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 V
DD
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 .
