IC41C8512  
IC41LV8512  
512K x 8 (4-MBIT) DYNAMIC RAM  
WITH EDO PAGE MODE  
DESCRIPTION  
FEATURES  
The ICSI IC41C8512 and IC41LV8512 is a 524,288 x 8-bit high-  
performance CMOS Dynamic Random Access Memories. The  
IC41C8512 offer an accelerated cycle access called EDO Page  
Mode. EDO Page Mode allows 1024 random accesses within  
a single row with access cycle time as short as 12 ns per 8-bit  
word.  
• Extended Data-Out (EDO) Page Mode access cycle  
• TTL compatible inputs and outputs; tristate I/O  
• Refresh Interval: 1024 cycles /16 ms  
• Refresh Mode: RAS-Only, CAS-before-RAS (CBR),  
Hidden  
• Single power supply:  
These features make the IC41C8512and IC41LV8512 ideally  
suited for, digital signal processing, high-performance audio  
systems, and peripheral applications.  
5V ± 10% (IC41C8512)  
3.3V ± 10% (IC41LV8512)  
• Industrail Temperature Range -40oC to 85oC  
The IC41C8512 is packaged in a 28-pin 400mil SOJ and 400mil  
TSOP-2.
