IS61LV6432  
64K x 32 SYNCHRONOUS  
PIPELINE STATIC RAM  
ISSI  
MAY 1998  
FEATURES  
DESCRIPTION  
The ISSI IS61LV6432 is a high-speed, low-power synchro-  
nous static RAM designed to provide a burstable, high-  
performance, secondary cache for the Pentium™, 680X0™,  
and PowerPC™ microprocessors. It is organized as 65,536  
words by 32 bits, fabricated with ISSI's advanced CMOS  
technology. The device integrates a 2-bit burst counter, high-  
speed SRAM core, and high-drive capability outputs into a  
single monolithic circuit. All synchronous inputs pass through  
registers controlled by a positive-edge-triggered single clock  
input.  
• Internal self-timed write cycle  
• Individual Byte Write Control and Global Write  
• Clock controlled, registered address, data and  
control  
• Pentium™ or linear burst sequence control  
using MODE input  
• Three chip enables for simple depth expansion  
and address pipelining  
• Common data inputs and data outputs  
• Power-down control by ZZ input  
Write cycles are internally self-timed and are initiated by the  
rising edge of the clock input. Write cycles can be from one to  
four bytes wide as controlled by the write control inputs.  
• JEDEC 100-Pin TQFP and PQFP package  
• 3.3V VCC and 2.5V VCCQ for 2.5 I/O's  
Separate byte enables allow individual bytes to be written.  
BW1 controls DQ1-DQ8, BW2 controls DQ9-DQ16, BW3  
controlsDQ17-DQ24,BW4controlsDQ25-DQ32,conditioned  
byBWEbeingLOW.ALOWonGWinputwouldcauseallbytes  
to be written.  
• Two Clock enables and one Clock disable to  
eliminate multiple bank bus contention.  
• Control pins mode upon power-up:  
– MODE in interleave burst mode  
– ZZ in normal operation mode  
These control pins can be connected to GNDQ  
or VCCQ to alter their power-up state  
Bursts can be initiated with either ADSP (Address Status  
Processor) or ADSC (Address Status Cache Controller) input  
pins. Subsequent burst addresses can be generated inter-  
nally by the IS61LV6432 and controlled by the ADV (burst  
address advance) input pin.  
• Industrial temperature available  
Asynchronoussignalsincludeoutputenable(OE),sleepmode  
input(ZZ), clock(CLK)andburstmodeinput(MODE). AHIGH  
input on the ZZ pin puts the SRAM in the power-down state.  
When ZZ is pulled LOW (or no connect), the SRAM normally  
operates after three cycles of the wake-up period. A LOW  
input, i.e., GNDQ, on MODE pin selects LINEAR Burst. AVCCQ  
(or no connect) on MODE pin selects INTERLEAVED Burst.
