A0-A16  
Input-  
Synchronous  
Addresses: These inputs are registered and must meet the setup and hold times around  
the rising edge of CLK. The burst counter generates internal addresses associated with A0  
and A1, during burst cycle and wait cycle.

BW1#,  
BW2#,

Input-  
Synchronous  
Byte Write: A byte write is LOW for a WRITE cycle and HIGH for a READ cycle. BW1#  
controls DQ1-DQ8. BW2# controls DQ9-DQ16. BW3# controls DQ17-DQ24. BW4#  
controls DQ25-DQ32. Data I/O are high impedance if either of these inputs are LOW,  
conditioned by BWE# being LOW.

BWE#  
Input-  
Synchronous  
Write Enable: This active LOW input gates byte write operations and must meet the setup  
and hold times around the rising edge of CLK.  
GW#  
Input-  
Synchronous  
Global Write: This active LOW input allows a full 32-bit WRITE to occur independent of the  
BWE# and BWn# lines and must meet the setup and hold times around the rising edge of  
CLK.  
89  
CLK  
Input-  
Synchronous  
Clock: This signal registers the addresses, data, chip enables, write control and burst  
control inputs on its rising edge. All synchronous inputs must meet setup and hold times  
around the clock’s rising edge.  
98  
92  
CE#  
Input-  
Synchronous  
Chip Enable: This active LOW input is used to enable the device and to gate ADSP#.  
CE2#  
Input-  
Chip Enable: This active LOW input is used to enable the device.
