Hello Support,
In Aurix 2G, I can easily understand the meaning of Flash Physical Sector and the corresponding address ranges.
But I am unable to understand what does Flash Logical Sector means for the end user and how Infineon defines it in the User Manual.
Can you please provide me some reference sections within User Manual where PFlash Logical Sector is well described?
I am attaching the snippets from Datasheet for reference.
Best Regards

See page 378:
And Table 133 on page 380: each physical sector is 1 MB.
Non Volatile Memory (NVM): The physical memory used to store information. It is split into sectors:
– Physical Sectors: One physical area of memory is isolated from another area of memory.
– Logical Sectors: A physical sector is further separated into logical sectors. A logical sector is a group of
wordlines for PFLASH and DFLASH, and a single wordline for UCB. A logical sector can be erased with a
single operation. The plain term “sector” means “logical sector”.
And Table 133 on page 380: each physical sector is 1 MB.
