Input-
Addresses: These inputs are registered and must meet the set
Synchronous up and hold times around the rising edge of CLK. The burst
countergeneratesinternaladdressesassociatedwithA0andA1,
during burst cycle and wait cycle.

BWa
Input-
Byte Write: A byte write is LOW for a WRITE cycle and HIGH for
BWb Synchronous a READ cycle. BWa controls DQa. BWb controls DQb. BWc
BWc
BWd
controls DQc. BWd controls DQd. Data I/O are high impedance
if either of these inputs are LOW, conditioned by BWE being
LOW.

Input-
Write Enable: This active LOW input gates byte write operations
Synchronous and must meet the set-up and hold times around the rising edge
of CLK.
Input-
Global Write: This active LOW input allows a full 36-bit Write to
Synchronous occur independent of the BWE and BWn lines and must meet the
set-up and hold times around the rising edge of CLK.
CLK
Input-
Clock: This signal registers the addresses, data, chip enables,
Synchronous write control, and burst control inputs on its rising edge. All
synchronous inputs must meet set up and hold times around the
clock’s rising edge.

ADV
Input-
Address Advance: This active LOW input is used to control the
Synchronous internal burst counter. A HIGH on this pin generates wait cycle
(no address advance).

ADSP
ADSC
Input-
Address Status Processor: This active LOW input, along with
Synchronous CE being LOW, causes a new external address to be registered
and a READ cycle is initiated using the new address.
Input-
Address Status Controller: This active LOW input causes
Synchronous device to be deselected or selected along with new external
address to be registered. A Read or Write cycle is initiated
depending upon write control inputs.

Input-
Static
Mode: This input selects the burst sequence. A LOW on this pin
selects LinearBurst. ANC orHIGH onthis pinselects Interleaved
Burst.
ZZ
Input-
Sleep: This active HIGH input puts the device in low power
Asynchronous consumption standby mode. For normal operation, this input has
to be either LOW or NC (No Connect).
