IS61LV25616L  
ISSI  
256K x 16 HIGH SPEED ASYNCHRONOUS  
CMOS STATIC RAM WITH 3.3V SUPPLY  
JUNE 2002  
DESCRIPTION  
FEATURES  
The ISSI IS61LV25616L 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  
power consumption devices.  
• High-speed access time:  
— 10, 12, and 15 ns  
• Low Active Power  
— Less than 90mA (typ.) Active Current  
• Low standby power:  
— Less than 1 mA (typ.) CMOS standby  
When CE is HIGH (deselected), the device assumes a  
standby mode at which the power dissipation can be  
reduced down with CMOS input levels.  
• TTL compatible interface levels  
• Single 3.3V power supply  
• Fully static operation: no clock or refresh  
required  
Easy memory expansion is provided by using Chip Enable  
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.  
• Three state outputs  
• Data control for upper and lower bytes  
• Industrial temperature available  
The IS61LV25616L is packaged in the JEDEC standard  
44-pin400-milSOJ,44-pinTSOPTypeII,44-pinLQFPand  
48-pin Mini BGA (8mm x 10mm).
