Package Thermal Characteristics
The power dissipated by an FPGA application has implications on package selection and system design. The power
consumed by a Spartan-3AN FPGA is reported using either the
integrated in the Xilinx® ISE® development software.
Spartan-3AN FPGA packages. This information is also available using the Thermal Query tool at
http://www.xilinx.com/cgi-bin/thermal/thermal.pl.
The junction-to-case thermal resistance (
body (case) and the junction temperature per watt of power consumption. The junction-to-board (
the difference between the board and junction temperature. The junction-to-ambient (
difference between the ambient environment and the junction temperature. The
velocities, measured in linear feet per minute (LFM). The “Still Air (0 LFM)” column shows the
a fan. The thermal resistance drops with increasing air flow.
