Notes:
329 PGM T4.2
(1) Address format A14-A0 (Hex), Addresses A15, A16, A17, A18 and A19 are “Don’t Care” for Command sequence.
(2) SAx for sector erase; uses A19-A11 address lines
BAx, for block erase; uses A19-A15 address lines
(3) WA = Program word address
(4) Both Software ID Exit operations are equivalent
(5) DQ15 - DQ8 are “Don’t Care” for Command sequence
Notes for Software ID Entry Command Sequence
1. With A19 -A1 =0; SST Manufacturer Code = 00BFH, is read with A0 = 0,
SST39VF160Q/VF160 Device Code = 2782H, is read with A0 = 1.
2. The device does not remain in Software Product ID Mode if powered down.
