Description

The CY62148BLL-70SC is designed as a high-performance CMOS static RAM organized as 512K words by 8bits. Easy memory expansion is provided by an active LOW chip enable (CE), an active LOW output enable (OE), and three-state drivers. CY62148BLL-70SC has an automatic power-down feature that reduces power consumption by more than 99% when deselected.

CY62148BLL-70SC has seven features. (1)4.5V to 5.5V operation. (2)Low active power which means typical active current: 2.5mA at f=1MHz and typical active current: 12.5mA at f=fmax. (3)Low standby current. (4)Automatic power-down when deselected. (5)TTL-compatible inputs and outputs. (6)Easy memory expansion with CE and OE features. (7)CMOS for optimum speed/power. Those are all the main features.

Some absolute maximum ratings of CY62148BLL-70SC have been concluded into several points as follow. (1)Its storage temperature range would be from -65°C to 150°C. (2)Its ambient temperature with power applied would be from -55°C to 125°C. (3)Its supply voltage on Vcc to relative GND would be from -0.5V to 7.0V. (4)Its DC voltage applied to outputs in high Z state would be from -0.5V to Vcc+0.5V. (5)Its DC input voltage would be from -0.5V to Vcc+0.5V. (6)Its current into outputs low would be 20mA. (7)Its static discharge voltage would be 2001V per MIL-STD-883, method 3015. (8)Its latch-up current would be >200mA. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of CY62148BLL-70SC are concluded as follow. (1)Its output high voltage would be min 2.4V. (2)Its output low voltage would be max 0.4V. (3)Its input high voltage would be min 2.2V and max Vcc+0.3V. (4)Its input low voltage would be min -0.3V and max 0.8V. (5)Its input leakage current would be min -1uA and max +1uA. (6)Its output leakage current would be min -1uA and max +1uA. (7)Its input capacitance would be max 6pF. And so on.
