External Temperature Sensing Diode Specifications

Table 35.  External Temperature Sensing Diode Specifications for Intel® Stratix® 10 Devices
  • The typical value is at 25°C.
  • The temperature diode characteristics in this table target for three-currents temperature sensing chip implementation. The characteristics can also apply to two-currents temperature sensing chip implementation, except for the ideality factor for L-Tile and H-Tile.
  • Absolute accuracy is dependent on third-party external diode ADC and integration specifics.
