PIPELINE 'NO WAIT' STATE BUS SRAM  
PRELIMINARY INFORMATION  
APRIL 2001  
FEATURES  
DESCRIPTION  
The 8 Meg 'NP' product family feature high-speed,  
low-power synchronous static RAMs designed to provide  
a burstable, high-performance, 'no wait' state, device for  
network and communications customers. They are  
organized as 262,144 words by 32 bits, 262,144 words  
by 36 bits and 524,288 words by 18 bits, fabricated with  
ISSI's advanced CMOS technology.  
• 100 percent bus utilization  
• No wait cycles between Read and Write  
• Internal self-timed write cycle  
• Individual Byte Write Control  
• Single R/W (Read/Write) control pin  
• Clock controlled, registered address,  
data and control  
Incorporating a 'no wait' state feature, wait cycles are  
eliminated when the bus switches from read to write, or  
write to read. This device integrates a 2-bit burst counter,  
high-speed SRAM core, and high-drive capability outputs  
into a single monolithic circuit.  
• Interleaved or linear burst sequence control  
using MODE input  
• Three chip enables for simple depth expansion  
and address pipelining for TQFP  
Allsynchronousinputspassthroughregistersarecontrolled  
byapositive-edge-triggeredsingleclockinput.Operations  
may be suspended and all synchronous inputs ignored  
when Clock Enable, CKE is HIGH. In this state the internal  
device will hold their previous values.  
• Power Down mode  
• Common data inputs and data outputs  
• CKE pin to enable clock and suspend operation  
• JEDEC 100-pin TQFP, 119 PBGA package  
• Single +3.3V power supply (± 5%)  
• NP Version: 3.3V I/O Supply Voltage  
• NLP Version: 2.5V I/O Supply Voltage  
• Industrialtemperatureavailable  
All Read, Write and Deselect cycles are initiated by the  
ADV input. When the ADV is HIGH the internal burst  
counter is incremented. New external addresses can be  
loaded when ADV is LOW.  
Write cycles are internally self-timed and are initiated by  
the rising edge of the clock inputs and when WE is LOW.  
Separate byte enables allow individual bytes to be written.  
A burst mode pin (MODE) defines the order of the burst  
sequence.WhentiedHIGH,theinterleavedburstsequence  
is selected. When tied LOW, the linear burst sequence is  
selected.
