Hi, Can the PAC5271x’s GPIO ports handle current injection?

Hello,

In the datasheet, section15.4, “GPIO Current Injection” it states:

Under normal operation, there should not be current injected into the GPIOs on the device due to the GPIO voltage below ground or above the GPIO supply (note2) Current injected occurs when the GPIO pin voltage is less than -0.3V or when greater than GPIO supply + 0.3V.

In order provide a robust solution when this situation occurs, this device allows a small amount of injected current into the GPIO pins, to avoid excessive leakage or device damage.

For information on the GPIO current injection thresholds, see the absolute maximum parameters for this device. Sustained operation with the GPIO pin voltage greater than the GPIO supply or when the GPIO pin voltage is less than -0.3V may result in reduced lifetime of the device. GPIO current injection should only be a temporary condition.

Note2: VCC33 is the supply for any PC GPIO pin and VCCIO is the supply for any other GPIO pins.

Apologies for the lateness of the reply!
