32M FLASH MANUFACTURER/DEVICE ID TABLE
32M FLASH SECURED SILICON SECTOR TABLE

L=logic low= VIL, H=Logic High= VIH, VID = 9 ± 0.5V, X=Don’t Care (either L or H, but not floating!), SA=Sector
Addresses
Note:
1. A8 = H is recommended for Manufacturing ID check. If a manufacturing ID is read with A8=L, the chip will output
a configuration code 7Fh.
2. A9 = VID is for HV A9 Autoselect mode only. A9 must be ≤ Vcc (CMOS logic level) for Command Autoselect
Mode.
3. 32M FLASH SECURED SILICON SECTOR TABLE is valid only in Secured Silicon Sector.
4.
