Part 3.14: EEPROM and Temperature sensor
The AXU3EG Fpga development board has an EEPROM onboard. The
model of the EEPROM is 24LC04, and the capacity is: 4Kbit (2 * 256 * 8bit),
which is connected to the PS terminal through the IIC bus.
A high-precision, low-power, digital temperature sensor chip is installed on
the AXU3EG FPGA development board, and the model is LM75 from ON
Semiconductor. The temperature accuracy of the LM75 chip is 0.5 degrees.
The EEPROM and temperature sensor are mounted on the Bank500 MIO
of ZYNQ Ult through the I2C bus. Figure 3-14-1 is the schematic
diagram of EEPROM and temperature sensor
