10 / 25 page Operation STM1810/1811/1812/1813/1815/1816/1817/1818 10/25 threshold and lasts 20 µs or less will not cause a reset pulse. A 0.1 µF bypass capacitor mounted as close as possible to the VCC pin provides additional transient immunity. 2.5 Valid RST output down to VCC = 0 V When VCC falls below 1 V, the RST output no longer sinks current, but becomes an open circuit. In most systems this is not a problem, as most MCUs do not operate below 1 V. However, in applications where RST output must be valid down to 0 V, a pull-down resistor may be added to hold the RST output low (see Figure 12). This resistor must be large enough to not load the RST output, and still be small enough to pull the output to ground. A 100 k Ω resistor is recommended. Note: The same situation applies for the active-high RST of the STM1810/1812. A 100 k Ω pull-up resistor to VCC should be used if RST must remain valid for VCC < 1.0 V. Figure 8.
