Extended Command
(1) Fast Mode
MBM29LV002TC/BC has Fast Mode function. This mode dispenses with the initial two unclock cycles
required in the standard program command sequence by writing Fast Mode command into the command
register. In this mode, the required bus cycle for programming is two cycles instead of four bus cycles in
standard program command. (Do not write erase command in this mode.) The read operation is also executed
after exiting this mode. To exit this mode, it is necessary to write Fast Mode Reset command into the command
register. (Refer to the Figure 24 Extended algorithm.) The V
CC
active current is required even CE = V
IH
during
Fast Mode.
(2) Fast Programming
During Fast Mode, the programming can be executed with two bus cycles operation. The Embedded Program
Algorithm is executed by writing program set-up command (A0H) and data write cycles (PA/PD). (Refer to
the Figure 24 Extended algorithm.)
(3) Extended Sector Protection
In addition to normal sector protection, the MBM29LV002TC/BC has Extended Sector Protection as extended
function. This function enable to protect sector by forcing V
ID
on RESET pin and write a commnad sequence.
Unlike conventional procedure, it is not necessary to force V
ID
and control timing for control pins. The only
RESET pin requires V
ID
for sector protection in this mode. The extended sector protect requires V
ID
on RESET
pin. With this condition, the operation is initiated by writing the set-up command (60H) into the command
register. Then, the sector addresses pins (A
17
, A
16
, A
15
, A
14
, and A
13
) and (A
10
, A
6
, A
1
, A
0
) = (0, 0, 1, 0) should
be set to the sector to be protected (recommend to set V
IL
for the other addresses pins), and write extended
sector protect command (60H). A sector is typically protected in 150
μ
s. To verify programming of the
protection circuitry, the sector addresses pins (A
17
, A
16
, A
15
, A
14
, and A
13
) and (A
10
, A
6
, A
1
, A
0
) = (0, 0, 1, 0)
should be set and write a command (40H). Following the command write, a logical “1” at device output DQ
0
will produce for protected sector in the read operation. If the output data is logical “0”, please repeat to write
extended sector protect command (60H) again. To terminate the operation, it is necessary to set RESET
pin to V
IH
.
