PTN3356 SWOUT connection to PGND

[masahirokiniwa]

Hi,

I found the difference of schematics between Data Sheet (Fig.4 and 5) and Application note AN11590 (Fig.2 and 3).

Could you tell me which schematics is a correct reference?

In the Data Sheet, SWOUT is not connecting to 0.1uF PGND by capacitor (so PVDD33 is connecting to PGND by 0.1uF capacitor) as below.

In AN11590, SWOUT is connecting to PGND by 0.1uF capacitor as below.

Best regards,

M.Kiniwa

Hi Masahiro,

The 0.1uF capacitor needs to be connected from pin 30 (PVDD33) to pin 32 (PGND) as shown correctly in the datasheet. The AN11590 will be updated to fix this error in the schematic.

Best regards,

Tomas
