ISSI  
256K x 36 and 512K x 18  
9Mb, FLOW THROUGH 'NO WAIT'  
STATE BUS SRAM  
AUGUST 2005  
FEATURES  
DESCRIPTION  
The 9 Meg 'NLF/NVF' product family feature high-speed,  
low-power synchronous static RAMs designed to provide  
a burstable, high-performance, 'no wait' state, device for  
networking and communications applications. They are  
organized as 256K words by 36 bits and 512K 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 Read/Write control pin  
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.  
• Clock controlled, registered address,  
data and control  
• Interleaved or linear burst sequence control using  
MODE input  
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.  
• Three chip enables for simple depth expansion  
and address pipelining  
• Power Down mode  
• Common data inputs and data outputs  
• CKE pin to enable clock and suspend operation  
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.  
• JEDEC 100-pin TQFP, 119-ball PBGA, and 165-  
ball PBGA packages  
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.  
• Power supply:  
NVF: VDD 2.5V (± 5%), VDDQ 2.5V (± 5%)  
NLF: VDD 3.3V (± 5%), VDDQ 3.3V/2.5V (± 5%)  
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.  
• JTAG Boundary Scan for PBGA packages  
• Industrial temperature available  
• Lead-free available
