Valid RST output down to V
When V
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. 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 kΩ resistor is recommended.
The same situation applies for the active-high RST of the STM810/812. A 100 k
resistor to V
CC
falls below 1 V, the RST (STM809/811) output no longer sinks current, but
CC
should be used if RST must remain valid for V
