Solved: S70FS01GS Bulk Erase (0xFE command) - Page 2 - Infineon Developer Community

Hello,

I would like to bulk erase the complete memory ( i.e. both the devices FS512S).

Since I am pretty new to this Flash memory , I would like to know if anything should be configured before i use the command?

Could I know the steps if Configuration of the lower or Upper address is necessary before bulk erase?

If so could I know the steps to achieve Bulk erase?

Regards,

Edwin

Hi Edwin,

If you want to perform Bulk Erase operation on S70FS01GS, it will be a two step process. You will have to erase one die at a time.

For erasing the lower die the command sequence should be -

CS# LOW

WREN command (06h)

CS# HIGH

CS# LOW

BEA command (FEh)

Any address from lower die (say 0x0000000)

CS# HIGH

For erasing the upper die the command sequence should be -

CS# LOW

WREN command (06h)

CS# HIGH

CS# LOW

BEA command (FEh)

Any address from upper die (say 07FFFFFFh)

CS# HIGH

Typically, it will take 220 seconds to erase one die, but the maximum bulk erase time can go up to 720 seconds.

Thanks and Regards,

Apurva
