MSP430FR2433: Overvoltage to GPIO

U-SK

Part Number: MSP430FR2433

Hello,

If an overvoltage is applied to the terminal, is there a protection diode in the GPIO terminal that misses the overvoltage to the power supply side or GND side?

Regards,

On over voltage, the ESD diodes will shunt the voltage to the VDD rail. In fact, you can power the chip this way, which is why you should not apply voltage to an unpowered chip.
