Extended Command
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.
(1) Fast Mode
(2) Fast Programming
(3) CFI (Common Flash Memory Interface)
MBM29PL160TD/BD 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 22 Extended algorithm.) The V
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 22 Extended algorithm.)
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
