How to connect power supply pins of SPC582B?

Yannek

Hi,

Is there any hardwade design guideline for SPC58 like there is AN3024 application note for SPC56?

There is a lot of power supply signals in SPC582B...E1 and very little grounds...

VDD_LV_FLA

VDD_LV

VDD_HV_IO_MAIN

VDD_HV_ADR_S

VDD_HV_ADV_S

VDD_HV_OSC

VDD_HV_IO_MAIN

VDD_HV_FLA

VSS_HV_ADV_S

VSS_HV_ADR_S

VSS_HV_OSC

Which should be connected and which not?

I found it strange that there is no ordinary ground signal (different than in SPC56). Which ground is THE ground? OSC?

In SPC56 I had to put decoupling capacitors between adjacent VDD_LVs and VSS_LVs. But in SPC58 there is no VSS_LV and VDD_LV is far away from any ground pin...

Thanks in advance,

Yannek

Hello Yannek ,

I am checking in the documentation database in order to find the document requested.

Hi Erwan,

Any update in this topic, please?

For me it would be enough to know which pins should be tied to VCC and which should have only capacitors connected.

Best,

Yannek
