Extended Command
(1) Fast Mode
MBM29LV080A has Fast Mode function. This mode dispenses with the initial two unlock 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 normal 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 23
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 Setup command (A0H) and data write cycles (PA/PD). (Refer to the
Figure 23 Extended algorithm.)
(3) Extended Sector Protection
In addition to normal sector protection, the MBM29LV080A has Extended Sector Protection as extended function.
This function enable to protect sector by forcing V
ID
on RESET pin and write a command 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 initated by writing the Setup command (60H) into the command register. Then, the
sector addresses pins (A
19
, A
18
, A
17
, and A
16
) 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 250
μ
s. To verify programming of the protection cicuitry, the sector
addresses pins (A
19
, A
18
, A
17
, and A
16
) 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 opetation, it is necessary to set RESET pin to V
IH
.
