be programmed to sectors that are not erase-suspended. Successively reading from the erase-suspended sector
while the devices are in the erase-suspend-program mode will cause DQ
2
to toggle. The end of the erase-
suspended Program operation is detected by the RY/BY output pin, Data polling of DQ
7
, or the Toggle Bit (DQ
6
)
which is the same as the regular Program operation. Note that DQ
7
must be read from the Program address
while DQ
6
can be read from any address.
To resume the operation of Sector Erase, the Resume command (30H) should be written. Any further writes of
the Resume command at this point will be ignored. Another Erase Suspend command can be written after the
chip has resumed erasing.
Extended Command
(1) Fast Mode
MBM29LV160T/B has Fast Mode function. This mode dispenses with the initial two unlock cycles required
in the standard program command sequence 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 26 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 26 Extended algorithm.)
(3) CFI (Common Flash Memory Interface)
The CFI (Common Flash Memory Interface) specification outlines device and host system software
interrogation handshake which allows specific vendor-specified software algorithms to be used for entire
families of devices. This allows device-independent, JEDEC ID-independent, and forward-and backward-
compatible software support for the specified flash device families. Refer to CFI specification in detail.
The operation is initiated by writing the query command (98H) into the command register. Following the
command write, a read cycle from specific address retrives device information. Please note that output data
of upper byte (DQ
8
to DQ
15
) is “0” in word mode (16 bit) read. Refer to the CFI code table. To terminate
operation, it is necessary to write the read/reset command sequence into the register.
(4) Extended Sector Protect
In addition to normal sector protection, the MBM29LV160T/B 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
19
, A
18
, A
17
, A
16
, A
15
, A
14
, A
13
and A
12
) and (A
6
, A
1
, A
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
19
, A
18
, A
17
, A
16
, A
15
, A
14
, A
13
and A
12
) and (A
6
, A
1
, A
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
