PSoC 4 MCU

Hi.

My customer use PSoC 4100S Plus (CY8C4127AZI-S455).

Please tell us of GPIO Output leakage current.

Drive mode uses "Strong Drive", "Open Drain Drives High", and "Open Drain Drives Low".

What is the leakage current when the output is OFF, that is, when it is in the high impedance state?

I understand that Input leakage current is 2nA.

Does this change under the condition of 5V, -10 ~ 70 ℃?

Best Regards.

Dear Asanuma-san,

We notice max of -4.138nA leakage at 80C,5.5V across 3 samples. We expect the current to be around this region. I hope this data is helpful.

Best Regards,

Hi,

GPIO pin leakage current is irrespective of the pin being configured for input or output. The value of 2nA is the absolute value. It an be +/- 2nA, which means the current can flow into the device or flow out of the device. As of now the value is characterized only at 25℃.

Dear Vasanth-san

Thank you for your answer.

I understand that the leakage of the output current is the same as the leakage of the input current.

How much do you expect Input leakage current to change with VDDD and temperature?
