Hi Md Nasir,

Thank you for contacting Cypress Semiconductor.

As you will see mentioned in the S70FL01GS datasheet General Description section, "This document contains information for the S70FL01GS device, which is a dual die stack of two S25FL512S die. For detailed specifications, refer to the discrete die datasheet provided in the Affected Documents/Related Documents table."

Detailed description of the commands will be available in the S25FL512S datasheet here - https://www.cypress.com/file/177971/download

hello ,

i have concern regarding Write operation on flash(S70FL01GS)

1) is it possible to write  Same byte  in this chip without erase(like 1->1 or 0 -> 0)?

2) if same byte write is not allowed then is it possible to write consecutive byte write

for example i have following data in sector

Data  in  sector (00)

offset :0 , 1 ,  2 , 3, 4,  5 , 6 , 7 , .....................512

         ------------------------------------------------------

Data   01,02,03,04,FF,FF,FF,FF.........................FF

         ----------------------------------------------------

New data to be write in  sector (00)

offset :0 , 1 ,  2 , 3, 4,  5 , 6 , 7 , .....................512

         ------------------------------------------------------

Data   01,02,03,04,05,06,07,08........................FF

         ----------------------------------------------------

can we write data bytes(05,06,07,08.) to  4,  5 , 6 , 7 offset without erase, does it make any effect on offset 0 , 1 ,  2 , 3 data bytes?

We would appreciate if you would share your feedback regarding above concern.

When we perform above operation does it decrease endurance of corresponding sector(Does it perform Erase operation in Background)??

If u have any support contact number so please send me ??

Thanks You.
