Revision History
1. The Power Calculator tool is based on equations with constants based on a room temperature of 25°C.
2. The user can define the Ambient Temperature (T
3. I/O power consumption is based on output loading of 5pF. Users can change this capacitive loading.
4. The Power Calculator provides an estimate of the power dissipation and current for each of the following
5. The nominal VCC is used by default to calculate power consumption. A lower or higher VCC can be cho-
6. Airflow in Linear Feet per Minute (LFM) can be entered by the user along with the Heat Sink option to cal-
7. The default value of the I/O types is LVCMOS12, 6mA.
8. The Activity Factor (AF) is defined as the toggle rate of the registered output. For example, assuming that
