EDI88512CA  
White Electronic Designs  
512Kx8 Monolithic SRAM, SMD 5962-95600  
FEATURES  
The EDI88512CA is a 4 megabit Monolithic CMOS  
Static RAM.  
„
„
„
„
„
„
„
Access Times of 15, 17, 20, 25, 35, 45, 55ns  
Data Retention Function (LPA version)  
TTL Compatible Inputs and Outputs  
Fully Static, No Clocks  
The 32 pin DIPpinout adheres to the JEDEC evolutionary  
standard for the four megabit device.All 32 pin packages  
are pin for pin upgrades for the single chip enable 128K  
x 8, the EDI88128CS. Pins 1 and 30 become the higher  
order addresses.  
Organized as 512Kx8  
The 36 pin revolutionary pinout also adheres to the  
JEDEC standard for the four megabit device. The center  
pin power and ground pins help to reduce noise in high  
performance systems. The 36 pin pinout also allows the  
user an upgrade path to the future 2Mx8.  
Commercial, Industrial and Military Temperature Ranges  
32 lead JEDEC Approved Evolutionary Pinout
