design highlights low-power features of the LC4256ZE CPLD along with inexpensive PCB design
techniques that help extend battery life, such as low-speed CPLD clocking, efficient use of the CPLD I/O cell’s I/O
bus maintenance feature, and gated supply rails. The demo design integrates an I2C master reference design
(www.latticesemi.com/products/intellectualproperty) with LCD controller logic, an up/down counter and left/right
shift register modules. You may switch the LCD display between a current/voltage meter and counter/shifter operation using the DIP switch bank. The demo shows a clock generator based on the LC4256ZE on-chip oscillator and
timer (OSCTIMER) hardware feature. The counter and shift register modules can be clocked at either <2 Hz or 5
MHz to help illustrate the difference in dynamic power demands.
Current and voltage monitoring of the Pico board is provided by the POWR6AT6 mixed-signal PLD and on-board
sensor circuits (see AN6049, High-side Current Sensing Techniques for Power Manager Devices). To minimize
power consumption of the overall system, the POWR6AT6 supply rail is powered on momentarily by the LC4256ZE
whenever a current or voltage display is requested or after the Pico board is reset.

Pico Power Demo Features
0000 (Up)
0001 (Down)
Decimal Up/Down Counter Display – Displays an 8-bit decimal up/down counter (0.0-9.9) using
the <2 Hz clock generated by the LC4256ZE On-Chip Oscillator and Timer (OSCTIMER). A 4-bit
nibble is committed to the “ones” and “tenths” position of the LCD. The down counter will be initialized to 9.9 and up counter to 0.0 upon power-up, reset or if the count rolls over.
Slow clock <2 Hz:
1100 (VMON1 Icccore)
1001 (VMON2 Iccio)
Current Meter Display – Displays current measurements of the LC4256ZE 1.8V core and 2.5V
I/O supply rails. To help illustrate the relative dynamic power requirements of the board at <2 Hz or
5 MHz, Icccore can be measured at both clock frequencies.
Fast Clock 5 MHz:
1000 (VMON1 Icccore)
The current meter circuit includes a high-side current sensor amp and the POWR6AT6 mixed-signal PLD which provides the voltage monitor, analog-to-digital conversion (ADC), and an I2C slave
to register the measurement. The entire circuit is dynamically energized whenever the current
meter function is selected or the Pico board push-button is pressed. Note that the additional draw
of the meter circuit is factored into the display latched into the LCD panel by the CPLD. This will
result in an additional 100-600 microamp over static measurements taken on the board at the
Icccore and Iccio shunts R35 and R34.
0010 (Shift Left)
0011 (Shift Right)
Left/Right Shift Register Display – Displays a shift register operating as serial-in, parallel-out
using the <2 Hz clock source. Each bit of the register is associated with the corresponding segment of the 7-segment LCD such that reg(21) = Segment 7 of the left-most character and reg(0) =
Segment 1 of the right-most character.
When shifting left, the register will shift in ‘0’ to the MSB upon each clock. When shifting right the
register shifts in ‘0’ to the LSB. The shift register will be initialized to 1FFFFEh upon power-up,
reset, or if the shift result rolls over.
1010 (VMON5 5V USB)
Volt Meter – Displays voltage measurements of the 5V USB interface or the 3V button-cell battery.
1011 (VMON6 3V Battery) The volt meter function dynamically activates the POWR6AT6 supply rail in the same manner as
the Current Meter Display function.
1111 (Standby)
Standby Mode (Default) – Demonstrates standby power of the LC4256ZE. No LCD output is
available in this mode.
In battery-powered, standby mode CPLD core current draw is ~10µA.

Reserved switch settings. No LCD output.
Pico Power Demo Feature
Manual Reset is a push-button switch (SW1) used to assert a manual reset of the demo. All
design modules including the CPLD OSCTIMER will be initialized when SW1 is pressed.
Run the Pico Power Demo
Follow the procedure below to explore the Pico Power demonstration on the evaluation board.
1. Select Switch Bank pattern 1111 (Standby)
The Pico board activates the LC4256ZE standby mode. To measure the current draw of the CPLD core
(Icccore), touch voltmeter leads across R35, read the voltage drop, and then divide by 50 Ohms (I=V/R). The
LC4256ZE draws approximately 10µA in Standby mode. Given a new button-cell battery the Pico board should
be operational for approximately one year in standby mode. As a further measure to minimize CPLD current
draw, I/O Bus Maintenance features are disabled and the DIP switch input is designed to pull input high rather
than open, high-Z. This will avoid current leakage by the CPLD buffers by disabling the internal pull-down resistor circuits.
2. Select Switch Bank pattern 1100 (Low-speed CPLD core current meter)
The LCD displays CPLD core current (Icccore) in microamp (µA) units. The CPLD control logic performs the
following operations to arrive at the result. First, the counter and the shift register modules of the CPLD are
enabled by the internal slow clock (<2Hz) and the ispPAC-POWR6AT6 power supply rail is enabled. Next, the
I2C master module issues three I2C bus cycles to initiate and read the analog-to-digital conversion result of the
POWR6AT6 voltage monitor input (VMON1). Finally, the data is displayed on the LCD in microamp units. The
POWR6AT6 VMON1 is driven by a high-side current sense circuit connected to the CPLD Vcccore supply rail.
Power consumption of the CPLD in the slow speed operation is in the µA range. Note that a volt meter reading
across R35 will reflect current draw after the POWR6AT6 has powered off and therefore be 100-600 microamps less than the value latched by the CPLD.

3. Select Switch bank pattern 0000 (decimal up counter).
The LCD displays a decimal up-counter. The counter uses a divided OSCTIMER clock source set for 5 kHz
nominal (TIMER_DIV=1024). 5 kHz is further divided to produce a count frequency of < 2 Hz. Use the voltmeter technique in step 1 to measure core current.
4. Select Switch bank pattern 1000 (CPLD core current meter).
The LCD displays the VMON1 Icccore in µA units as the CPLD OSCTIMER clocks the counter and shift register design modules at 5 MHz and the LCD at < 2 Hz. At this higher frequency the core current increases.
5. Select Switch bank pattern 0010 (left shift).
The LCD displays the 21-bit shift register module operating on each segment at < 2 Hz.
6. Experiment with other functions and measurements of the Pico Power Demo. 
If the Pico board battery is missing you may connect the Pico board to a USB socket with the cable provided to
enable the USB 5V supply rail.
I2C GPIO Expansion Demo
This demo illustrates I2C traffic between a PC host running the I2C Hardware Verification Utility program (PicoView)
and the Pico board. Data is available at the expansion header landing or LCD display. Control and status registers
of the I2C master and slave modules can be read or written via the PicoView user interface. These instructions
highlight the LC4256ZE, providing general-purpose I/O for an I/O-constrained microprocessor.

Run the I2C GPIO Expansion Demo
These instructions highlight the LC4256ZE providing general-purpose I/O for an I/O-constrained microprocessor or
DSP. A host PC running the Lattice PicoView program emulates a processor reading and writing I2C traffic to I2C
slaves embedded in the LC4256ZE and POWR6AT6 devices. The CPLD integrates Verilog-based I2C slave and
LCD Controller reference designs to translate the traffic to parallel interfaces of the Pico board. The I2C interface to
the POWR6AT6 allows you to monitor voltage or current of various Pico board power supplies.
1. If not already connected, follow the earlier procedures to connect the Pico board and reprogram it. The USB
cable must be attached and powered to enable the Pico board I2C channel and JTAG programming interface.
2. Start a command prompt and run the PicoView program (c:\4000ze-pico-kit\picoview.exe).
PicoView provides a push-button interface to provide read or read/write access to the registers of the
LC4256ZE and POWR6AT6 devices. When PicoView initializes, all device registers are read and the dialog is

Hardware Evaluation
How to evaluate hardware features of the on-board LC4256ZE.
Power Consumption
Tables 1 and 2 list a series of measurements for the CPLD I/O and core current running the Pico Power demonstration design when powered by battery or the USB cable interface.
CPLD power consumption can be measured by the on-board sensor circuits or by metering across resistors R34
(I/O, 100 ohm) and R35 (Core, 50 ohm) of the Pico board (see Figure 2). Use Ohm’s Law to calculate current from
the voltage drop across each resistor: I = V / R.
Note that voltmeter measurements reflect a lower static current level than what the on-board meter and PicoView
results display which accounts for the additional current that occurs when the POWR6AT6, current sense amplifiers, and switch circuits are dynamically powered for a measurement.
The board will draw additional current when USB power is applied due to the LC4256ZE JTAG and I/O pins being
biased from surrounding USB support circuits. When powered by the battery cell, the LC4256ZE pins are isolated
by high-impedance circuits to minimize current leakage paths.

Troubleshooting
No Current/Voltage Meter Readings Available
A low battery can cause the current/voltage meter features of the Pico Power demo to read 0µA/0V. The demo’s
counter and shift register features may operate but the additional current required to energize the current sensor
and POWR6AT6 may not be available once the battery begins to discharge. Install a new battery if this condition
occurs.
Determine the Source of a Pre-Programmed Part
It is possible that you may receive your Pico board after it has been reprogrammed by someone else. To restore the
board to the factory default, see the Download Demo Designs for details on downloading and reprogramming the
device.
You can also determine which demo design is currently programmed onto the Pico 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 Pico board to a host PC using the USB port.
2. Start ispVM and choose ispTools > Scan. The POWR605 and POWR6AT6 devices appear 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.
