asserted low. There are three control inputs. CE1# and
CE2 are used to select the device and for data retention
control, and output enable (OE#) provides fast memory
access. Data byte control pin (LB#,UB#) provides 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 operating range from -40°C to 85°C,
the EM562081 can be used in environments exhibiting
extreme temperature conditions.

Overview
The EM562081 is a 2,097,152-bit SRAM organized as
262,144 words by 8 bits. It is designed with advanced
CMOS technology. This Device operates from a single
2.7V to 3.6V power supply. Advanced circuit
technology provides both high speed and low power. It
is automatically placed in low-power mode when chip
enable (CE1#) is asserted high or (CE2) is
