STM32F103RDT6 Uart details

Mom.1

Hi team,

I am using STM32F103RDT6 for my project. I would like to know the details of UART in the MCU. in the datasheet it shows 5 USART interface is possible. At the same time 2 UART is also mention in the datasheet.

So my doubt is that can I use the 5 USART as UART? If yes Why 2 UART mentions separately in the datasheet?

Warm regards,

Monisha OM

The die is the same between multiple packages, the package pin count ultimately limits the peripherals that can be exposed.

USART1, USART2, USART3

UART4 and UART5

You'd need to walk the pin list to see those exposed.
