The manufacturer and device codes may also be read via the command register, for instances when the
MBM29LV080A is erased or programmed in a system without access to high voltage on the A
9
pin. The command
sequence is illustrated in Table 6. (Refer to Autoselect Command section.)
Byte 0 (A
0
= V
IL
) represents the manufacture’s code (Fujitsu = 04H) and byte 1 (A
0
= V
IH
) represents the device
identifier code MBM29LV080A = 38H. All identifiers for manufactures and device will exhibit odd parity with DQ
7
defined as the parity bit. In order to read the proper device codes when executing the autoselect, A
1
must be
V
IL
. (See Tables 3.1 and 3.2.)
In order to determine which sectors are write protected, A
1
must be at V
IH
while running through the sector
addresses; if the selected sector is protected, a logical ‘1’ will be output on DQ
0
(DQ
0
= 1).
