EM562161
128K x 16 Low Power SRAM
Preliminary, Rev 1.0 07/2001
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.
