Address inputs for WS256N
Data input/output
Chip Enable input. Asynchronous relative to CLK for
the Burst mode.
Output Enable input. Asynchronous relative to CLK
for the Burst mode.
Write Enable input.
Device Power Supply
(1.65 – 1.95 V).
Input & Output Buffer Power Supply (1.35 – 1.70 V).
Ground
Output Buffer Ground
No Connect; not connected internally
Ready output. Indicates the status of the Burst read.
Clock input. In burst mode, after the initial word is
output, subsequent active edges of CLK increment
the internal address counter. Should be at V
while in asynchronous mode
Address Valid input. Indicates to device that the
valid address is present on the address inputs.
Low = for asynchronous mode, indicates valid
address; for burst mode, causes starting address to
be latched.
High = device ignores address inputs
Hardware reset input. Low = device resets and
returns to reading array data
Hardware write protect input. At V
program and erase functions in the four outermost
sectors. Should be at V
Accelerated input. At V
programming; automatically places device in unlock
bypass mode. At V
functions. Should be at V
