Temperature Sense
Temperature monitoring for the Stratix V GS die is achieved with a MAX1619
temperature sense device. The MAX1619 device connects to the MAX V CPLD
EPM2210 System Controller and the Stratix V GS device by a 2-wire SMB interface.
The MAX1619 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 V System Controller, which controls the OVERTEMPn signal. The
MAX V System Controller can control fan speed is based on a register setting and can
also override the MAX1619 device. For more information on this control, refer to the
MAX V System Controller source code found in the development board installation
directory \kits\stratixVGS_5sgsmd5kf40_dsp\examples\max5.

DSP Development Kit, Stratix V Edition User Guide .
The remote sense routes to the FPGA diode pins to measure the voltage drop. For
very accurate temperature readings, the I/O adjacent to the FPGA diode sense pins
must be halted.
