=
Ready output; indicates the status of the Burst read. V
OL
= data invalid.
V
OH
= data valid
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
CLK
=
AVD#
=
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
IL
= for asynchronous mode, indicates valid address; for burst mode, causes starting
address to be latched on rising edge of CLK.
V
IH
= device ignores address inputs
Hardware reset input. V
IL
= device resets and returns to reading array data
Hardware write protect input. V
IL
= disables writes to SA257–258 (S29NS256N),
SA129–130 (S29NS128N) or SA129-130 (S29NS064N). Should be at V
