4 Hardware
4.1 Overview
Figure 1: GreenPAK Advanced Development Board, Top View
Note: all test points were designed only for observation of signals on the pins. Please do not
try to connect external power/signal source to test points, this will affect GreenPAK Advanced
Development Board functionality and may even damage it.
4.2 Functional Description
4.2.1 Power Supply
The main power source of the GreenPAK Advanced Development Board is the USB power line. The
Development Board can deliver power from 0 to 5.5 V. To provide this power range, the
Development Board is equipped with a boost converter. A Signal generator with a buffered output
controls the GreenPAK chip power rail. For more information about GreenPAK electrical
specification, please refer to the datasheet.

4.2.2 USB Communication
The board has the USB communications interface that uses the USB mini-B connector, as shown in
Figure 2. This interface provides communication with the software control tool and supplies power to
the platform, as discussed in 4.2.1.
Figure 2: USB Interface
4.2.3 GND Connections
There are 6 GND pins on the left side, 6 pins and 1 header on the right side. These can be used for
test equipment (oscilloscope, multimeter, and others) ground reference connection or to connect
external test circuitry ground.
4.2.4 Pin Test Points
Each GreenPAK chip pin including VDD has its own observation test point. These test points were
designed only for observation. To connect an external signal source use a software-controlled
expansion connector.
4.2.5 LEDs
All the pins except Pin 2 can be connected to buffered LEDs. This option allows visualization of
digital levels on chip pins. There are 2 selection modes:
▪Buffered LED (with high impedance input)
▪Inverted Buffered LED (with high impedance input)
This option can be enabled in GreenPAK Designer.
4.2.6 Socket Connector
The GreenPAK Advanced Development Board should be used with a detachable socket board. Its
main purpose is to connect the GreenPAK chip to the Development Board. It‘s easy to use the
programmed chip in external circuits, or to measure current consumption of the project.
4.2.7 Expansion Connector
This port was designed to connect the GreenPAK Advanced Development Board to external circuits
and apply external power, signal sources and loads. It can be used to apply the GreenPAK chip into
your custom design with minimal additional tools. For schematic diagram refer to Figure 3.

Figure 3: GreenPAK Expansion Connector Schematic
Each pin except Pin 11 (GND) is controlled through an individual analog switch. Expansion connector
is a standard 0.1” double row connector. GreenPAK Designer can enable or disable external pins, as
it is shown in the Figure 4. The main purpose of the Expansion connector is to connect an external
signal/power source safely to the GreenPAK Advanced Development Board.
Figure 4: Expansion Connector Control in GreenPAK Designer
Figure 5 demonstrates the schematic diagram of the expansion connector control.

Figure 5: Socket and Expansion Connector Schematic
Expansion connector is enabled only in Emulation mode or Test mode. To enter either of these two
modes the GreenPAK chip must be in the socket. When the Test mode button is pressed the
software will first read the chip to verify if it was inserted and then configure the GreenPAK Advanced
Development Board as set in Emulation Tool window. When the Test mode button is gray then the
Development Platform is in Default state and all expansion port switches are open (disconnected).
After Emulation button is pressed, the software will automatically perform the following steps:
▪check chip presence
▪open all expansion port switches (external signals/loads can be left connected to expansion port)
▪use internal power and load configuration to the chip
▪only for case #3: adjust internal power source to external power level → close external power
switch → open internal power switch
▪configure Development Board as set in Emulation Tool window
Parasitic effects should be also considered while using the GreenPAK Advanced Development Board
in-circuit with analog signals. The entire Development Board circuitry along with the wiring have a
significant amount of mutual capacitance and inductance. The detachable socket can also be used
for the in-circuit development with programmed chips (the Development Board and socket
connectors have the same pinout).
The GreenPAK Advanced Development Board provides three possible ways of using expansion
connector:
1) Internal power is used to run the chip, no external power output is needed, external signal
sources and loads can be connected between pins and GND.

The configuration steps:
▪close internal and open external power switch
▪close all used expansion port switches in the software
▪hit Emulation/Test mode button
This is the common way of using an Expansion connector.
Figure 6: Internal Power Source
2) Internal power is used to run the chip and external circuit (internal power source/sink current is
limited to 50 mA).
The configuration steps:
▪close internal power switch
▪close external power switch
▪close all used expansion port switches in the software
▪hit Emulation/Test mode button
Figure 7: Internal Power Source for GreenPAK Chip and External Development Platform
3) External power is used to run the chip and external circuit (internal source output is in Hi-Z state).
The configuration steps:
▪open internal power switch
▪close external power switch
▪close all used expansion port switches in the software
▪hit Emulation/Test mode button (External power should be applied before this step)
Note that the GreenPAK chip has internal OTP memory which is normally loaded into RAM registers
at initialization time.“Emulation mode” will bypass this load, and write the updated version of the
project directly into the RAM register inside the GreenPAK chip many times, but after power loss all
internal data will be lost. When the GreenPAK chip is already programmed the user can use
Emulation mode to load another project and test it on the emulation tool in Emulation mode, in that
case emulation data will be cleared. The “Emulation” mode is not necessary for checking
programmed parts: in this case the “Test mode” is used.
Expansion connector can be divided by types of connections:
1. VDD
2. GND
3. Data connections
The VDD connection enables the user to connect/disconnect external and internal power source. This
connection meets next requirements:
▪External power range: 1.8 - 5.5 V
▪High resistance voltage dividers are not recommended

The GND connection is connected directly to the Development Board, and cannot be controlled by
GreenPAK Designer.
Data connections are the easiest way to connect external lines to the GreenPAK chip. They are
software controlled switches. Every line is connected with a 100 W resistor.

4.2.8 Pins Connectivity
The GreenPAK Advanced Development Board supports connecting eight types of loads and signal
sources. Each source has its own special purpose. The List of available connections for each test
point is presented in Table 1.
