IS61LV2568  
256K x 8 HIGH-SPEED CMOS STATIC RAM  
FEATURES  
DESCRIPTION  
The ISSI IS61LV2568 is a very high-speed, low power,  
262,144-wordby8-bitCMOSstaticRAM.TheIS61LV2568  
is fabricated using ISSI's high-performance CMOS tech-  
nology. This highly reliable process coupled with innova-  
tive circuit design techniques, yields higher performance  
and low power consumption devices.  
• High-speed access times:  
8, 10, 12 and 15 ns  
• High-performance, low-power CMOS process  
• Multiple center power and ground pins for  
greater noise immunity  
• Easy memory expansion with CE and OE  
options  
When CE is HIGH (deselected), the device assumes a  
standby mode at which the power dissipation can be  
reduced down to 36mW (max.) with CMOS input levels.  
CE power-down  
The IS61LV2568 operates from a single 3.3V power  
supply and all inputs are TTL-compatible.  
• Low power: 540 mW @ 10 ns  
36 mW standby mode  
The IS61LV2568 is available in 36-pin 400-mil SOJ, and  
44-pin TSOP (Type II) packages.  
• TTL compatible inputs and outputs  
• Single 3.3V 10ꢀ power supply  
• Packages available:  
– 36-pin 400-mil SOJ  
– 44-pin TSOP (Type II)
