To determine the heat sink's thermal performance, use the following equation:
EQ 2-14
where:
EQ 2-15
A heat sink with a thermal resistance of 9.76°C/W or better should be used. Thermal resistance of heat sinks is a
function of airflow. The heat sink performance can be significantly improved with the presence of airflow.
Carefully estimating thermal resistance is important in the long-term reliability of an Actel FPGA. Design engineers
should always correlate the power consumption of the device with the maximum allowable power dissipation of the
package selected for that device, using the provided thermal resistance data.
Note: The values may vary depending on the application.
