about the maximum allowed continuous current of S12ZVL

Hello,

In S12ZVL Reference Manual,

Maximum allowed continuous current on PP1, PP3 and PP5 is specified -20 ~ 10mA as I_EVDD.

Which understanding is correct about this I_EVDD?

- I_EVDD is the spec for each port

- I_EVDD is the spec of the current sum of PP1, PP3 and PP5

Hello

The S12ZVL Reference Manual has not yet been released, so it is not clear exactly which information you are referring to.

However to clarify a few points.

PP1, PP3 and PP5 are not EVDD pins. PP1, PP3 and PP5 have increased current driving capability to VSSX ground.

PP7 is the EVDD1 pin which has increased current driving capability to VDDX.

The EVDD1 specification has a range of -20mA to +10mA for that pin.

The PP1,PP3 and PP5 spec. maximum is +25mA for each pin.

The total maximum current of 80mA (absolute maximum ratings) must also be taken into consideration.

The first official reference manual shall be published soon.

DPB-san,

Thank you for your helpful information.

It makes sense to me. I can understand clearly!!
