Overview
The EM566169 is a 16M-bit Pseudo SRAM organized as 1M 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 EM566169 can be used in
environments exhibiting extreme temperature conditions.
