Common reset circuit Principle of single-chip reset circuit

The reset circuit is composed of a capacitor in series with a resistor. From the diagram and the property of “capacitor voltage cannot be changed suddenly”, it can be known that when the system is powered on, the RST pin will appear a high level, and the duration of this high level is determined by the circuit. A typical 51 single-chip microcomputer will reset when the high level of the RST pin lasts for more than two machine cycles. Therefore, a proper combination of RC values ​​can ensure a reliable reset.
