I/O
Multiplexed Address/Data input/output
CE#
Input
Chip Enable. Asynchronous relative to CLK for the Burst mode.

No Connected internally
RDY
Output
Ready. Indicates when valid burst data is ready to be read
CLK
Input
The first rising edge of CLK in conjunction with AVD# low latches address input and activates burst
mode operation. After the initial word is output, subsequent rising edges of CLK increment the
internal address counter. CLK should remain low during asynchronous access
AVD#
Input
Address Valid input. Indicates to device that the valid address is present on the address inputs
(address bits A15 – A0 are multiplexed, address bits Amax – A16 are address only).
V
= for asynchronous mode, indicates valid address; for burst mode, cause staring address to be
latched on rising edge of CLK.
V
IH
= device ignores address inputs
RESET#
Input
Hardware Reset. Low = device resets and returns to reading array data.
WP#
Input
Write Protect. At V
, disables program and erase functions in the four top sectors. Should be at V
IH
for all other conditions.
V
PP
Input
Accelerated input.
At V
HH
, accelerates programming; automatically places device in unlock bypass mode.
At V
,disables all program and erase functions.
Should be at V
