ISSI  
256K x 16 HIGH SPEED ASYNCHRONOUS  
CMOS STATIC RAM WITH 3.3V SUPPLY  
JULY2006  
FEATURES  
DESCRIPTION  
The ISSI IS64LV25616AL is a high-speed, 4,194,304-bit  
static RAM organized as 262,144 words by 16 bits. It is  
fabricated using ISSI's high-performance CMOS technol-  
ogy. This highly reliable process coupled with innovative  
circuitdesigntechniques,yieldshigh-performanceandlow  
powerconsumptiondevices.  
• High-speed access time: 10, 12 ns  
• CMOS low power operation  
• Low stand-by power:  
Less than 5 mA (typ.) CMOS stand-by  
• TTL compatible interface levels  
• Single 3.3V power supply  
When CE is HIGH (deselected), the device assumes a  
standby mode at which the power dissipation can be  
reduced down with CMOS input levels.  
• Fully static operation: no clock or refresh  
required  
• Three state outputs  
EasymemoryexpansionisprovidedbyusingChipEnable  
and Output Enable inputs, CE and OE. The active LOW  
Write Enable (WE) controls both writing and reading of the  
memory. A data byte allows Upper Byte (UB) and Lower  
Byte (LB) access.  
• Data control for upper and lower bytes  
• Industrial temperature available  
• Temperature Offerings:  
Option A1: –40oC to +85oC  
Option A2: –40oC to +105oC  
Option A3: –40oC to +125oC  
• Lead-free available  
The IS64LV25616AL is packaged in the JEDEC standard  
44-pinTSOPTypeIIand48-pinMiniBGA(8mmx10mm).
