MX29LV320C T/B
completed as indicated by Data# Polling or Toggle Bit. If
Q3 is low ("0"), the device will accept additional sector
erase commands. To insure the command has been ac-
cepted, the system software should check the status of
Q3 prior to and following each subsequent sector erase
command. If Q3 were high on the second status check,
the command may not have been accepted.
If the time between additional erase commands from the
system can be less than 50us, the system need not to
monitor Q3.
RY/BY#:READY/BUSY# OUTPUT
The RY/BY# is a dedicated, open-drain output pin that
indicates whether an Embedded Algorithm is in progress
or complete. The RY/BY# status is valid after the rising
edge of the final WE# pulse in the command sequence.
Since RY/BY# is an open-drain output, several RY/BY#
pins can be tied together in parallel with a pull-up resistor
to VCC .
If the output is low (Busy), the device is actively erasing
or programming. (This includes programming in the Erase
Suspend mode.) If the output is high (Ready), the device
is ready to read array data (includ-ing during the Erase
Suspend mode), or is in the standby mode.
QUERY COMMAND AND COMMON FLASH INTER-
FACE (CFI) MODE
MX29LV320C T/B 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 Automatic Select mode; however, it
is ignored otherwise.
The Reset command exits from the CFI mode to the
Read mode, or Erase Suspend mode, or Automatic Se-
lect mode. The command is valid only when the device is
in the CFI mode.
