FEATURES  
DESCRIPTION  
The ISSI IS62WV5128ALL / IS62WV5128BLL are high-  
speed, 4M bit static RAMs organized as 512K words by 8  
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.  
• High-speed access time: 55ns, 70ns  
• CMOS low power operation  
36 mW (typical) operating  
9 µW (typical) CMOS standby  
• TTL compatible interface levels  
• Single power supply  
When CS1 is HIGH (deselected) the device assumes a  
standby mode at which the power dissipation can be  
reduced down with CMOS input levels.  
1.65V – 2.2V VDD (IS62WV5128ALL)  
2.5V – 3.6V VDD (IS62WV5128BLL)  
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.  
• Fully static operation: no clock or refresh  
required  
TheIS62WV5128ALLandIS62WV5128BLLarepackaged  
in the JEDEC standard 32-pin TSOP (TYPE I), 32-pin  
sTSOP (TYPE I), and 32-pin TSOP (Type II).  
• Three state outputs  
• Industrial temperature available
