Features  
64Kx32CMOSHighSpeed  
Static RAM  
64Kx32 bit CMOS Static  
The EDI8L3265C is a high speed, high performance, four  
megabit density Static RAM organized as a 64Kx32 bit  
array(  
Random Access Memory Array  
• Fast Access Times: 12*, 15, 20, and 25ns  
• Individual Byte Selects  
Four Byte Selects, two Chip Enables, Write Control, and  
Output Enable provide the user with a flexible memory  
solution( The user may independently enable each of the  
four bytes, and, with minimal additional peripheral logic,  
the unit may be configured as a 128Kx16 array(  
Fully asynchronous circuitry is used, requiring no clocks or  
refreshing for operation and providing equal access and  
cycle times for ease of use(  
• User Configurable Organization  
with Minimal Additional Logic  
• Master Output Enable and Write Control  
• TTL Compatible Inputs and Outputs  
• Fully Static, No Clocks  
Surface Mount Package  
The EDI8L3265C, allows 2 megabits of memory to be  
placed in less than 0(990 square inches of board space(  
The EDI8L3265C can be upgraded to 128K, 256K or  
512Kx32 in the same footprint using the EDI8L32128,  
EDI8L32256 or the EDI8L32512C( ꢀSee page 6 for up-  
grade paths)(  
• 68 Lead PLCC, No( 99 ꢀJEDEC-M0-47AE)  
• Small Footprint, 0(990 Sq( In(  
• Multiple Ground Pins for Maximum  
Noise Immunity
