Part 3.11: Temperature sensor
A high-precision, low-power, digital temperature sensor chip, model LM75A from ON Semiconductor, is mounted
on the AXP50 development board. The temperature accuracy of the LM75a chip is 0.125 degrees, the sensor and
the FPGA are directly I2C digital interfaces, and the FPGA reads the temperature near the current development
board through the I2C interface. Figure 28 below shows the design of the LM75A sensor chip.
