Ordering Information
Overview
The EM584161 is a 4,194,304-bit SRAM organized as 262,144 words by 16 bits. It is designed with advanced
CMOS technology.
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.
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 EM584161 can be used in environments exhibiting
extreme temperature conditions.
