Hello,As VREF is connected to VDDA, I suggest to connect VDDA to an external reference voltage. The power consumption on VDDA is low as it supplies only ADC, DAC, comparators and opamp (cf datasheet).Bertrand

Hello, Yes this feature (VDDIO2 with IOs going down to 1.08V) is also available on STM32L4 and STM32U5. Bertrand

Hello,There is a high probability that some IOs are not correctly settled. I saw you set all IOs as pull-down but if there is an external pull-up you will see a power consumption.Check the schematics and set each IO accordingly.Bertrand

Hello,The STM32L4 and STM32L4+ family is fully in production and no issue to deliver all the parts. Have you placed an order ? The distributors put more on the shelf the 85°C version ("6" more generic) rather than the 125°C ("3"). Thanks,Bertrand
