IS41C16256  
IS41LV16256  
256K x 16 (4-MBIT) DYNAMIC RAM  
WITH EDO PAGE MODE  
DESCRIPTION  
FEATURES  
The ICSI IS41C16256 and IS41LV16256 is a 262,144 x 16-  
bit high-performance CMOS Dynamic Random Access Memo-  
ries. The IS41C16256 offer an accelerated cycle access  
called EDO Page Mode. EDO Page Mode allows 512 random  
accesses within a single row with access cycle time as short  
as 10 ns per 16-bit word. The Byte Write control, of upper and  
lower byte, makes the IS41C16256 ideal for use in  
16-, 32-bit wide data bus systems.  
• Extended Data-Out (EDO) Page Mode access cycle  
• TTL compatible inputs and outputs; tristate I/O  
• Refresh Interval: 512 cycles /8 ms  
• Refresh Mode: RAS-Only, CAS-before-RAS (CBR),  
Hidden  
• Single power supply:  
5V ± 10% (IS41C16256)  
3.3V ± 10% (IS41LV16256)  
• Byte Write and Byte Read operation via two CAS  
• Industrial Temperature Range -40oC to 85oC  
These features make the IS41C16256and IS41LV16256 ideally  
suited for high-bandwidth graphics, digital signal processing,  
high-performance computing systems, and peripheral  
applications.  
The IS41C16256 is packaged in a 40-pin 400mil SOJ and  
400mil TSOP-2.
