CYM1465  
512K x 8 SRAM Module  
Features  
Functional Description  
• High-density 4-megabit SRAM module  
• High-speed CMOS SRAMs  
— Access time of 70 ns  
• Low active power  
The CYM1465 is a high-performance 4-megabit static RAM  
module organized as 512K words by 8 bits. This module is  
constructed using four 128K x 8 RAMs mounted on a substrate  
with pins. A decoder is used to interpret the higher-order ad-  
dresses (A and A ) and to select one of the four RAMs.

— 605 mW (max.)  
Writing to the module is accomplished when the chip select  
(CS) and write enable (WE) inputs are both LOW. Data on the  
eight input/output pins (I/O through I/O ) of the device is writ-  
• 2V data retention (L Version)  
• JEDEC-compatible pinout  
• 32-pin, 0.6-inch-wide DIP package  
• TTL-compatible inputs and outputs  
• Low profile

ten into the memory location specified on the address pins (A  
0
through A ). Reading the device is accomplished by taking  
18  
chip select and output enable (OE) LOW while write enable  
remains inactive or HIGH. Under these conditions, the con-  
tents of the memory location specified on the address pins (A  
— Max. height of 0.27 in.  
• Small PCB footprint

through A ) will appear on the eight appropriate data in-  
18  
put/output pins (I/O through I/O ).

— 0.98 sq. in.  
The input/output pins remain in a high-impedance state unless  
the module is selected, outputs are enabled, and write enable  
is HIGH.
