Part 13: Temperature Sensor

A high-precision, low-power, digital temperature sensor chip is mounted on
the AXKU040 FPGA development board, and the model is LM75 of ON
Semiconductor. The temperature accuracy of the LM75 chip is 0.5 degrees.
The sensor and FPGA are directly connected to the I2C digital interface. The
FPGA reads the temperature near the current FPGA development board
through the I2C interface. Figure 13-1 below shows the design of the LM75
sensor chip.
