A0–A19
20-bit address bus for 32 Mb device, (19-bit for 16 Mb). A9 supports 12 V autoselect inputs.
DQ0–DQ31
32-bit data inputs/outputs/float
CE#
Chip Enable Input. This signal is asynchronous relative to CLK for the burst mode.
OE#
Output Enable Input. This signal is asynchronous relative to CLK for the burst mode.
WE#
Write enable. This signal is asynchronous relative to CLK for the burst mode.
VSS
Device ground
NC
Pin not connected internally
RY/BY#
Ready/Busy output and open drain. When RY/BY# = VOH, the device is ready to accept read operations and
commands. When RY/BY# = VOL, the device is either executing an embedded algorithm or the device is executing a
hardware reset operation.
CLK
Clock Input that can be tied to the system or microprocessor clock and provides the fundamental timing and internal
operating frequency.
ADV#
Load Burst Address input. Indicates that the valid address is present on the address inputs.
IND#
End of burst indicator for finite bursts only. IND is low when the last word in the burst sequence is at the data outputs.
WAIT#
Provides data valid feedback only when the burst length is set to continuous.
WP#
Write Protect input. When WP# = VOL, the two outermost bootblock sector in the 75% bank are write protected
regardless of other sector protection configurations.
ACC
Acceleration input. When taken to 12 V, program and erase operations are accelerated. When not used for acceleration,
ACC = VSS to VCC.
VIO (VCCQ)
Output Buffer Power Supply (1.65 V to 2.75 V)
VCC
Chip Power Supply (2.5 V to 2.75 V) or (3.00 V to 3.60 V)
RESET#
Hardware reset input
MCH
Must Connect High (to VCC)
