Overview
The EM564081 is a 4,194,304-bit SRAM organized as 512K by 8 bits. It is designed with advanced CMOS
technology. This Device operates from a single 2.3V 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 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. 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 EM564081 can be used in
environments exhibiting extreme temperature conditions.
