SPC58EC80E5 current limit on 5v and 3.3v pins

Hi there,

I was looking for the current limit on the 5v and 3.3v pins of the SPC58E80E5 board (I check in the user manual) but I can't figured out.

Which ones are they? Where I can get this information?

Hello,

you can find current limits in SPC58 C line datasheet:

Datasheet - SPC584Cx, SPC58ECx - SPC58 C Line - 32 bit Power Architecture automotive MCU Dual z4 cores 180 MHz, 4 MBytes Flash, HSM, ASIL-B (st.com)

Best Regards,

I'm not sure if the values below are the ones I was looking for (this is page 34 of the datasheet you pointed to me)

Hello,

the two parameters you need to satisfy for reliability and functionality are the ones passed in DS rev8 4.8.3.

"In order to ensure device reliability, the average current of the I/O on a single segment

should remain below the IRMSSEG maximum value.

In order to ensure device functionality, the sum of the dynamic and static current of the I/O

on a single segment should remain below the IDYNSEG maximum value."

Best Regards,

Giuseppe
