Hi,

You can find this info in reference manual:

For erase operations, only blocks that are selected and unlocked determine the RWW partitions being written. in table 3.3.

I want to know what size of the smallest sector can be earse?It is 512 byte?

It is size of smallest block. what do you mean by sector?

      And one block is N*sector, the N can be any number?

Could you point me on sectors in our manual? Are you talking about flash memory?

regards,

Peter
