SINGLE CYCLE DESELECT STATIC RAM  
DESCRIPTION  
FEATURES  
The ISSI IS61LPS/VPS25636A and IS61LPS/  
VPS51218Aarehigh-speed,low-powersynchronousstatic  
RAMsdesignedtoprovideburstable,high-performancememory  
for communication and networking applications. The  
IS61LPS/VPS25636A is organized as 262,144 words by  
36 bits and the IS61LPS/VPS51218A is organized as  
524,288 words by 18 bits. Fabricated with ISSI's ad-  
vanced 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  
• Burst sequence control using MODE input  
• Three chip enable option for simple depth  
expansion and address pipelining  
• Common data inputs and data outputs  
• Auto Power-down during deselect  
• Single cycle deselect  
Write cycles are internally self-timed and are initiated by  
therisingedgeoftheclockinput. Writecyclescanbeone  
tofourbyteswideascontrolledbythewritecontrolinputs.  
• Snooze MODE for reduced-power standby  
• JTAG Boundary Scan for PBGA package  
• Power Supply  
Separatebyteenablesallowindividualbytestobewritten.  
The byte write operation is performed by using the 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.  
LPS: VDD 3.3V + 5%, VDDQ 3.3V/2.5V + 5%  
VPS: VDD 2.5V + 5%, VDDQ 2.5V + 5%  
Bursts can be initiated with either ADSP (Address Status  
Processor) or ADSC (Address Status Cache Controller)  
inputpins.Subsequentburstaddressescanbegenerated  
internally and controlled by the ADV (burst address  
advance) input pin.  
• JEDEC 100-Pin TQFP, 119-ball PBGA, and  
165-ball PBGA packages  
• Lead-free available  
The mode pin is used to select the burst sequence order,  
Linear burst is achieved when this pin is tied LOW.  
Interleave burst is achieved when this pin is tied HIGH or  
left floating.
