A23-A16 are “Don't Care” for SST45VF512, A23-A17 are “Don't Care” for SST45VF010, A23-A18 are “Don't Care” for SST45VF020. 2. A16-A12 are used to determine sector address, A11-A8 are don't care. 3. With A15-A1 = 0, SST45VF512 Device ID = 41H, is read with A0 = 1. With A16-A1 = 0, SST45VF010 Device ID = 45H, is read with A0 = 1. With A17-A1 = 0, SST45VF020 Device ID = 43H, is read with A0 = 1.
