happens later , while the command (data) is latched
on the rising edge of WE or CE, whichever happens
first.
Sector addresses selected are
loaded into
internal register on the sixth falling edge of WE or CE,
whichever happens later.
Each successive sector
load cycle started by the falling edge of WE or CE,
whichever happens later must begin within 50us from
the rising edge of the preceding WE or CE, whichever
happens first. Otherwise, the loading period ends and
internal auto sector erase cycle starts. (Monitor Q3 to
determine if the sector erase timer window is still
open, see section Q3, Sector Erase Timer.) Any
command other than Sector Erase (30H) or Erase
Suspend (B0H) during the time-out period resets the
device to read mode.
ERASE SUSPEND
This command only has meaning while the state ma-
chine is executing Automatic Sector Erase operation,
and therefore will only be responded during Automatic
Sector Erase operation. When the Erase Suspend com-
mand is issued during the sector erase operation, the
device requires a maximum 20us to suspend the sector
erase operation. However, When the Erase Suspend com-
mand is written during the sector erase time-out, the
device immediately terminates the time-out period and
suspends the erase operation. After this command has
been executed, the command register will initiate erase
suspend mode. The state machine will return to read
mode automatically after suspend is ready. At this time,
state machine only allows the command register to re-
spond to the Erase Resume, program data to, or read
data from any sector not selected for erasure.
The system can determine the status of the program
operation using the Q7 or Q6 status bits, just as in the
standard program operation. After an erase-suspend pro-
gram operation is complete, the system can once again
read array data within non-suspended blocks.
ERASE RESUME
This command will cause the command register to clear
the suspend state and return back to Sector Erase mode
but only if an Erase Suspend command was previously
issued. Erase Resume will not have any effect in all
other conditions. Another Erase Suspend command can
be written after the chip has resumed erasing.
QUERY COMMAND AND COMMON FLASH
INTERFACE (CFI) MODE
MX29LV640U is capable of operating in the CFI mode.
This mode all the host system to determine the manu-
facturer of the device such as operating parameters and
configuration. Two commands are required in CFI mode.
Query command of CFI mode is placed first, then the
Reset command exits CFI mode. These are described in
Table 3.
The single cycle Query command is valid only when the
device is in the Read mode, including Erase Suspend,
Standby mode, and Read ID mode; however, it is ignored
otherwise.
The Reset command exits from the CFI mode to the
Read mode, or Erase Suspend mode, or read ID mode.
The command is valid only when the device is in the CFI
mode.
