Address format A14-A0 (Hex), Addresses A15 - A19 can be VIL or VIH, but no other value, for the Command sequence for SST39LF/VF080. Addresses A15 - A20 can be VIL or VIH, but no other value, for the Command sequence for SST39LF/VF016. 2. WA = Program Byte address 3. SAX for Sector-Erase; uses AMS-A12 address lines BAX, for Block-Erase; uses AMS-A16 address lines AMS = Most significant address AMS = A19 for SST39LF/VF080 and A20 for SST39LF/VF016 4. The device does not remain in Software Product ID Mode if powered down. 5. With AMS-A1 =0; SST Manufacturer’s ID= BFH, is read with A0 = 0, SST39LF/VF080 Device ID = D8H, is read with A0 = 1 SST39LF/VF016 Device ID = D9H, is read with A0 = 1 6. Both Software ID Exit operations are equivalent TABLE 5: CFI QUERY IDENTIFICATION STRING1 FOR SST39LF/VF080 AND SST39LF/VF016 1. Refer to CFI publication 100 for more details. Address Data Data 10H 51H Query Unique ASCII string “QRY” 11H 52H 12H 59H 13H 01H Primary OEM command set 14H 07H 15H 00H Address for Primary Extended Table 16H 00H 17H 00H Alternate OEM command set (00H = none exists) 18H 00H 19H 00H Address for Alternate OEM extended Table (00H = none exits) 1AH 00H T5.3 396 |
