FEATURES  
DESCRIPTION  
• TTL compatible inputs and outputs  
• Refresh Interval: 512 cycles/8 ms  
TheISSI IS41C16256andIS41LV16256are262,144x16-bit  
high-performanceCMOSDynamicRandomAccessMemory. Both  
productsofferacceleratedcycleaccessEDOPageMode. EDO  
PageModeallows512randomaccesseswithinasinglerowwith  
accesscycletimeasshortas10nsper16-bitword.TheByteWrite  
control, of upper and lower byte, makes the IS41C16256 and  
IS41LV16256idealforusein16and32-bitwidedatabussystems.  
• Refresh Mode : RAS-Only, CAS-before-RAS  
(CBR), and Hidden  
• JEDEC standard pinout  
• Single power supply  
5V ± 10% (IS41C16256)  
ThesefeaturesmaketheIS41C16256andIS41LV1626 ideally  
suited for high band-width graphics, digital signal processing,  
high-performancecomputingsystems,andperipheralapplications.  
3.3V ± 10% (IS41LV16256)  
• Byte Write and Byte Read operation via two CAS  
• Extended Temperature Range -30oC to 85oC  
• Industrail Temperature Range -40oC to 85oC  
The IS41C16256 and IS41LV16256 are packaged in 40-pin  
400-mil SOJ and TSOP (Type II).
