Part 3.10: Temperature Sensor

A high-precision, low-power, digital temperature sensor chip is mounted on
the AX7A200 FPGA development board, and the model is LM75 of ON
Semiconductor. The temperature accuracy of the LM75 chip is 0.5 degrees,
I2C bus is shared with EEPROM. 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 3-10-1 below
shows the design of the LM75 sensor chip.
