The invention discloses a power-on reset circuit, and an integrated circuit and an EEPROM system. The power-on reset circuit comprises a first MOS transistor, a second MOS transistor, a third MOS transistor, a fourth MOS transistor, a fifth MOS transistor, a first capacitor, a second capacitor and a resistor. According to the power-on reset circuit provided by the invention, the reset threshold level of the power-on reset circuit can be set by setting the resistance of the resistor and the capacitance of the first capacitor to realize the reset circuit with low power consumption and variable reset threshold level. In addition, the power-on reset circuit has the advantages of being small in layout area, low in power consumption and low in cost and so on, and can be integrated in one integrated circuit or integrated in one EEPROM system. 本发明公开了种上电复位电路及集成电路和EEPROM系统，其中上电复位电路包括第MOS管、第二MOS管、第三MOS管、第四MOS管、第五MOS管、第电容器、第二电容器和电阻。本发明提供的上电复位电路，通过设置电阻的阻值和第电容器的电容值，可设置上电复位电路的复位阈值电平，实现低功耗、复位阈值电平可变的复位电路。另外，该上电复位电路具有版图面积小、功耗低
