Temperature Sensor
The board contains a temperature sensor (Analog Devices ADT7301) to monitor the ambient
temperature. It is a band gap temperature sensor with a 13-bit ADC to monitor and digitize the
temperature reading to a resolution of 0.03125°C. The interface between sensor and FPGA is SPI
serial interface. Detailed information for using the sensor is available in its datasheet, which can be
found on the manufacturer’s website, or in the Datasheets\TEMP_Sensor folder on the SoCKit
System CD.
Figure 3-21
shows the connections between temperature sensor and Cyclone V SoC
FPGA.
Table 3-20
gives the all the pin assignments of the sensor.
