What is the flash configuration of the 1MByte STM32U5xx MCU's?

[Nick van IJzendoorn]

The reference manual of the STM32U575xx gives the flash configuration in `Table 44. Flash module 2-Mbyte dual bank organization` but this only takes into account the 2MByte flash size.

We use the STM32U575CG which only has 1MByte.

Is it still dual bank with 64 pages of 8KB per bank?

Or does it only have 1 bank with 128 pages of 8KB?

Or has it 2 banks with 128 pages of 4KB?

[Nick van IJzendoorn]

Nevermind, according to the HAL source code it's 64 pages of 8KB per bank of which there are 2.

Hello @Nick van IJzendoorn​ ,

For 1MB it is dual bank if the DUALBANK option is set. In this case it is 64 pages of 8KB per bank, but there is an HW address remap so that the 1MB addresses are still contiguous even in dual bank mode.
