STM32F405RG 시리즈 문�?�

[CJeon.1]

안녕하세요.

기존�? 사용중�?� 시스템 (PIC 계열) �?서 MCU 만 �?체를 하여 사용�?� 하려고 합니다.

기본 Digital I/O 신호가 5V �?��?�요.

STM32F405RG �?� Datasheet 를 보면서 �?금�?�?� 있어 문�?�를 드립니다.

I/O structure 가 FT �?� 경우, 기존 사용하면 신호를 그대로 연결�?� 해�?� 무방한지요?

아니면 Level shift 회로를 추가하는게 좋�?�지요?

Hi @CJeon.1​ ,

First of all, welcome to ST Community!

As the common used language in this community is English, I tried to translate your question and I got this result:

STM32F405RG series inquiry

Good morning.

I want to use it by replacing only the MCU in the existing system (PIC series).

The basic digital I/O signal is 5V.

I have a question while looking at the datasheet of STM32F405RG, so please inquire

If the I/O structure is FT, is it okay to connect the signal as it is if it is used in the past?

Or is it better to add a level shift circuit?

I am not sure to fully understand it based on this translation. So please explain it more.
