the same. Sector addresses must be held constant during the WE pulse. See figures 14 and 21 for sector
protection waveforms and algorithm.
To verify programming of the protection circuitry, the programming equipment must force V

. Scanning the sector addresses (A

) while (A

) = (0, 0, 1, 0) will produce a logical “1” code at device output DQ
0
for a protected sector. Otherwise the
devices will read 00H for unprotected sector. In this mode, the lower order addresses, except for A
0
, A
1
, A
6
, and
A
10
are DON’T CARES. Address locations with A
1
= V
IL
are reserved for Autoselect manufacturer and device
codes.
It is also possible to determine if a sector is protected in the system by writing an Autoselect command. Performing
a read operation at the address location XX02H, where the higher order addresses (A
17
, A
16
, A
15
, A
14
, and A
13
)
are the sector address will produce a logical “1” at DQ
0
for a protected sector. See Tables 3.1 and 3.2 for Autoselect
codes.
Temporary Sector Unprotection
This feature allows temporary unprotection of previously protected sectors of the MBM29LV002T/002B devices
in order to change data. The Sector Unprotection mode is activated by setting the RESET pin to high voltage
(12 V). During this mode, formerly protected sectors can be programmed or erased by selecting the sector
addresses. Once the 12 V is taken away from the RESET pin, all the previously protected sectors will be protected
again. See figure 15 and 22.
