Hi.

I have a few questions about GPIO DC Characteristics.

1,What is the voltage range when the 8mA load at VDDS=3.0V is applied to the high drive GPIO terminals.

2,What is the voltage range when the 4mA load at VDDS=3.0V is applied to the GPIO terminasl.

3,What is the voltage range when the no load at VDDS=3.0V is applied to the GPIO terminals.

Please let me know not only the typical value but also the maximum and minimum values.

Hi,

The typical values are specified since this is normally sufficient for the majority of customers.

Can you share your schematic so we can understand your concern with the GPIO voltage levels ?

Thanks,

Richard

Hi, Richard

I don't know because the circuit diagram has not been disclosed by the customer.

I think that the customer wants to know whether the voltage level of the peripheral circuit (for example, controlled by the SPI of the microcomputer) has design issues.

Hi,

If customer still sees this as an issue please send me their schematic for review. OK to send as a private message if you do not want to share schematic on the forum.

Regards,

Richard
