CY7C198-15LMB

The CY7C198-15LMB is designed as high performance CMOS static RAM organized as 32,768 words x8 bit. Easy memory expansion is provided by an active low chip enable and active low output enable and three-state drivers. This device has an automatic power-down feature, reducing the power consumption by 80% when deselected.

It has seven features. (1)High speed 15ns. (2)CMOS for optimum speed/power. (3)Low active power 990mW. (4)Low standby power 195mW. (5)TTL compatible inputs and outputs. (6)Automatic power-down when deselected. (7)Easy memory expansion with CE and OE features. Those are all the main features.

Some absolute maximum ratings 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 to ground potential pin 28 to pin 14 would be -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 output current into outputs low would be 20mA. (7)Its static discharge voltage would be >2001V. (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 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 -0.5V and max 0.8V. (5)Its input load current would be min -5uA and max +5uA. (6)Its output leakage current would be min -5uA and max +5uA. (7)Its output short circuit current would be max -300mA. And so on.
