Lattice Semiconductor
The Start Project window is used to create a new Power Calculator Project (*.pep project). Three pieces of data are
entered into the Start Project window.
Power Calculator Main Window
The Power Calculator main window is shown in Figure 4.
Figure 12-4. Power Calculator Main Window (Type View)
The top pane of the window shows information about the device family, device and the part number as it appears in
the Project Navigator. The VCC used for the power calculation is also listed. Users have the choice of selecting the
core voltage VCC with +5% of the nominal value (or values). The option of selecting VCCJ is also available. Users
can provide the ambient temperature, and the junction temperature is calculated based on that.
Users can also enter values for airflow in Linear Feet per Minute (LFM) along with heat sink to obtain the junction
temperature.
The table near the top of the Power Calculator main window summarizes the currents and power consumption
associated with each type of power supply for the device. This also takes into consideration the I/O power supplies.
