bits that are don’t care. When all necessary bits have been set as required, the programming equipment may
then read the corresponding identifier code on DQ7–DQ0.
To access the autoselect codes in-system, the host system can issue the autoselect command via the
command. This method does not require VID. See
on using the autoselect mode. Autoselect mode can be used in either synchronous (Burst) mode or
asynchronous (Non Burst) mode.
The system must write the reset command to exit the autoselect mode and return to reading the array data.

The autoselect codes can also be accessed in-system via command sequences. See

data outputs and the voltages tolerated at its data inputs to the same voltage level that is asserted on the V
pin. The output voltage generated on the device is determined based on the V
(CD-J), a V
lower than 2.5 V. For a 3.3 V V
than 3.0 V.
These devices are capable of several modes of programming and or erase operations which are described in
detail in the following sections. However, prior to any programming and or erase operation, devices must be
set up appropriately as outlined in the configuration register
write operation, to write a command or command sequence (including programming data to the device and
erasing sectors of memory), the system must drive ADV# and CE# to V
address to the device, and drive WE# and CE# to V
programming data.
