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
Fast Mode.
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.)
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
Unlike conventional procedure, it is not necessary to force V
RESET pin requires V
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
should be set to the sector to be protected (recommend to set V
extended sector protect command (60H). A sector is typically protected in 250 s. To verify programming of
the protection circuitry, the sector addresses pins (A
(0, 1, 0) should be set and write a command (40H). Following the command write, a logical “1” at device
output DQ
repeat to write extended sector protect command (60H) again. To terminate the operation, it is necessary
to set RESET pin to V
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
