Data input/output.
DQ15: Data input/output in word mode.
A-1: LSB address input in byte mode.
Chip Enable.
Output Enable.
Write Enable.
Device Power Supply.
Versatile IO Input.
Ground.
Not connected internally.
Ready/Busy. Indicates whether an Embedded Algorithm is in progress or complete. At
V
IL
, the device is actively erasing or programming. At High Z, the device is in ready.
Selects data bus width. At VIL, the device is in byte configuration and data I/O pins DQ0-
DQ7 are active and DQ15/A-1 becomes the LSB address input. At VIH, the device is in
word configuration and data I/O pins DQ0-DQ15 are active.
Hardware Reset. Low = device resets and returns to reading array data.
Write Protect/Acceleration Input. At V
IL
, disables program and erase functions in the
outermost sectors. At V
HH
, accelerates programming; automatically places device in
unlock bypass mode. Should be at V
IH
for all other conditions. WP# has an internal pull-
up; when unconnected, WP# is at V
IH
