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.
