FEATURES  
DESCRIPTION  
• High-speed access time: 45ns, 55ns, 70ns  
• CMOS low power operation  
– 36 mW (typical) operating  
TheISSIIS62WV12816ALL/IS62WV12816BLLare high-  
speed, 2M bit static RAMs organized as 128K words by 16  
bits. It is fabricated using ISSI's high-performance CMOS  
technology. This highly reliable process coupled with  
innovative circuit design techniques, yields high-  
performance and low power consumption devices.  
– 9 µW (typical) CMOS standby  
• TTL compatible interface levels  
• Single power supply  
When CS1 is HIGH (deselected) or when CS2 is LOW  
(deselected) or when CS1 is LOW, CS2 is HIGH and both  
LBandUBareHIGH, thedeviceassumesastandbymode  
at which the power dissipation can be reduced down with  
CMOS input levels.  
– 1.65V--2.2V VDD (62WV12816ALL)  
– 2.5V--3.6V VDD (62WV12816BLL)  
Easy memory expansion is provided by using Chip Enable  
and Output Enable inputs. 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.  
• Fully static operation: no clock or refresh  
required  
• Three state outputs  
• Data control for upper and lower bytes  
• Industrial temperature available  
• 2CS Option Available  
TheIS62WV12816ALLandIS62WV12816BLLarepackaged  
intheJEDECstandard48-pinminiBGA(6mmx8mm)and  
44-Pin TSOP (TYPE II).  
• Lead-free available
