Extended Command
(1) Fast Mode
MBM29DL16XTE/BE 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. The first cycle must contain the bank address. (Refer to the Figure 28.) 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 28.)
(3) Extended Sector Group Protection
In addition to normal sector group protection, the MBM29DL16XTE/BE has Extended Sector Group
Protection as extended function. This function enable to protect sector group 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 group protection in this mode. The extended
sector group protection 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 group 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 group to be protected
(recommend to set V
IL
for the other addresses pins), and write extended sector group protection command
(60H). A sector group is typically protected in 250
μ
s. To verify programming of the protection circuitry, the
sector group 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 group protection command (60H) again. To terminate the operation, it is necessary to set RESET pin
to V
IH
. (Refer to the Figures 20 and 29.)
(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. The bank address
should be set when writing this command. Then the device information can be read from the bank, and an
actual data of memory cell be read from the another bank. 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. (See Table 15.)
