Chip's 3v
WebMar 9, 2015 · If the chip Vcc is 3 volts, and you apply 5 volts to an input pin, the protection diode on that pin will try to pull the 3 volt Vcc towards 5 volts. This may destroy that diode, and/or may cause higher than expected Vcc voltages on other parts of the circuit. – Peter Bennett Mar 8, 2015 at 21:38 Add a comment -1 WebJan 23, 2024 · The 3.3v regulator circuit on ESP32 boards can be a little... weak, depending on the supplier, lot, phase of the moon...

I have a board design with at STM32F427 that operates off of two voltage supplies: 3.3V and 5V. The 3.3V regulator is daisy chained off of the 5V regulator which means that the 5V logic comes up before the processor.
WebMay 6, 2024 · This limited current and the parasitic capacitance modify the signal waveforms. Depending on the exact capacitance of your circuit you may not achieve reliable communications with the Flash chip. The 10k resistor limits the maximum current to 0.5mA as the voltage at the tap point increase this drive current is reduced. WebAs power-supply voltages dropped from +5V to +3.3V and lower, single-supply RS-232 transceivers kept pace. The transceivers that are powered from voltages ranging from 3.0V to 5.5V use two regulated charge pumps instead of the unregulated types used in the parts powered by only +5V.
