FEATURES  
DESCRIPTION  
Internal self-timed write cycle  
The 18Mb product family features high-speed, low-  
power synchronous static RAMs designed to provide  
burstable, high-performance memory for  
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  
communication and networking applications. The  
IS61LPS/VPS/VVPS51236B are organized as 524,288  
words by 36bits. The IS61LPS/VPS/VVPS102418B are  
organized as 1,048,576 words by 18bits. 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.  
Snooze MODE for reduced-power standby  
JEDEC 100-pin QFP, 165-ball BGA and 119-ball  
BGA packages  
Power supply:  
LPS: VDD 3.3V (± 5%), VDDQ 3.3V/2.5V (± 5%)  
VPS: VDD 2.5V (± 5%), VDDQ 2.5V (± 5%)  
VVPS: VDD 1.8V (± 5%), VDDQ 1.8V (± 5%)  
JTAG Boundary Scan for BGA packages  
Commercial, Industrial and Automotive  
temperature support  
Write cycles are internally self-timed and are initiated  
by the rising edge of the clock input. Write cycles can  
be one to four bytes wide as controlled by the write  
control inputs.  
Separate byte enables allow individual bytes to be  
written. 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  
Lead-free available  
For leaded options, please contact ISSI  
addition, Global Write (/GW) is available for writing all  
bytes at one time, regardless of the byte write controls.  
FAST ACCESS TIME  
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. Linear burst is achieved when this pin is tied  
LOW. Interleave burst is achieved when this pin is tied  
HIGH or left floating.
