lists the power measurement ADC component references and
manufacturing information.
Temperature Sense
Temperature monitoring for the Stratix IV GX FPGA die is achieved with a MAX1619
temperature sense device. The MAX1619 device connects to the MAX II CPLD
EPM2210 System Controller and the Stratix IV GX device by a 2-wire SMB interface.
The MAX 1619 device is located at address 0x1. This bus is also routed to a single
voltage and power monitor chip for the 12-V power rail at address 0x2.
The
OVERTEMPn
and
TSENSE_ALERTn
signals are driven by the MAX1619 temperature
sense device based on a programmable threshold temperature. The
OVERTEMPn
signal
is driven to the MAX II EPM2210 System Controller which controls
OVERTEMPn
. The
MAX II EPM2210 System Controller can control fan speed based on a register setting
and can also override the MAX1619 device with the
FAN_FORCE_ON DIP
switch to force
the fan to be on constantly at full speed. For more information on this control, refer to
the MAX II EPM2210 System Controller source code found in the development board
installation directory
