Temperature Sensor
Temperature
Sensor The board has a two-wire SMBus interface to a MAX1619 temperature
sensing device. This is a low-bandwidth A/D converter that measures
small voltage changes across a 2N3904-equivalent diode on the FPGA’s
die. The device can be programmed to automatically turn on a cooling fan
at a temperature threshold. A regular I/O pin is used to override the fan
control regardless of the MAX1619 device setting.
Heat Sink and
Fan One of several available fans that fits the 55 mm-spaced holes is the
Dynatron SCP1 heat-sink with an integrated fan, which is used for FPGA
heat dissipation on each Stratix II GX device. The fan uses 190 mA at 12 V
and can dissipate 25 W of heat with no additional air flow in a lab-bench
type environment. The 12 V is delivered through a two-pin, 100-mil
header (power and GND).
