MCU support both 1.8 V GPIO and 3.3 V GPIO

[KSu.1]

Hi, I am looking for MCU which support 1.8 V GPIO and 3.3 V GPIO,

My target is about 20 pin 1.8 V GPIO and about 10 pin 3.3 GPIO.

After my search, I think STM32F0x8 can meet my requirement.

I want to know are there STM32 low power series MCU or STM32 High Performance MCUs

can also meet my requirement?

Flash need > 128K, RAM need > 20K. It's better to have USB.

Thanks

Ken

You can check the STM32L552, which is providing a separate pin VDDIO for exactly that purpose, 256KB or 512KB Flash, 192+64KB RAM and USB 2.0 Device FS Crystal Less.

The L4+ parts has a GPIOG bank that can be powered independently via a VCCIO pin
