I need low power Design MCU. My STM32F334 is Consuming 70 - 72mA. Does is takes 70mA , or something is wrong ?

Actually measured values ?

Under what conditions ?

According to the datasheet, the 70mA are pretty normal at full speed.

I need low power Design MCU.

The F3 family is NOT a low-power design.

Consider the L0 or L4 family instead.

can you recommend similar MCU ?

I suggest to consider your requirements (peripherals, power consumption, performance), and look at the line-up of the STM32L4xx MCUs.

Or invite ST representatives to make recommendations. I have not use any L4xx yet.
