Device ID and Common Flash Interface (ID-CFI) ASO Map

The Device ID portion of the ASO (word locations 0h to 0Fh) provides manufacturer ID, device ID, Sector

Protection State, and basic feature set information for the device.

ID-CFI Location 02h displays sector protection status for the sector selected by the sector address (SA) used

in the ID-CFI enter command. To read the protection status of more than one sector it is necessary to exit the

ID ASO and enter the ID ASO using the new SA. The access time to read location 02h is always tACC and a

read of this location requires CE# to go High before the read and return Low to initiate the read

(asynchronous read access). Page mode read between location 02h and other ID locations is not supported.

Page mode read between ID locations other than 02h is supported.

For additional information see ID-CFI ASO on page 35.

Sector Protection State (1= Sector protected, 0= Sector unprotected). This protection state

is shown only for the SA selected when entering ID-CFI ASO. Reading other SA provides

undefined data. To read a different SA protection state ASO exit command must be used

and then enter ID-CFI ASO again with the new SA.
