How to make S32K344 get lowest current consumption in SOC_STANDBY mode

KerryJ · ‎09-01-2022

I used S32K344,

IDE is S32DS3.4 ,

RTD is S32K3 RTD AUTOSAR 4.4 VERSION 2.0.0

I Set S32K344 in SOC_STANDBY mode by Power_Ip_SetMode(soc_standby), and I Found the current consumption is 14mA, the request is less 3 mA.

what step I lost? like deinitial some mode used? or switch clock to FISR? I tried so many but not worked!

I wish there is example project to learn it, Hope to get your help, thanks.

Thanks you very much.

I find out my problem. there are two pin config as SPI_OUT which increase current consumption in SOC_STANDBY mode. So I config those 2 pin as GPIO_OUT_LOW before enter SOC_STANDBY mode. and the problem is solved!
