In datasheet it is mentioned as 3.3V or max 3.6V.But as my product is ready & SW is ready with STM32L431KBU6 uC, just as cost saving view (Remove level shifter IC) & to have all IC's on same voltage(+5V), I am looking for same uC with only supply wor...
Thanks for your response.Actually I want to drive SPI slave from STM32 uC (Master) .This STM32L431KBU6 works on 3.3V & Slave circuit works on 5V.To avoid money in level shifter IC for this I was just looking for same uC specification with just suppl...
