PRELIMINARY INFORMATION  
AUGUST 2005  
DESCRIPTION  
FEATURES  
The ISSI IS61(64)LF12832A,  
IS64VF12832A,  
• Internal self-timed write cycle  
• Individual Byte Write Control and Global Write  
IS61(64)LF/VF12836A and IS61(64)LF/VF25618A are  
high-speed, low-powersynchronousstaticRAMs designed  
to provide burstable, high-performance memory for commu-  
nication and networking applications. The  
IS61(64)LF12832A is organized as 131,072 words by 32  
bits. The IS61(64)LF/VF12836A is organized as 131,072  
words by 36 bits. The IS61(64)LF/VF25618A is organized  
as 262,144 words by 18 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 syn-  
chronous inputs pass through registers controlled by a  
positive-edge-triggered single clock input.  
• Clock controlled, registered address, data and  
control  
• Burst sequence control using MODE input  
•
Three chip enable option for simple depth expan-  
sion 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  
the rising edge of the clock input. Write cycles can be one  
to four bytes wide as controlled by the write control inputs.  
• Snooze MODE for reduced-power standby  
• Power Supply  
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.  
LF: VDD 3.3V + 5%, VDDQ 3.3V/2.5V + 5%  
VF: VDD 2.5V -5% +10%, VDDQ 2.5V -5% +10%  
• JEDEC 100-Pin TQFP, 119-pin PBGA, and  
165-pin PBGA packages  
• Automotive temperature available  
• Lead-free available  
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 ad-  
vance) 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.
