STM32G474RB，128K flash，then datasheet show that 512K。And does RB and dual bank mode？

[csinu]

1�?why datasheet show that STM32G474RB has 512K Flash。But STM32CubeMX show 128K？

2�?does the STM32G474RB has dual bank mode？

3�?STM32G474RE，when dual bank，bank1——0x0800 0000~0x0803 FFFF，bank2——0x0804 0000~0x0807 FFFF。

so if STM32G474RB has dual bank mode，then bank1——0x0800 0000~0x0800 FFFF，bank2——0x0801 0000~0x0801 FFFF？？

thanks very much�?�?​

Datasheet covers multiple parts including the RE, and says "UP TO 512K" to account for the range. The die might have the larger amount, with the fractional amount actually tested. If you can touch 0x08040000 without Hard Faulting, assume that's where the second bank starts.

Assume RB is sold as 128KB, Single Bank
