FEATURES  
DESCRIPTION  
The ISSI IS61SF25636 and IS61SF51218 are high-speed,  
low-powersynchronousstaticRAMsdesignedtoprovidea  
burstableandhigh-performancesolution. TheIS61SF25636  
isorganizedas262,144wordsby36bits.TheIS61SF51218  
is organized as 524,288 words by 18 bits. Fabricated with  
ISSI'sadvancedCMOStechnology,thedeviceintegratesa  
2-bit burst counter, high-speed SRAM core, and high-drive  
capability outputs into a single monolithic circuit. All syn-  
chronous inputs pass through registers that are 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  
Threechipenableoptionforsimpledepthexpansion  
and address pipelining  
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.  
• Common data inputs and data outputs  
• JEDEC 100-Pin TQFP  
Separate byte enables allow individual bytes to be written.  
Byte write operation is performed by using byte write  
enable (BWE) input combined with one or more individual  
byte write signals (BWx). In addition, Global Write (GW)  
is available for writing all bytes at one time, regardless of  
the byte write controls.  
• Single +3.3V, +10%, –5% power supply  
• Power-down snooze mode  
• 3.3V I/O for SF  
• Snooze MODE for reduced-power standby  
Bursts can be initiated with either ADSP (Address Status  
Processor) or ADSC (Address Status Cache Controller)  
input pins. Subsequent burst addresses can be generated  
internally and controlled by the ADV (burst address  
advance) input pin.  
The mode pin is used to select the burst sequence order,  
LinearburstisachievedwhenthispinistiedLOW. Interleave  
burst is achieved when this pin is tied HIGH or left floating.
