Overview  
The EM565168 is a 8M-bit Pseudo SRAM organized as 512K words by 16 bits. It is designed with advanced  
CMOS technology specified RAM featuring low power static RAM compatible function and pin configuration.  
This device operates from a single power supply. Advanced circuit technology provides both high speed and  
low power. It is automatically placed in low-power mode when CE1# or both UB# and LB# are asserted high or  
CE2 is asserted low. There are three control inputs. CE1# and CE2 are used to select the device, and output  
enable (OE#) provides fast memory access. Data byte control pins (LB#,UB#) provide lower and upper byte  
access. This device is well suited to various microprocessor system applications where high speed, low power  
and battery backup are required. And, with a guaranteed wide operating range, the EM565168 can be used in  
environments exhibiting extreme temperature conditions.
