Hello,
Page size for S25FL128SAGNFI000 is 256B.
You can confirm the page size from the device Model Number in its OPN(Ordering Part Number).
For S25FL128SAGNFI000, Model Number is 0 = Uniform 64-KB sectors.
See following Notes 62 in the datasheet.
62. Uniform 64-KB sectors = A hybrid of 32 x 4-KB sectors with all remaining sectors being 64 KB, with a 256B programming buffer

Nada

Hi , Thank you so much for replying.
There is another question, how do I confirm that the chip(S25FL128SAGNFI000) is Bottom 4-kbyte Sectors or Top 4-kbyte Sectors?

Hi,
Please refer to section 7.5.2 Configuration Register 1(CR1) in the datasheet page 50~52.
You can try to read the contents of CR1 register using command RDCR (35h) to confirm.
TBPARM CR1[2] defines the logical location of the parameter block. When TBPARM is set to a 1 the parameter block is in the top of the memory array address space. When TBPARM is set to a 0 the parameter block is at the Bottom of the array. TBPARM is OTP and set to a 0 when it ships from Cypress. If TBPARM is programmed to 1, an attempt to change it back to 0 will fail and set the Program Error bit (P_ERR in SR1[6]).
Thanks,
Nada

Hi , Nada, Thank you so much for replying.
It really helps a lot...
But so sorry to bother you , thers is another question that i don't konw..
At the Sector Erase part, after the erase command is sent to the chip, the internal erase cycle will be initiated, and the WIP bit will indicate
a 0 when the erase cycle has been completed.
But where could I know the how long is the erase cycle? or how long the sector erase command takes to complete the sector erase step(after the CS# is set to high)?
And for the Bulk erses commond, the erset cycle is the same time?

Hi,
Sorry for the delayed. I believe my colleague had answered your queries in the other thread you created.
For S25FL128SAGNFI000,how long the erase cycle takes at the erase command?
