Extended Command
(1) Fast Mode
MBM29LV160TE/BE 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) Extended Sector Protection
In addition to normal sector protection, the MBM29LV160TE/BE 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 250
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
.
(4) 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.
