Overview
The EM562161 is a 2,097,152-bit SRAM organized as
131,072 words by 16 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
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 EM562161 can be used
in environments exhibiting extreme temperature
conditions.
