IS61SP6464  
64K x 64 SYNCHRONOUS  
PIPELINE STATIC RAM  
ISSI  
APRIL 2001  
FEATURES  
DESCRIPTION  
The ISSI IS61SP6464 is a high-speed, low-power synchro-  
nous static RAM designed to provide a burstable, high-  
performance, secondary cache for the i486™, Pentium™,  
680X0™, and PowerPC™ microprocessors. It is organized  
as 65,536 words by 64 bits, fabricated with ISSI's advanced  
CMOStechnology.Thedeviceintegratesa2-bitburstcounter,  
high-speed SRAM core, and high-drive capability outputs into  
asinglemonolithiccircuit.Allsynchronousinputspassthrough  
registers controlled by a positive-edge-triggered single clock  
input.  
• Fast access time:  
– 133, 117, 100 MHz; 6 ns (83 MHz);  
7 ns (75 MHz); 8 ns (66 MHz)  
• 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  
Write cycles are internally self-timed and are initiated by the  
rising edge of the clock input. Write cycles can be from one to  
eight bytes wide as controlled by the write control inputs.  
• Five chip enables for simple depth expansion  
and address pipelining  
• Common data inputs and data outputs  
• Power-down control by ZZ input  
• JEDEC 128-Pin TQFP 14mm x 20mm  
package  
Separate byte enables allow individual bytes to be written.  
BW1 controls I/O1-I/O8, BW2 controls I/O9-I/O16, BW3 con-  
trols I/O17-I/O24, BW4 controls I/O25-I/O32, BW5 controls  
I/O33-I/O40, BW6 controls I/O41-I/O48, BW7 controls I/O49-  
I/O56, BW8 controls I/O57-I/O64, conditioned by BWE being  
LOW. A LOW onGW input would cause all bytes to be written.  
• Single +3.3V power supply  
• Control pins mode upon power-up:  
– MODE in interleave burst mode  
– ZZ in normal operation mode  
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 IS61SP6464 and controlled by the ADV (burst  
address advance) input pin.  
These control pins can be connected to GNDQ  
or VCCQ to alter their power-up state  
Asynchronoussignalsincludeoutputenable(OE),sleepmode  
input(ZZ), andburstmodeinput(MODE). AHIGHinputonthe  
ZZ pin puts the SRAM in the power-down state. When ZZ is  
pulled LOW (or no connect), the SRAM normally operates  
after the wake-up period. A LOW input, i.e., GNDQ, on MODE  
pin selects LINEAR Burst. A VCCQ (or no connect) on MODE  
pin selects INTERLEAVED Burst.  
ISSI reserves the right to make changes to its products at any time without notice in order to improve design and supply the best possible product. We assume no responsibility for any  
errors which may appear in this publication. © Copyright 2001, Integrated Silicon Solution, Inc.
