Package Thermal Characteristics
Table 14 provides the thermal characteristics for the various
Spartan-II FPGA package offerings. This information is also
available using the Thermal Query tool on xilinx.com
The junction-to-case thermal resistance (
θJC) 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 (
θJB)
value similarly reports the difference between the board and
junction temperature. The junction-to-ambient (
θJA) value
reports the temperature difference between the ambient
environment and the junction temperature. The
θJA value is
reported at different air velocities, measured in linear feet
per minute (LFM). The “Still Air (0 LFM)” column shows the
θJA value in a system without a fan. The thermal resistance
drops with increasing air flow.
