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 XPower Power Estimator or the XPower Analyzer calculator
integrated in the Xilinx ISE development software. Table 67 provides the thermal characteristics for the various
Spartan-3AN FPGA packages. This information is also available using the Thermal Query tool at
The junction-to-case thermal resistance (
JC) indicates the difference between the temperature measured on the package
body (case) and the junction temperature per watt of power consumption. The junction-to-board (
JB) value similarly reports
the difference between the board and junction temperature. The junction-to-ambient (
JA) value reports the temperature
difference between the ambient environment and the junction temperature. The
JA value is reported at different air
velocities, measured in linear feet per minute (LFM). The “Still Air (0 LFM)” column shows the
JA value in a system without
a fan. The thermal resistance drops with increasing air flow.
