Pin Description
Overview
The EM566168 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 CS1# or both UB# and LB# are asserted high or CS2
is asserted low. There are three control inputs. CS1# and CS2 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 EM566168 can be used in
environments exhibiting extreme temperature conditions.
