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

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 μs. 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
of upper byte (DQ
operation, it is necessary to write the read/reset command sequence into the register.
