[STSPIN32G4] Radiated Emission Issue

[DKim.39]

Hello I want support for STSPIN32G4 EMI Issue

I took tests for Farfield EMI Report at STSPIN32G4 Standby condition
Report shows QP are over than Limit at 190.547MHz, 253.803MHz

and I also get similar result by using Near-field prove(Proved Noise Peaks : 185.91, 123.94, 247.88, 309.84MHz) this result are same at evspin32g4-dual(also Flash Erase conditions results)

I guess 62 MHz harmonic noise occurs between STM32G431 and STSPIN32G4 Internal Control logic Because I observe noise when Voltage input to VM and REGIN for the (in 3.3V externally supplied circuit)

I want to know how could i solve this problem(Resolving EMI noise)

Hello GMA,

I have the same problem using STSPIN32G4 and I cannot view the answer.

Could you show the support team answer, please?

Thank you very much
