Spartan-3 FPGA Family: Pinout Descriptions
Package Thermal Characteristics
The power dissipated by an FPGA application has implications on package selection and system design. The power
consumed by a Spartan-3 FPGA is reported using either the XPower Estimator (XPE) or the XPower Analyzer integrated in
the Xilinx ISE development software. Table 86 provides the thermal characteristics for the various Spartan-3 device/package
offerings.
The junction-to-case thermal resistance (θ_JC) indicates the difference between the temperature measured on the package
body (case) and the die junction temperature per watt of power consumption. The junction-to-board (θ_JB) value similarly
reports the difference between the board and junction temperature. The junction-to-ambient (θ_JA) value reports the
temperature difference per watt between the ambient environment and the junction temperature. The θ_JA value is reported
at different air velocities, measured in linear feet per minute (LFM). The “Still Air (0 LFM)” column shows the θ_JA value in a
system without a fan. The thermal resistance drops with increasing air flow.
