Current consumption in stop mode 1 using STM32G0C1. Does anyone get less than 1mA?

Does anyone get good results in current consumption with STM32G0C1?

I'm using stop mode 1, HSI as clock source and can't get below 1mA on current consumption.

Hello,

May you check you have no PLL ON? It is not switched off by the stop entry if I remember correctly.

Thanks Antoine.

Still can get less than 1mA consumption in stop mode.

Looks like PLL Disable doesn't help.

This is how I am switching to Stop Mode 1:

HAL_SuspendTick();
 
LL_RCC_PLL_Disable();
 
HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);

BTW it goes to Shutdown Mode very well (consumption below 1uA).

Any ideas what I'm doing wrong?

Maybe you should check that PWR controller clock is ON. If not clocked I think product only goes to sleep as just core can pass the information. You can switch ON this clock through LL or by hitting the bit.

I think the example in cube library should be properly tested and lead you to Stop 1 correctly. May you test this if you fail with clock activation?

Thank you and regards,

Antoine
