125 / 149 page  Document Number: 001-98283 Rev. *M Page 124 of 148 S25FL128S/S25FL256S 11.2 Device ID and Common Flash Interface (ID-CFI) Address Map 11.2.1 Field Definitions Table 54. Manufacturer and Device ID Byte Address Data Description 00h 01h Manufacturer ID for Cypress 01h 20h (128 Mb) 02h (256 Mb) Device ID Most Significant Byte - Memory Interface Type 02h 18h (128 Mb) 19h (256 Mb) Device ID Least Significant Byte - Density 03h 4Dh ID-CFI Length - number bytes following. Adding this value to the current location of 03h gives the address of the last valid location in the ID-CFI address map. A value of 00h indicates the entire 512-byte ID-CFI space must be read because the actual length of the ID-CFI information is longer than can be indicated by this legacy single byte field. The value is OPN dependent. 04h 00h (Uniform 256-kB sectors) 01h (4-kB parameter sectors with uniform 64-kB sectors) Sector Architecture 05h 80h (FL-S Family) Family ID 06h xxh ASCII characters for Model Refer to Section 12. Ordering Information on page 141 for the model number definitions. 07h xxh 08h xxh Reserved 09h xxh Reserved 0Ah xxh Reserved 0Bh xxh Reserved 0Ch xxh Reserved 0Dh xxh Reserved 0Eh xxh Reserved 0Fh xxh Reserved Table 55. CFI Query Identification String Byte Address Data Description 10h 11h 12h 51h 52h 59h Query Unique ASCII string “QRY” 13h 14h 02h 00h Primary OEM Command Set FL-P backward compatible command set ID 15h 16h 40h 00h Address for Primary Extended Table 17h 18h 53h 46h Alternate OEM Command Set ASCII characters “FS” for SPI (F) interface, S Technology 19h 1Ah 51h 00h Address for Alternate OEM Extended Table |
