Misalignment between STM32CubeMX and the datasheet of STM32G030J6 regarding USART modules

I am interested in how many USART modules are available in the STM32G030J6.

Datasheet contains contradictions.

According to table 12 (pages 32-34) we get the following:

USART1_TX 8 pin

USART1_RX 1 pin

USART2_TX 4 pin

USART2_RX 8 pin

According to Figure 6 (page 30) and Table 13 (page 35) we get the following:

USART1_TX 5 pin

USART1_RX 1 pin

USART2_TX 4 pin

USART2_RX 8 pin

STM32CubeMX indicates that only USART1 is available.

How right?

Hi. Only one USART in the STM32G030J6. Pin "PA8/PA11[PA9]/PB0/PB1" don`t have  USART1_TX.

STM32CubeMX make this:

Pin "PA8/PA11[PA9]/PB0/PB1" have USART1_TX

How right?

What is your CubeMX Version?

Hello @AShap.5​ ,

This seems to be a limitation on STM32CubeMX side as it is possible to use USART2 on pins 4 and 8 of STM32G030Jx SO8N package.

This will be reported to our STM32CubeMX team.
