We have a new product and the MCU is STM32F429VIT6, I checked the datasheet, it has 4 uart/4 usart, our product need to connect 6 device by uart interface, so could I use the MCU to finish the reqirement? what should i need to be considered?

USART can be used as a UART. The chip has 8 UARTs. You can use 6 of them.

Hi TDK,

Thank you so much, could you kindly help to confirm the below design is right?

USART:USART1,USART6,USART2

UART:UART4,UART5,UART6,UART7,UART8

You have both USART6 and UART6 listed. It's USART6.

Use STM32CubeMX to do the pinout and verification of each peripheral.
