USING STM32L412-RB-P WITH NO CRYSTAL - ONLY INTERNAL RC CLOCK

[DLe.5]

DOES ANY ONE SUCCESSFULLY DESIGN THE STM32L4XX WITH INTERNAL CLCK ONLY ?

ANY PROBLEM WITH ITS POWER CONSUMPTION?

PLEASE SHARE YOUR INPUT

THANKS

I use STM32L412 w/o crystal for serial communication. Power consumption is not an issue in that design, but also not a problem. What problem do you expect/experience?

Currently using an STM32L433 with internal oscillator/HSI. Gernerating PWM signals, capturing, and UART/SPI are functioning with no issues. Seems stable. Low power consumption. First project without HSE
