EM562161

EtronTech Features Single power supply voltage of 2.7V to 3.6V Power down features using CE1# and CE2 Low operating current : 30mA(max for 55 ns) Maximum Standby current : 10µA at 3.6 V Data retention supply voltage: 1.5V to 3.6V Direct TTL compatibility for all input and output Wide operating temperature range: -40°C to 85°C Package type: 48-ball TFBGA, 6x8mm 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.
